BNST beaded neuron Neuron located within the core of the nucleus (BSTov) that is termed a beaded neuron (BN) because of its rounded soma and numerous spherules along both dendrites and axon (Fig. 11). The soma measures from 12 to 17 micrometers in its widest axis and is nearly spherical, having a rather smooth profile. The soma issues two or three short primary dendrites, which usually run horizontally. After a short distance (10 to 40 micrometers), these proximal branches give rise to sets of two to five long, secondary dendrites. The occurrence of third to order dendrites is variable, as is their length (20 to 150 micrometers). A defining characteristic of BN dendrites is the presence of distinct varicosities that are virtually devoid of dendritic spines. The BN axon and its collaterals also exhibit a series of small spherules (0.3-0.5 um) united by thin axonal bridges (Lariva-Sahd, 2006, as reported in http://brancusi.usc.edu/bkms).

The cell somas of these neurons have been described as "spherical" in the anterior division of the AVDC and "globular" in the posterior division of the AVDC.

Cochlear nucleus chestnut cell Type of intrinsic neuron located in the granule cell layer of the cochlear nucleus, characterized by a small (~10 um) cell body and 1-2 stubby dendrites emerging from one side of the soma, ending in a terminal tuft. Finger-like projections emerge from both the dendritic tuft and the soma. The cell gets its name from the irregular surface of the cell soma, characterized by numerous scallops, blebs and other protrusions, giving it the appearance of a chestnut. At the ultrastructural level, the cell body and proximal dendrites are rich in Golgi apparatus, rough endoplasmic reticulum and free ribosomes with a large, centrally located pale nucleus with a smooth nuclear membrane. Although it resembles the unipolar brush cell in some respects, it is differentiated by the gradual tapering of the primary dendrites in the transition from the cell soma and the fact that every protuberance of the dendrite is "prominantly synaptic" according to Weedman et al. (1996). It is a target of mossy fiber synapses. Chestnut neuron

Colliculus superior deep vertical fusiform cell Deep vertical fusiform cells have cell bodies about 20 micrometers wide and their dendrites extend from the upper margin of the zone of vertical cells to the depth of the zone of optic fibers perhaps even deeper. The superficial and deep fields are usually notably different in the manner in which the dendrites branch and spread, the over to all size of the fields, the shapes of the fields, the type and density of spines, and the caliber of the dendrites. deep vertical fusiform cell Superior colliculus intermediate gray layer
Colliculus superior intermediate vertical fusiform cell The intermediate vertical fusiform cells have cell bodies 12 to 18 micrometers in diameter in the upper portion of the zone of vertical cells and their dendritic fields extend from the collicular surface to the deep margin of the zone of vertical cells (fig. 12b, 13). Intermediate vertical fusiform cells most often have a superficial field with relatively fewer spines, straighter, more even caliber dendrites that branch less often but more equally than those in the deep field of the same cell (figs. 12b, 13). intermediate vertical fusiform cell Superior colliculus optic layer
Colliculus superior inverted pyramidal cell The inverted pyramidal cell is similar to the pyramidal cell except that the cell body lies within the deep portion of the zone of horizontal cells. The superficial field is a circumsomatic field and the deep field is elongated to reach into the deeper portion of the zone of vertical cells. The cell body is about the size of an intermediate vertical fusiform cell soma. The axon is similar, but more apt to have collaterals to the superficial zones. Inverted pyramidal cells fall within the definition of the narrow field vertical cells. inverted pyramidal cell Superior colliculus superficial gray layer
Colliculus superior piriform cell The piriform cells have ovoid or cup shaped cell bodies, 10 to 15 micrometers in diameter, located within a narrow lamina along the deep margin of the zone of horizontal cells. The restriction of the piriform cell somata to the boundary between the zone of horizontal cells and the zone of vertical cells is remarkably accurate and consistent. The piriform cells give rise to 2 to 5 dendrites from the superficial surface, which course through the zone of horizontal cells to terminate just beneath the surface. As the ascending dendrites approach the surface they branch more frequently, almost always by equipartition, to form a complicated intermingling bouquet of slowly tapering dendrites, 150 to 350 micrometers in width and slightly less than 200 micrometers in depth. The axon most frequently takes its origin from the base of the soma, but sometimes it arises from one of the low order dendrites. From its origin the axon runs immediately down through the zone of vertical cells, occasionally with collaterals which may arborize within the superficial laminae. The axon is thin and smooth, occasionally with en passant varicosities. piriform cell

Superior colliculus optic layer
Colliculus superior pyramidal cell Pyramidal cells are similar to vertical fusiform cells in most respects. They have a vertically elongated cell body, about 15 micrometers in transverse diameter, in the deeper half of the zone of vertical cells. The dendritic field is narrow and cylindrical, 100 to 250 micrometer in diameter, and extends from the upper margin of the zone of horizontal cells to the lower margin of the zone of vertical cells, about 500 micrometers. Rather than having superficial and deep fields, the pyramidal cell has the deep field reduced to a circumsomatic field, or a diminuitive basal field, and the superficial field is relatively elongated to accord with the deeper cell body. Pyramidal cells are usually multipolar, with one or two thick apical dendrites, which branch several times on the way to the surface, particularly in the upper portion of the zone of horizontal cells, and several smaller dendrites which form a small field about the cell body. It is of interest that smooth pyramidal cells tend to have two primary dendrites, like smooth vertical fusiform cells. The axon takes its origin from the soma or a low order dendrite and runs down into the deep zones. It is smooth and thin, about like that of the vertical fusiform cells. pyramidal cell Superior colliculus superficial gray layer
Colliculus superior stellate neuron The third major category of cells in the superior colliculus is the stellate cell. The cells are defined by the lack of overall orientation to the dendritic fields which extend symmetrically from the cell body. Stellate cells are multipolar with dendrites arising from any portion of the cell body. The dendrites may range anywhere from gnarled to radiate with the gnarled spiny cells most frequent in the zone of horizontal cells and the smooth radiate cells increasingly more frequent in the deeper zones until they are almost the only cell type in the zones below the stratum opticum. The dimensions of the cell bodies and dendritic fields are comparable to those of other cells in the same zone and the dendritic field is generally contained within the same zone as the cell body. The axons of stellate cells have both local and/or distant distributions and a morphology characteristic of intrinsic axons. As with all the other cell types, the axon may take its origin from the cell body or a low order dendrite. stellate neuron Superior colliculus
Colliculus superior type I ganglion cell Type I ganglion cells are the piriform cells. type I ganglion cell Superior colliculus
Colliculus superior wide field vertical cell There are two similar populations in the group of wide field vertical cells. The first lies in the deep margin of the zone of vertical cells where it looks very similar to the piriform cells relative to the zone of horizontal cells. Cajal called these the ovoid or triangular cells. The second population has its cell bodies distributed primarily to the upper portion of the zone of optic fibers. Cajal called these triangular or stellate cells. Cajal's nomenclature is rather bulky and, though descriptive, somewhat confusing because stellate cells are a distinct cell type in the nomenclature of this paper and triangular occurs in both names. For reasons developed below, the ovoid or triangular cells or wide field cells of the zone of vertical cells will be called Type II ganglion cells and the triangular or stellate cells or wide field cells of the zone of optic fibers will be called Type III ganglion cells. Type I ganglion cells are the piriform cells. Collator note: we assumed this class of neurons as projection neurons, because at least several subpopulations project to visually related areas. See Sefton et al., 2005; Mason and Groos, 1981; Mackay to Sim et al. 1983; Okoyama and Kudo, 1987). wide field vertical cell Superior colliculus

The axonal plexus can extend as much as 3.5mm along the septotemporal axis of the dentate gyrus.

Hippocampus CA1 lacunosum moleculare neuron CA1 Lacunosum-Moleculare (LM) interneurons are one of the inhibitory interneuron in the CA1 area. The L-M interneurons have been described as non-fast spiking cells (Kawaguchi and Hama, 1987) with membrane properties very different from those of pyramidal cells (Williams and Lacaille, 1993). Dendrites extend in the stratum lacunosum-moleculare, radiatum, and oriens and have a very wide extension in the transverse slice (Lacaille and Schwartzkroin, 1988a). The axonal arborization seems to cover a wide area in both transverse and longitudianal directions, projecting in stratum pyramidale and sometimes in the stratum oriens (Lacaille and Schwartzkroin, 1988a).

Hippocampus CA1 neurogliaform neuron CA1 neurogliaform neuron is a GABAergic interneuron, these cells are positive for NPY and co-express the actin-binding protein alpha-actinin-2. They are not positive for PV and VIP. Characteristically these neurons has a round cell body and short, non-spiny dendrites that were arranged in a stellate patterns around the cell body, spatially localized to the SLM, and often enter the molecular layer of the dentate gyrus. The axons are branched profusely close to soma occupying greater area than dendrites, like dendrites axons also tend to occupy mainly the SLM, often traveling fairly long distances along the SLM axis and mostly even entering the neighboring molecular layer of the dentate gyrus.

Neocortex Cajal-Retzius cell Neurons of the human embryonic marginal zone which display, as a salient feature, radial ascending processes that contact the pial surface, and a horizontal axon plexus located in the deep marginal zone. These cells were first described by Retzius (Retzius, 1893, 1894) (see the cell labelled 'Retzius, 1893' in Fig. 1). There is consensus that homologous elements are present in the non-primate neocortex, where their morphology is much simpler, as initially described in 1891 by Cajal (Fig. 2) (Cajal, 1891). \\nThe definition of these cells has remained somewhat confusing, in part because Cajal and Retzius studied different species and different developmental stages, and also because their original publications have not been generally available. Meyer et al (1999)prefer to define 'Cajal\\u2013Retzius cells' loosely, as the family of Reln-immunoreactive (ir) neurons in the marginal zone, and reserve the term of pioneer neurons for the early, Reln-negative preplate derivatives that settle in the MZ and project to sub-cortical levels.

Retina bistratified amacrine cell Collator note: bistratified amacrine cells are not explicitly defined by Perry and Walker. Perry and Walker describe three types of bistratified amacrine cells, having thef dendrites or spines distributed in two strata as the common character. bistratified amacrine cell
Retina cone cell One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, but they provide vision with higher spatial and temporal acuity, and the combination of signals from cones with different pigments allows color vision.

Retina ganglion cell A Large to bodied/large to field RGCs in the rat...Group RGA cells...have large somata (15 to 39 micrometers in diameter) and large, radially branching dendritic fields (235 to 748 micrometers in diameter), and many exhibit tracer coupling
Retina ganglion cell A1 Subgroup RGA1 cells (Figs. 2A, 3 to 5, Table 1) have a morphology similar to that of the giant cells of Bunt (1976). They have large somata, often polygonal in shape, from which a medium to to large to gauge axon emerges (Figs. 2A, 3). In one instance, a bifucarting axon was seen to exit the soma (see Fig. 3A). The large dendritic fields of RGA1 cells consist of three to seven stout dendrites that emerge radially from a centrally placed soma. The dendrites are smooth and overlap infrequently (Figs. 2, 3). RGA1 cells are found across the retina (Figs. 5, 6)and, on average, have the largest dendritic fields of all the RGCs labelled. RGA1 cells exhibited tracer coupling...they were strongly coupled to at least ten neurons (large to bodied gnalgion cells and some presumed amacrine cells to the latter gad very small somata and were found both the GCL and the INL; Fig.5). We classified cells with a large soma and a large dendritic field as RGA, cells with a small to to medium to sized soma and a small to to medium to sized dendritic field as RGB, and cells with a small to to medium to sized soma but a medium to to to large dendritic field RGC. Seventy five RGA cells were identified. RGA cells had an average soma diameter of 23.4 micrometers, an average dendritic to field diameter of 300.0 micrometers, and a radial pattern of branching. They are similar to Perry type I cells (Perry, 1979). retinal ganglion cell A1 Retina

Retina ganglion cell A2 Alpha ganglion cells, which were defined by Peichl (1989), were identified and termed RGA2 in the present study (see Table 1). The RGA2 cell has a large soma from which a thick axon emerges. Four to eight stout primary dendrites project radially from the cell body and branch repeatedly in a Y to shaped pattern. The dendrites branch at regular intervals, with the first branch point being within half of a soma diameter of the cell body. This branching pattern gives the appearance of a relatively uniform, medium density of dendrites across the dendritic arbor. The cell body is usually situated at the centre of the dendritic field. They stratify at ... 72 and plusmn; 15% of the IPL (inner) or 34 and plusmn; 10% of the IPL (outer). RGA2 cells had a round soma and 4 to 7 primary dendrites that branch repeatedly proximal to the soma. In contrast to the RGA1 cells, RGA2 cells have many more dendrites surrounding the soma (Fig. 3B). retinal ganglion cell A2
Retina ganglion cell A2 inner As Huxlin and Goodchild (1997), we identified two groups of RGA2 cells with dendrites stratifying in the inner and outer IPL (Table 1). They are morphologically similar to the outer alpha cells of Peichl (1989) and Tauchi et al. (1992). As Huxlin and Goodchild (1997), we identified two groups of RGA2 cells with dendrites stratifying in the inner and outer IPL (Table 1). They are morphologically similar to the outer alpha cells of Peichl (1989) and Tauchi et al. (1992). retinal ganglion cell A2 inner Retina

Retina ganglion cell B Sixty to eight neurons with small somata (12 to 24 micrometers in diameter), small dendritic fields (99 to 289 micrometers in diameter), and small axonal diameters (04. to 07. micrometers in diameter) make up Group RGB.We classified cells with a large soma and a large dendritic field as RGA, cells with a small to to medium to sized soma and a small to to medium to sized dendritic field as RGB, and cells with a small to to medium to sized soma but a medium to to to large dendritic field RGC.
Retina ganglion cell B1 Twenty to six neurons were defined as RGB1 cells (Fig. 8A, Table1). One of their characteristic features is the fact that the cell body always lies outside within the confines of the dendritic tree. They have the highest eccentricity of body relative to dendritic field of all ganglion cell identified. The majority of RGB1 cells analysed stratify diffusely within the IPL; nevertheless, their dendritic trees are centred in either the on to or the off to sublaminae of the IPL (Table 1). RGB1 cells were found across the retina. 1 cells had curvy but generally radially branching dendrites (Fig. 5A). They ramified in the outer IPL close to the middle. retinal ganglion cell B1 Retina
Ganglion cell layer
Retina ganglion cell B2 Fourteen neurons were defined as RGB2 cells (Figs. 2D, 8B). These cells are easy to distinguish by the very dense nature of their small dendritic trees. This high density is due to frequent, irregular branching of fine dendrites, which curve, twist, and overlap extensively (Fig. 2D). Their cell body is generaly located well within the confines of the dendritic tree. RGB2 cells were found across the retina (Fig. 9). RGB2 cells had a very small but very dense dendritic field (Fig. 5B), featuring numerous tiny branches bearing spines. They ramified almost in the middle of the IPL. retinal ganglion cell B2 Retina

Retina ganglion cell B3 Twenty to four cells were defined as RGB3 cells (Fig. 8C). The shape and branching patterns of their dendritic trees resemble those of RGA2 cells, although dendritic fields are much smaller. The somata are centrally located within the dendritic field. RGB3 cells show a greater range in dendritic field sizes than other RGB subgroups (Fig. 9), which suggests further heteronegeitiy. RGB3 cells had curvy, recursive dendrites, forming a relatively sparse dendritic field (Fig. 5C). retinal ganglion cell B3 Retina

Retina ganglion cell C Group RGC cells are defined as having small to to to medium cell bodies and medium to to to large dendritic fields. Their morphology was more heterogeneous than that of Groups RGA and RGB. We classified cells with a large soma and a large dendritic field as RGA, cells with a small to to medium to sized soma and a small to to medium to sized dendritic field as RGB, and cells with a small to to medium to sized soma but a medium to to to large dendritic field RGC.
Retina ganglion cell C others The Group RGc cells, as mentioned above, are a heterogeneous population: we labelled several neurons that could not be classified as RGC1 or RGC2. Includes previously described exmples of Type III or Class III cells (Perry, 1979, Dreher et al., 1985), with their small somata and, in some cases, very large dendritic fields. retinal ganglion cell C others Retina

Retina ganglion cell C1 Five RGc1 cells were labelled that have small somata and large asymmetrical dendritic fields (Figs. 10A, 12). Although only a small number of them were labelled, they resemble the medial terminal nucleus (MTN) to projecting cells described by Dann and Buhl (1987). Compared with neurons in Group RGA, RGC1 cells have smaller cell bodies, a higher density of dendritic branching, and usually asymmetrical dendritic fields. The RGC1 cells exhibited smooth, small caliber, recursive dendrites extending from large primary ones. Dendritic field was of medium density (Fig. 6A). The RGC1 stratified mostly in the inner IPL. Their morphology is very similar to the MTN to projecting cells characterized by Dann and Buhl (1987). retinal ganglion cell C1 Retina

Retina narrow-field bistratified amacrine cell The third type of cell in the wide to field unistratified class of amacrine cell has a distinct dendritic pattern. The mean soma size, 11.4 micrometers, is larger than the other two types range (10.0 to 13.0 micrometers; N = 10). Usually three but sometimes two large dendrites arise from the cell in the same layer as the soma. After a short distance a very fine branch comes off each of the larger branches, again in the same plane as the cell soma. narrow-field bistratified amacrine cell Retina

The somata of RBs are larger and are located in the outer half of the INL close to the OPL; their axons run through the OPL and end in large lobulated terminals at the border of the IPL and ganglion cell layer (Euler and Wassle, 1995). rod bipolar cell Retina inner nuclear layer

Retina wide field diffuse amacrine cell This cell type has a mean soma size of 10 micrometers (range 8.3 to 13.5 micrometers; N = 14). The extent of its dendritic field is difficult to define precisely; there is a core of short branches that extend vertically through the inner plexiform layer, and this core is surrounded by a number of branches that take an oblique course through the inner plexiform layer before terminating at variable distance from the cell soma at the level of ganglion cells. The dendrites of these cells have a characteristic varicose appearance and the ends of the dendrites often terminate with one of these swellings. Mihail Bota Retina

Retina wide-field bistratified amacrine cell These wide to field bistratified cells have a process that leaves the soma and passes almost vertically through the inner plexiform layer before branching near the ganglion cell layer, but in addition they also have processes that run laterally at the level of the inner nuclear layer. wide-field bistratified amacrine cell Retina

Retinal ganglion cell C2 RGC2 gave a morphology similar to the delta ganglion cells of Peichl (1989). They have a small to medium to sized somata from which fine axons emerge. Two to four primary dendrites branch close to the soma. These and subsequent branches twist and turn, unlike the radiating dendrites of the Group RGA neurons. The soma is usually central to the dendritic field. The dendritic fileds are smalled than those Group RGA cells at the same eccentricities, and they show little variation in size as a function of eccentricity (Fig. 12). RGC2 neurons did not exhibit tracer coupling, but many have numerous and prominent dendritic spines. The RGC2 cells had a similar morphology to RGC1 cells but with curvier dendrites and a denser dendritic field (Fig. 6B). retinal ganglion cell C2

Superior colliculus type II ganglion cell The Type II ganglion cells, like the piriform cells, have all or almost all of their dendritic field superficial to the cell body. The 15 to 25 micrometers cell body lies within a narrow range of depths at the deep margin of the zone of vertical cells from which it may send 3 to 7 primary dendrites vertically or obliquely towards the surface to form a dendritic field in excess of 400 micrometers in diameter and about 500 micrometers deep. The primary dendrites may derive from any portion of the cell body surface, but they usually arise from the dorsal or lateral surfaces. The dendrites of Type II ganglion cells intermingle, giving them a dense arbor of dendrites that extend over large regions of the superior colliculus. The axon may originate from the cell body or a low order dendrite. It may project into the region superficial to the cell body (figs. 9, 14) or into the deep zones (fig. 15). The axon of the superficial projection is similar to other intrinsic axons except for being thicker. It branches frequently to form an arbor approximately as wide as the dendritic field, which it overlaps, but they are not necessarily coincident, nor is one contained within the other. type II ganglion cell
Superior colliculus type III ganglion cell The Type III ganglion cells resemble Type II ganglion cells in most respects. They are multipolar with 3 4 primary dendrites, a cell body 20 to 25 micrometers in major diameter, and a dendritic field which may be more than 1000 micrometers in diameter. They differ in that some of their dendrites extend below the cell body and their cell bodies lie in the zone of optic fibers. The axon almost invariably runs down into the deep portion of the colliculus. Type III ganglion cells tend to have fewer, but thicker, dendrites passing through the first two zones than is usual for Type II ganglion cells. The dendrites are less spiny, branch less often, but like the other types of ganglion cells, they break up into many fine branches as they approach the surface, particularly in the upper portion of the zone of horizontal cells. type III ganglion cell
