Accumbens Nucleus of CIVM postnatal rat brain atlas +he accumbens nucleus forms the major part he accumbens nucleus forms the major part of the ventral striatum; however, it has a unique appearance on MRI that makes it relatively easy to segment as a distinct structure from the rest of the ventral striatum. This nucleus is most easily segmented in the coronal plane of a diffusion-weighted image (DWI). The rostral border is defined by a low diffusivity (bright on DWI) region just dorsal and medial to the anterior limb of the anterior commissure. More caudally the accumbens becomes a large circular region that completely surrounds the anterior limb of the anterior commissure. The ventral border is defined by the rostral aspect of the ventral pallidum, which appears as a horizontal line of dark (high diffusion) spots on DWI. The dorsal border between the accumbens and the rest of the striatum can be identified based on the start of the dark striations that define the caudate/putamen. The caudal extent of the accumbens ends just rostral to the decussation of the anterior commissure. In general, the accumbens is brighter on DWI (lower diffusion) than surrounding tissue. (lower diffusion) than surrounding tissue.
Anterior olfactory nucleus +The structure can be found behind the olfa The structure can be found behind the olfactory bulb in all vertebrates. Since in many primates the bulb is located at the end of a long stalk below the frontal cortex, the AON is often difficult to locate and may appear only as islands of cells in the stalk rather than a clearly defined ring. In the macaque monkey, it may be as small as only twelve cells in some cross-sections. only twelve cells in some cross-sections.
Anterior perforated substance +Lies on the basal surface and bounded by t Lies on the basal surface and bounded by the olfactory trigone rostrally, the diagonal band medially and caudally and the prepiriform cortex laterally. It is characterized by many perforations caused by small blood vessels entering the gray matter (Meyer et al., J. Comp. Neurol 284: 405, 1989). r et al., J. Comp. Neurol 284: 405, 1989).


Bed nucleus of the stria medullaris +at the level where the stria medullaris an at the level where the stria medullaris and fornix lie adjacent to one another, these cells are more abundant and form an obvious, compact cell group that appears encapsulated between the two fiber tracts rostrally, but then appears embedded among myelinated axons of the stria medullaris caudally. ed axons of the stria medullaris caudally.


CA1 of RHA11 +Bounded by CA2, Fasciola and Subiculum
CA2 of RHA11 +Bounded by CA1 and CA3
CA3 of RHA11 +Bounded by CA2 and dentate gyrus
Caudal entorhinal field of RHA11 +Bounded by the dorsal intermediate entorhinal area, dorsolateral entorhinal area, medial entorhinal area and ventral intermediate entorhinal area
Caudomedial lobule +Bordered ventrally in the macaque by the anterior calcarine fissure
Cerebrospinal axis +lies in the medial plane of the body dorsal to the notochord
Cingulo-parahippocampal isthmus of DMVH2003 +In horizontal-oblique planes perpendicular In horizontal-oblique planes perpendicular to the long axis of the isthmus, appears as a roughly C-shaped bulge of cortex. In gross preparations, the anterior surface is blocked from view by the thalamus and brainstem, while the medial and posterior surfaces are covered by the lower bank of the anterior calcarine fissure. The anterior part borders the posterior subiculum laterally (see Fig. 3). osterior subiculum laterally (see Fig. 3).


Entorhinal cortex of RHA11 +Anteriorly, the entorhinal cortex is flank Anteriorly, the entorhinal cortex is flanked by the piriform cortex laterally, and by the periamygdaloid cortex and the posterior cortical nucleus of the amygdala, medially (non-hippocampal regions not further described in this atlas). The transition between the entorhinal cortex and its anterior neighbors is approximately at the midst of the amygdaloid fissure, where the entorhinal cortex progressively decreases in width, such that it eventually extends anteriorly for approximately 2 mm as a narrow strip. This anterior extension is delimited dorsolaterally by the perirhinal cortex and ventromedially by the piriform cortex. At its laterocaudal site, the entorhinal cortex is surrounded by the perirhinal and postrhinal cortices. Medially, the entorhinal cortex is bordered over most of its rostrocaudal extent by the parasubiculum. rostrocaudal extent by the parasubiculum.


Frontal operculum +The frontal operculum is demarcated caudal The frontal operculum is demarcated caudally from the ventral precentral gyrus by the inferior precentral sulcus, dorsally from the middle frontal gyrus by the inferior frontal sulcus, and rostrally from the pars triangularis by the anterior ascending ramus of the Sylvian fissure ior ascending ramus of the Sylvian fissure


Inferior frontal gyrus +Component of the frontal lobe, lateral asp Component of the frontal lobe, lateral aspect. The rostral boundary is the first appearance of the inferior frontal sulcus whereas the caudal boundary is the precentral gyrus. The medial and lateral boundaries are the lateral bank of the inferior frontal sulcus and the medial bank of the lateral orbital sulcus and/or the circular insular sulcus respectively (Christein Fennema-Notestine). espectively (Christein Fennema-Notestine).
Inferior pulvinar nucleus +located ventrally between the medial and lateral geniculate bodies
Insula +Buried in lateral sulcus, covered by opercular parts of frontal, parietal, and temporal lobes
Isla magna of Calleja +Located at the interface of the nucleus accumbens, the lateral septal nucleus and the diagonal band


Lateral paragigantocellular nucleus +DiI injection in fetal humans; projection statements based on Table 1.


MP2009 extreme capsule +Comparison of external capsule fibers with the adjacent middle longitudinal fascicle in the same subjects reveals that EmC is located in a medial and rostral position relative to MdLF flanking in part the medial wall of the insula.
Medial geniculate body +Found medially to the lateral geniculate body in humans and ventral to it in cats, intercalated between the fibers of the brachium of the inferior colliculus and those of the auditory radiation.
Middle temporal area +located on the "caudal third of the middle temporal gyrus."
Middle temporal area (Rhesus macaque) +posterior bank of the superior temporal sulcus


Nucleus paramedianus dorsalis +located adjacent and medial to the nucleus prepositus in the dorsal medulla; it begins at about the same A-P level as nucleus prepositus hypoglossi, just rostral to the hypoglossal nucleus
