Rexed lamina VII
| Name: | Rexed lamina VII |
| Description: | Lamina corresponding to the intermediate zone of the spinal cord and to parts of the ventral horn not occupied by lamina VIII and IX (Paxinos, The rat nervous system, 2nd ed, page 44. Lies adjacent to lamina VI, when VI is present; otherwise borders V. |
| Super-category: | Rexed spinal cord parcellation scheme region |
| Id: | nlx_143981 |
| Defining criteria: | cyto-architecture |

| Defining Criteria: | cyto-architecture |
| Cyto-architecture defining Criteria: | Lamina VII has a lighter and more homogeneous appearance in Nissl stained sections compared to the adjacent lamina (Paxinos, The rat nervous system, 2nd ed, pg 44).
From Rexed: "The medial boundary towards the region around the central canal is difficult to fix. In the sections its nerve cells are evenly distributed and rather uniform in size and general appearance. Ventrally the boundary of the 7th layer varies in different regions of the cord. In the intumescences the strong development of the lateral motor nuclei, forming layer IX, seems to have made these nuclei move more laterally and dorsally, and regions of nerve cells exactly like those of layer VII are seen to penetrate medial to these nuclei, even down to the ventral contour of the ventral horn." |
| Brain regions that receive axons from this region: | cerebellum |
| Overlaps : | intermediolateral nucleus, Clarke's Nucleus, central cervical nucleus |
