| glia | <pathology> Supportive tissue of the brain. There are three types of glial tissue: astrocytes, oligodendrocytes and microglia. Glial cells do not conduct electrical impulses, as opposed to neurons. (16 Dec 1997) |

| cell adhesion molecules, neuron-glia | Cell adhesion molecules that mediate neuron-neuron adhesion and neuron-astrocyte adhesion. They are expressed on neurons and schwann cells, but not astrocytes and are involved in neuronal migration, neurite fasciculation, and outgrowth. Ng-cam is immunologically and structurally distinct from ncam (neural cell adhesion molecules). (12 Dec 1998) |
| Bergmann, Gottleib | <person> German neurologist and anatomist, 1781-1861. See: Bergmann's cords, Bergmann's fibres. (05 Mar 2000) |
| Bergmann's cords | Slender fascicles of fibres extending transversally below the ependymal floor of the ventricle from the median sulcus to enter the inferior cerebellar peduncle. They arise from the arcuate nuclei on the ventral surface of the medullary pyramid. Synonym: striae medullares ventriculi quarti, acoustic striae, auditory striae, Bergmann's cords, medullary teniae, teniae acusticae. (05 Mar 2000) |
| Bergmann's fibres | Filamentous glia fibre's traversing the cerebellar cortex perpendicular to the surface. (05 Mar 2000) |
