WebAug 1, 2003 · They may represent ectopic granule cells; alternatively, they may represent a hitherto unknown population of cerebellar cells. In vitro experiments suggest that NeuN expression is related closely to granule cell axogenesis. This approach also revealed that the level of NeuN expression could be modulated by chronically depolarizing these cells. Cerebellar granule cells form the thick granular layer of the cerebellar cortex and are among the smallest neurons in the brain.
