Serotonergic modulation of evoked responses in turtle cerebellar Purkinje cells.


1. Immunocytochemical studies of the turtle brain revealed the presence of serotonin (5-hydroxytryptamine, 5-HT) immunoreactive (5-HT-ir) processes in the granule and Purkinje cell layers, but not in the molecular layer (ML), of the cerebellar cortex. Immunoreactive axonal profiles were present throughout the granule cell layer (GCL) where they generally… (More)
