In the present study we examined the distribution pattern of serotonin
(2A) (5-HT2A) receptors in the rat cerebellum. A strong immunoreaction
against 5-HT2A receptor protein was observed in Purkinje cells. A den
se cluster of immunopositive dendritic profiles of Purkinje cells was
located beneath the pia matter of cerebellar cortex. Somal profiles in
the cerebellar nuclei had weak to moderate immunoreactions. (C) 1998
