The cerebellum is generally considered a neural structure specialized in motor control and recent imaging
data suggest its role in sexual behavior. Herein, we analyzed the pattern of Fos immunoreactivity (Fos-IR) in
the cerebellum of female rats allowed to pace copulation as a model of sexual reward in rodents.
Ovariectomized, hormone-primed, sexually naïve females formed three groups: Pacing, Nonpacing and
Control. Pacing occurred in arenas bisected by a middle divider that allowed only females to control sexual
interaction with stud males. For nonpaced copulation the divider was removed, and control females were
allowed to pace in chambers without a male. Fos-IR was analyzed in granule and Purkinje layers of the 10
cerebellar lobules, and in the fastigial deep nucleus (FDN). Results indicated that Pacing females expressed
more Fos-IR in the granule layer compared to Nonpacing and Controls, and more Fos-IR in Purkinje compared
to Nonpacing. No differences were observed in FDN. Such response cannot be explained with motor activity
because Pacing females moved less in general. We discuss the role of the cerebellum and its connections in the
sexual reward induced by pacing. [-]
