The cerebellum is an important contributor to the neural basis of sexual behavior, but the specific cerebellar regions underlying different aspects of reproduction are still unknown. Here, we used experimental lesions of Lobules VIa and VII of the vermis to investigate their specific role, both in locomotion stimulated by sexual cues and the execution of sexual behavior. Sexually experienced male rats and receptive females were used, and experimental males received an electrolytic lesion of either lobule. Before and after the lesion, males were tested for sexual behavior, and for locomotion on a horizontal or ascending bar to reach an estrous female. The lesion of Lobule VIa produced impairments in intromission-related behaviors during copulation, and produced slippery footsteps that increased the time to cross the bars with a stronger effect on the ascending bar. The lesion of Lobule VII produced a dramatic arrest of respiration that precluded further behavioral tests. These results suggested that Lobule VIa is involved in the integration of sensory inputs coming from in-copula penile stimulation, implying the existence of a penis-cerebellum neural pathway for a proprioception-like process involved in the proper spatial orientation of the erected penis. Walking on bars showed an alteration of the stepping cycle that suggests the role of Lobule VIa in the fine tuning of locomotion spinal reflexes. The lesion of Lobule VII suggested its role in the physiology of respiration, a topic that deserves further research. [-]
