Medial preoptic neuronal responses to connatural females in sexually inactive male monkeys (Macaca fuscata).
Neuronal responses to a connatural female were investigated in the medial preoptic area of two sexually inactive male monkeys. Of 72 neurons tested, the presence of the female elicited a phasic excitatory response in 11 neurons and a tonic excitatory response in 5 neurons. These findings suggest that a small number of medial preoptic neurons are involved in coding the presence of the female in the sexually inactive male monkey.
