title: Central nervous system neurons identified after injection of pseudorabies virus into the rat clitoris.
abstract: Transneuronal tracing techniques were used to identify putative spinal and brain neurons involved in the efferent control of the clitoris. Pseudorabies virus was injected into the rat clitoris and virus-labeled neurons were identified immunohistochemically. Neurons were found primarily in L5-S1 segments of the spinal cord. In addition, virus-labeled cells were found in T12-L4 and S2-S4. In the brain, virus-labeled cells were found in the nucleus paragigantocellularis, raphe pallidus, raphe magnus, Barrington's nucleus, ventrolateral central gray, hypothalamus and medial pre-optic region. These data identify a multisynaptic circuit of neurons which may be involved in clitoral control.
