Electrophysiological evidence for branching nigral projections to pontine reticular formation, superior colliculus and thalamus.
Neurons of the pars reticulata of the substantia nigra were activated antidromically by stimulating pontine reticular formation, superior colliculus and thalamus. Many nigral neurons (42.6%) were activated antidromically from pontine reticular formation ipsilaterally and about a half of them had branching axons to superior colliculus and/or thalamus.
