Effect of stimulation of the putamen on the substantia nigra in the cat.
The function of the putamen has been investigated in the cat by stimulating the nucleus electrically and recording from neurons of the pars reticulata of the substantia nigra. It was found that putaminonigral fibers were, at least partly, inhibitory in nature and that they exerted this inhibition monosynaptically on nigral neurons.
