[Efferent projections of the ventral portion of the putamen to the frontal, parietal and temporal regions of the cat cerebral cortex]

Abstract

Following the electrolytic lesion of putamen (rostral and caudal parts of the ventral field) of the cat's brain, degenerating endings of axons in the cerebral cortex were revealed ipsi and heterolaterally in frontal sections of the brain impregnated after Nauta--Gygax and Wiitanen. The projections were organized topically: the rostal part of putamen was projected to anterior parts of the cortex (motor and premotor, orbito-insular and S zones), while the caudal part sended the fibres to the occipital and auditory fields of the cortex and S2 zone.
