Fiber connections between the thalamic posterior lateral nucleus and the cingulate gyrus in the cat

Wheat germ agglutinin and horseradish peroxidase conjugate (WGA-HRP) was injected into the anterior part of the cat cingular area as designated by Rose and Woolsey. This produced ipsilaterally numerous labeled neurons and fibers in the lateral marginal band of the rostral part of the thalamic posterior lateral nucleus (LP), where hypothalamic afferents terminate. Other fiber connections with the thalamic intralaminar and midline nuclei suggest that the anterior part of the cingular area corresponds with the anterior cingulate gyrus of the primate.
