Afferent connections to the pontine nuclei from the cortex of the anterior ectosylvian sulcus in the cat.
Following injections of horseradish peroxidase conjugated with wheatgerm agglutinin (HRP-WGA) in different sectors of the cortex of the anterior ectosylvian sulcus (SEsA), anterograde labeling was observed in the pontine nuclei (PN) of the cat. Labeled fibers were identified in a wide area which covers the entire rostro-caudal extent of the PN. The various sectors of the SEsA, which differ in their associative, cortico-cortical connections with the somatosensory, auditory and visual cortices, also were shown to differ in their projection patterns to the PN. These corticopontine projections of the SEsA were compared to those from the modality specific areas.
