Morphology and laminar distribution of cortico-claustral neurons in different areas of the rabbit cerebral cortex

This study examines the morphology and laminar distribution of cortico- claustral neurons that were retrogradely labelled after single injections of biotinylated dextran amine in the caudal two thirds of the rabbit insular claustrum. Labelled neurons were studied in neocortical areas 17, 18, and A2, insular cortex and cingulate areas 24a,b and 29b,c,d. Most of the labelled neurons lay in layer VI for area 17 and in layer V for the remaining...
