The cortical projections of the thalamic intralaminar nuclei restudied by means of the HRP retrograde axonal transport.
Following multiple injections of HRP in different cortical areas in the cat, labeled cells were, in some cases, found in the thalamic intralaminar nuclei. The following cortical zones were found to constitute the preferential target for the projections from the respective intralaminar nuclei: motor and anterior suprasylvian areas for the nucleus centralis lateralis, cingulate cortex for the nuclei paracentralis and centralis medialis, sensory and motor areas for the nucleus centrum medianum. These data are compared with the results previously obtained by means of the retrograde degeneration technique.
