N2 - In order to study the corticothalamic projec­tions, injections of horseradishperoxidase and fluorochrome tracers were made in medial, intralaminar and anterior thalamic nuclei and the habenular complexo The mediodorsal tha­ lamic nucleus is the nucleus receiving the most important number of projections from both hemispheres. The ratio between the amount of the retrograde cell labeling in layer V and VI was slightly greater in the contralateral than in the ipsilateral hemisphere in the case of the intermediate band of mediodorsal .nucleus. Lamina VI connects more abundantly than layer V to the rostral intralaminar nuclei. The centro­ median-parafascicular complex, the midline tha­ lamic nuclei and habenula receive more projec­tions from layer V. The anterior thalamic complex receive similar proportion of projections from layer V and VI of the cortex. ER -
