Abstract:
Topographical Projections of cingulate cortex to the central lateral nucleus (CL) of thalamus in the cat was observed by means of retrograte HRP technique. After injection of HRP into rostral part of the CL, labeled cells were mainly distributed in ipsilateral anterior cingulate cortex. A few cells were also labeled in the corresponding location of the contralateral cingulate cortex. Following injections of HRP into caudal part of CL, the HRP-positive neurons were found in both anterior and posterior parts of the cingulate cortex ipsilaterally, the labeled cells were considerable sparser than in rostral injection cases. Labeled cell in all cases were located in inferior part of lamina Ⅴ and lamina Ⅵ. They are small to middle sized pyramidal neurons. These results suggest that the cingulate- CL projection are topographically organized.
