THE FIBER CONNECTION OF RAT'S CINGULATE GYRUS——PROJECTION FROM THE THALAMUS AND MESENCEPHALON / 解剖学报

ABSTRACT

The projection from the thalamus and mesencephalon to the cingulate gyrus in the rat was studied with the horeseradish peroxidase method. Results were as followsWhen injections were made into the anterior part of the cingulate gyrus, the labeled cells were found mainly in the thalamic nuclei (AM, MD, LD) and the midbrain nuclei (SNC, AVT, nuclei raphe dorsalis and centeralis superior). When injection was made into the posterior part of the cingulate gyrus, a considerable number of HRP-positive neurons were seen in the laterodorsal nucleus (LD), mediodorsal nucleus (MD) and anterior thalamic nuclei (AM, AV, AD).When the injection was made into one side of the cingulate gyri, all labeled cells were found in the ipsilateral side, indicating the projection is uncrossed.
