Abstract

Efferent cortical connections of the cingulate gyrus are investigated in rhesus monkey using autoradiographic technique. The results indicate that the rostralmost part of the cingulate gyrus (area 32) sends projections to the lateral prefrontal and midorbitofrontal cortex and to the rostral portion of the superior temporal gyrus. In contrast, the other two major subdivisions of the cingulate gyrus, areas 24 and 23, have widespread connections within the cortex. Area 24, for example, projects to the pre-motor region (areas 6 and 8), the fronto-orbital cortex (area 12), the rostral part of the inferior parietal lobule, the anterior insular cortex, the perirhinal area and the laterobasal nucleus of amygdala. Area 23, likewise, sends its connections to the dorsal prefrontal cortex (areas 9 and 10), the rostral orbital cortex (area 11), the parieto-temporal cortex (posterior part of the inferior parietal lobule and the superior temporal sulcus), the parahippocampal gyrus (areas TH and TF), the retrosplenial region and the presubiculum. It seems that the connections of the rostralmost part of the cingulate gyrus resemble the efferent cortical connectional patterns described for lateral prefrontal and orbito-frontal cortex, whereas the projections of areas 24 and 23 are directed to the neocortical, the paralimbic and the limbic areas.
