Abstract:
The afferent and efferent connections of middle suprasylvian gyrus (MSS) were studied in 18 cats by means of anterograde and retrograde transport of horseradish peroxidase (HRP). 0.1～0.4?l of saline solution containing 50％ HRP and 2％ DMSO (dimethylsulfoxide) was injected into the cortical areas (areas 5, 7, LS, 21, 19) of MSS according to the map of Heath and Jones (1971). The frozen sections were processed with TMB method. Each cortical area of MSS has reciprocal connections with ipsilateral pulvinar (PUL), lateral posterior nucleus (LP) and posterior nucleus (PN) of the lateral nuclear group of thalamus and central medial nucleus (NCM), paracentral nucleus (PC) and central lateral nucleus (CL) of the intralaminar nuclear group. The cortical areas in rostral part of MSS have additional connections with posterior nuclear group (PO), central median nucleus (CM), parafascicular nucleus (PF), ventral anterior nucleus (VA) and ventral lateral nucleus (VL). Labeled terminals are more packed in lateral nuclear group than in intralaminar nuclear group. In nuclear reticularis (R), zona incerta (ZI) and ventral nucleus of lateral geniculate body (GLv) only labeled terminals could be found.In addition, labeled terminals were found in caudate nucleus, putamen, pretecrum, colliculus superior and nuclei pontis and labeled cells could be seen in locus caeruleus, amygdala and nuclei raphe. Both labeled cells and terminals were present in claustrum bilaterally, but notably ipsilaterally.
