The sulci of the cuneus of the human cerebrum.
The limiting and internal sulci of the cuneus of the occipital lobe of 80 cerebri of Brazilians of either sex (24 females and 56 males) were studied and findings were correlated with each hemisphere and the sex of the individuals. The distribution of the material was 39 Caucasians (11 females and 18 males) and 41 non-Caucasians (13 females and 28 males). The limiting sulci, namely parieto-occipital and calcarine, were found in all cases. The internal sulci were classified in horizontal, oblique, vertical and cuneolingual. The cuneus of the right cerebral hemisphere had more sulci than that of the left. The cuneus had also more sulci in males than in females.
