FIG 2. Photographs of the lateral surface of a cerebral hemisphere show stages in the dissection of the temporal lobe.
A, Initially, the white matter of the anterior part of superior temporal gyrus (small arrow) and temporal lobe pole (large arrow) was isolated by progressive removal of the gray matter.
B, With further dissection, the white matter of the anterior segment of the middle temporal gyrus (arrows) was isolated by progressive removal of the gray matter.
C, To visualize the insular gyri (small white arrows) covered by the middle cerebral artery (arrowhead) and its insular branches, the white matter of the anterior segment of the superior temporal gyrus was completely removed by dissection. A portion of the white matter of the middle temporal gyrus (black arrows) was also removed by dissection. The inferior temporal gyrus (large white arrow) was left intact.
