Abstract

To determine the difference of size between the cortical speech region in the dominant hemisphere and its corresponding region in the other hemisphere, the planum temporale was measured and compared by means of a rubbed copy method using 50 brains of both sexes. The planum temporale was significantly larger in the left hemisphere than in the right.
