The planum temporale is the cortical area just posterior to the auditory cortex (Heschl’s gyrus) within the Sylvian fissure. It is a triangular region which forms the heart of Wernicke’s area one of the most important functional areas for language. Original studies on this area found that the planum temporale was one of the most asymmetric regions in the brain with this area being up to ten times larger in the left cerebral hemisphere than the right.
