Fig. 7.

Tonotopic organization in the auditory cortex. Two, stronger, tonotopic gradients from low- (L) to high-frequency (H) encoding auditory information are present in the rostral (rHG) and caudal Heschl’s gyrus (cHG), forming a “V” shape, and a third, weaker, tonotopic gradient is present in the planum temporale (PT) [38, 39]. The above slice is shown from a top-down view of the superior-temporal plane depicted in the bottom-right corner. Figure reused with permission from Ref. [39]
