The human superior temporal gyrus is critical for extracting meaningful linguistic features from acoustic speech inputs. Local neural populations are tuned to acoustic-phonetic features of all consonants and vowels, as well as dynamic cues for intonational pitch. These populations are embedded throughout broader functional zones that are sensitive to amplitude-based temporal cues for prosody. Together, the distributed feature selectivity for phonetic and prosodic cues have generated a new and granular map of temporal cortex function. Beyond speech features, cortical representations are strongly modulated by learned knowledge and perceptual goals. I will review emerging insights on the remarkable emergent phonological computations that take place in this cortical region at the core of Wernicke’s area.
