From Hearing Sounds to Recognizing Phonemes: Primary Auditory Cortex is A Truly Perceptual Language Area. Brodmann areas 41/42 phonological perception word-deafness language understanding Wernicke’s areaĬitation: Byron Bernal, Alfredo Ardila.BA41/42 are primary auditory cortices harboring complex phoneme perception functions with asymmetrical expression, making it possible to include them as core language processing areas (Wernicke’s area). ![]() Phonological processing may take place in either the right or left side, but customarily the left exerts an inhibitory tone over the right, gaining dominance in function. BA41, and to a lesser extent BA42, are involved in early stages of phonological processing (phoneme recognition). Damage in the PAC is associated with so-called “pure word-deafness” (“auditory verbal agnosia”). Nonetheless, the PAC shows specific sensitivity to speech. PAC activates with a plethora of diverse basic stimuli including but not limited to tones, chords, natural sounds, consonants, and speech. The aim of this article is to present a systematic review about the anatomy, function, connectivity, and functional activation of the primary auditory cortex (PAC) (Brodmann areas 41/42) when involved in language paradigms. ![]()
