New Understanding of How the Brain Processes and Stores Words We Hear

[Source: Science Daily]

Georgetown University Medical Center neuroscientists say the brain’s auditory lexicon, a catalog of verbal language, is actually located in the front of the primary auditory cortex, not in back of it — a finding that upends a century-long understanding of this area of the brain. The new understanding matters because it may impact recovery and rehabilitation following a brain injury such as a stroke.

The findings appear in Neurobiology of Language on July 5, 2023.

Riesenhuber’s lab showed the existence of a lexicon for written words at the base of the brain’s left hemisphere in a region known as the Visual Word Form Area (VWFA) and subsequently determined that newly learned written words are added to the VWFA. The present study sought to test whether a similar lexicon existed for spoken words in the so-called Auditory Word Form Area (AWFA), located anterior to primary auditory cortex.
