Where the knowledge is hidden: More information on how our brain collects and stores knowledge

Have you ever wondered in which part of your brain all your knowledge lies?

A groundbreaking study by neuroscientists at Georgetown University Medical Center has challenged a century-old understanding of the brain's auditory lexicon, the catalog of verbal language. 

Let's find out more!

It's not where we expected it to be

Contrary to previous beliefs, the study reveals that the auditory lexicon is located in the front of the primary auditory cortex, not in the back. 

This finding could have significant implications for recovery and rehabilitation following brain injuries like strokes. 

The study, published in Neurobiology of Language, highlights the existence of an Auditory Word Form Area (AWFA) anterior to the primary auditory cortex, suggesting a new target area to comprehend speech comprehension deficits. 

Using functional magnetic resonance imaging (fMRI), researchers examined the spoken word processing abilities of 25 volunteers, employing a technique called functional-MRI rapid adaptation (fMRI-RA). 

It can help people with brain damage

Future studies aim to explore interventions targeting the AWFA and investigate the interaction between written and spoken word systems. 

Additionally, researchers hope to delve deeper into understanding how the brain processes words and how it utilizes auditory feedback in speech production and language learning processes.
