Scan Reveals How 'Brain Dictionary' Stores Thousands Of Words

3D Brain Dictionary To Help Decode Our Inner Thoughts.

New research has revealed that the brain uses a highly organised archiving system for language, where words are grouped by related meaning and context (pictured). Scientists at the University of California, Berkeley produced an atlas pinpointing where in the brain definitions of individual words are stored, illustrating the brain's semantic system in stunning detail 

The brain dictionary

For understanding language, this is called the semantic system and was believed to be largely based near the back of the brain.

In order to focus in on the semantic system, and to explore how the brain accesses definitions, scientists at the University of California, Berkeley recorded brain activity of volunteers as they listened to narrative stories.

Where exactly are the words in your head? 

Scientists have created an interactive map showing which brain areas respond to hearing different words. The map reveals how language is spread throughout the cortex and across both hemispheres, showing groups of words clustered together by meaning. 

The beautiful interactive model allows us to explore the complex organisation of the enormous dictionaries in our heads.
