University of California - Berkeley study finds depth of small grooves in brain's surface linked to stronger network connectivity and better reasoning ability.

The depths of some of the smallest of these grooves seem to be linked to increased interconnectedness in the brain.

The grooves may actually bring those areas closer together in space, shortening the connections between them and speeding communications.

UC Berkeley researchers identify tertiary sulci in the front of the brain behind the forehead.

The longer the sulcus, the better a person was at processing and recognizing human faces, they say.

In a new study, Weiner , Bunge and their colleagues painstakingly catalogued the tertiary sulci in lateral parietal cortex.
