The smallest grooves on the brain's surface, unique to humans, have largely been ignored by anatomists, but recent studies show that they're related to cognitive performance, including face recognition and reasoning ability. A new study shows that the depths of these tertiary sulci are also linked to increased interconnectedness between areas of the brain associated with reasoning and high-level cognitive functions. The sulci may decrease the length of neural connections, improving communication efficiency.
