New research from an international team of researchers, including as lead author Dr Alexandra Woolgar of the department of Cognitive Science, suggests that the language system in the brain is not necessarily essential for complex thought and planning.

The ability to think flexibly and to solve novel problems (known as fluid intelligence) is proposed to depend upon a set of frontal and parietal ‘multiple-demand’ (MD) brain regions.

In a study published today in Nature Human Behaviour, the team found that the extent of damage to the MD-system predicted fluid intelligence loss after brain injury, whereas damage to the language system did not.
