Brain study: Motor cortex contributes to word comprehension

Researchers have experimentally confirmed the hypothesis, whereby comprehension of a word’s meaning involves not only the ‘classic’ language brain centers but also the cortical regions responsible for the control of body muscles, such as hand movements. The resulting brain representations are, therefore, distributed across a network of locations involving both areas specialized for language processing and those responsible for the control of the associated action….
