Evolutionary neuroanatomical expansion of Broca's region serving a human-specific function

This article presents an evolutionary neuroanatomical framework which may offer a solution to this dispute. It is proposed that in humans, Broca's region houses language and action independently in spatially separated subregions. This became possible due to an evolutionary expansion of Broca's region in the human brain, which was not paralleled by a similar expansion in the chimpanzee's brain, providing additional space needed for the neural representation of language in humans.PMID:37596132 | DOI:10.1016/j.tins.2023.07.004
