The Language Faculty, Broca'S Region, and the Mirror System

Examples of three types of empirical arguments are given for the modularity of language mechanisms in Broca's region, and against a unified account of the functional role of this region and of the ventral precentral sulcus (vPCS). These are (a) pure syntactic considerations, (b) observations on the comprehension performance of Broca's aphasics, (c) recent fMRI results from receptive tasks at the sentence level.
