abstract = {There is a considerable contrast between the various
functions assigned to Broca's region and its relatively
simple subdivision into two cytoarchitectonic areas (44 and
45). Since the regional distribution of transmitter
receptors in the cerebral cortex has been proven a powerful
indicator of functional diversity, the subdivision of
Broca's region was analyzed here using a multireceptor
approach. The distribution patterns of six receptor types
using in vitro receptor autoradiography revealed previously
unknown areas: a ventral precentral transitional cortex 6r1,
dorsal and ventral areas 44d and 44v, anterior and posterior
areas 45a and 45p, and areas op8 and op9 in the frontal
operculum. A significant lateralization of receptors was
demonstrated with respect to the cholinergic M(2) receptor,
particularly in area 44v+d. We propose a new concept of the
anterior language region, which elucidates the relation
between premotor cortex, prefrontal cortex, and Broca's
region. It offers human brain homologues to the recently
described subdivision of area 45, and the segregation of the
ventral premotor cortex in macaque brains. The results
provide a novel structural basis of the organization of
language regions in the brain.},
