In the ventrolateral frontal lobe of the human brain there is a distinct entity, cytoarchitectonic area 44 (Broca's area), which is crucial in speech production. There has been controversy over whether monkeys possess an area comparable to human area 44. We have addressed this question in the macaque monkey by combining quantitative architectonic analysis of the cortical areas within the ventrolateral frontal region with electrophysiological recording of neuron activity and electrical… Expand
Cortico-cortical connections of areas 44 and 45B in the macaque monkey
TLDR
The results have provided a clarification of the relative connections of areas 44 and 45B of the ventrolateral frontal region which, in the human brain, subserves certain aspects of language processing. Expand
The mirror neuron system and the strange case of Broca's area
TLDR
The results show that Broca's area is minimally involved in action observation and has no motor output on hand or phonoarticulatory muscles, challenging its inclusion in the Mirror Neuron System, suggesting that the MNS may be involved in the representation of articulatory rather than semantic components of speech.

Distinct Parietal and Temporal Connectivity Profiles of Ventrolateral Frontal Areas Involved in Language Production
TLDR
A resting-state functional connectivity study provides a major improvement in understanding the connectivity of the areas in the ventrolateral frontal region that are involved in language production. Expand
Communicative Signaling Activates ‘Broca's’ Homolog in Chimpanzees
TLDR
Findings here are the first to provide direct evidence of the neuroanatomical structures associated with the production of communicative behaviors in chimpanzees and suggest that the neurological substrates underlying language production in the human brain may have been present in the common ancestor of humans and chimpanzees. Expand
Cytoarchitectonic and receptorarchitectonic organization in Broca's region and surrounding cortex
TLDR
The Broca's region of the human brain is compared with the homologue region in the brain of apes, baboon and macaque monkey and two cytoarchitectonic areas (BA44, BA45) were identified as correlates of Broca’s area in the inferior frontal opercular and triangular parts. Expand
Cognitive control of orofacial and vocal responses in the human frontal cortex
TLDR
It is demonstrated that area 44 and the MCC are respectively involved in the cognitive selection of orofacial, non-speech vocal and verbal responses, and the feedback-driven adaptation of these responses – roles that are likely preserved across primates. Expand
Corticostriatal Projections of Macaque Area 44
TLDR
The role of area 44 as an interface between motor and nonmotor functional domains, possibly facilitated by rostral and caudal area 44 subregions with distinct corticostriatal connectivity profiles, is supported. Expand
Corticostriatal Projections of Macaque Area 44
TLDR
The role of area 44 as an interface between motor and non-motor functional domains, possibly facilitated by rostral and caudal area 44 subregions with distinct corticostriatal connectivity profiles, is supported. Expand
Cognitive control of orofacial motor and vocal responses in the ventrolateral and dorsomedial human frontal cortex
TLDR
It is proposed that the basic function expressed by the VLF–DMF network is to exert cognitive control of orofacial and vocal acts and, in the language dominant hemisphere of the human brain, has been adapted to serve higher speech function. Expand
Distinct neural networks for the volitional control of vocal and manual actions in the monkey homologue of Broca's area
TLDR
It is suggested that the primate inferior frontal cortex controls the initiation of volitional utterances via a dedicated network of vocal selective neurons that might have been exploited during the evolution of Broca’s area. Expand

The functional diversity of the cortical areas related to orofacial motor behavior and the somatotopical organization in the premotor areas of the frontal cortex are discussed. Expand
Variability of Broca's area homologue in African great apes: implications for language evolution.
TLDR
It is concluded that gross morphologic patterns do not offer substantive landmarks for the measurement of Brodmann's area 44 in great apes, and whether or not Broca's area homologue of great apes exhibits humanlike asymmetry can only be resolved through further analyses of microstructural components.

Functionally defined smooth and saccadic eye movement subregions in the frontal eye field of Cebus monkeys.
TLDR
It is proposed that the smooth eye movement subregion in Cebus monkeys may be comparable with the one described in macaque monkeys, and the existence of two subregions of the FEF was further confirmed by single-unit recording results. Expand

Asymmetric Broca's area in great apes
TLDR
The findings suggest that the neuroanatomical substrates for left-hemisphere dominance in speech production were evident at least five million years ago and are not unique to hominid evolution. Expand

It is suggested that the development of the lateral verbal communication system in man derives from a more ancient communication system based on recognition of hand and face gestures. Expand
Frontal eye field as defined by intracortical microstimulation in squirrel monkeys, owl monkeys, and macaque monkeys: I. Subcortical connections
TLDR
Connections that account for the parallel influence of the superior colliculus and the frontal eye field on visuomotor function are revealed and suggest that there has been little evolutionary change in subcortical connections of the frontal eyes fields since the time that these lines of primates diverged.

This study traced the afferent and efferent connections of the inferior region of area 6 by injecting small amounts of wheat germ agglutinin conjugated to horseradish peroxidase and fluorescent tracers into restricted parts of inferior area 6 and in physiologically determined fields of area 4.

Broca's region revisited: Cytoarchitecture and intersubject variability
TLDR
These morphologic asymmetries of area 44 provide a putative correlate of the functional lateralization of speech production and show that macroscopic features are not reliable landmarks of cytoarchitectonic borders. Expand

TLDR
It is argued that the mid-ventrolateral prefrontal cortex is involved in the active retrieval of information from posterior cortical association areas and increases in activity in theMid-dorsolateral region of the frontal cortex occur when the performance of the tasks requires monitoring of information in memory.
