“…Electrophysiological recording studies have demonstrated that neurons in the intraparietal and rostral inferior parietal cortex of the monkey (the same region where we placed a ROI) are specialized for somatosensory and spatial responses that involve the hand, arm and mouth area (Hyvärinen and Shelepin, 1979;Leinonen and Nyman, 1979). The diffusion-weighted data, in agreement with the monkey literature, has identified the SLF III pathway linking area 44 with the inferior parietal lobule in the majority of the subjects (Figs.…”

“…In the macaque monkey, the rostral part of the inferior parietal lobule that encompasses areas PF and PFG projects to the ventral premotor region in- cluding the depth of the ventral branch of the arcuate sulcus (Petrides and Pandya, 1984) where the homolog of area 44 lies (Petrides et al, 2005). The rostral part of the inferior parietal lobule is involved in complex somatosensory responses of the face and arm (Hyvärinen and Shelepin, 1979;Leinonen and Nyman, 1979). The other ROI was placed within the mid-portion of the superior temporal gyrus and sulcus (i.e., area 22), anterior to Heschl's gyrus (Fig.…”

The anatomical connectivity of ventrolateral frontal areas 44 and 45, which in the human brain constitute Broca's region, has been revisited on the basis of experimental anatomical tracer evidence in the nonhuman primate that the homologues of areas 44 and 45 have distinct bidirectional corticocortical connections. Here we show, using high angular resolution diffusion imaging in the living human brain, a dissociation between the specific projections from the pars opercularis (area 44) and the pars triangularis (area 45) in the ventrolateral frontal lobe. As in the macaque monkey, area 44 has distinct connections with the rostral inferior parietal lobule via the third branch of the superior longitudinal fasciculus. In contrast, area 45 connects with the superior temporal gyrus, anterior to Heschl's gyrus, via the extreme capsule fiber system. These results highlight the differences in connectivity between areas 44 and 45 which had previously been thought to be uniformly connected with the posterior temporal region via the arcuate fasciculus. We also provide evidence in the human brain that the arcuate fasciculus, as in the macaque monkey brain, connects the posterior superior temporal region with dorsolateral frontal areas 8 and rostral 6 that lie above areas 44 and 45. Thus, monkey and human evidence suggests that the connections of areas 44 and 45 are much more differentiated than had previously been thought and provide the basis for studies searching for their differential contribution in function.

“…There is evidence, although limited, that mirror neurons might be present in area 7b in monkeys (Ref. 32). Finally, as discussed earlier, it is likely that F5 is the monkey homolog of Broca's area.…”

In monkeys, the rostral part of ventral premotor cortex (area F5) contains neurons that discharge, both when the monkey grasps or manipulates objects and when it observes the experimenter making similar actions.These neurons (mirror neurons) appear to represent a system that matches observed events to similar, internally generated actions, and in this way forms a link between the observer and the actor. Transcranial magnetic stimulation and positron emission tomography (PET) experiments suggest that a mirror system for gesture recognition also exists in humans and includes Broca's area. We propose here that such an observation/execution matching system provides a necessary bridge from 'doing' to 'communicating',as the link between actor and observer becomes a link between the sender and the receiver of each message.

“…However, in order to code the images of the movement of the hand in space, information about joint displacements and visual motion in the environmental space should be integrated. Up to the present, only a few bimodal neurons in the intraparietal cortices were reported to convey joint information (Duhamel et al, , 1998Leinonen, 1980;Leinonen, Hyvärinen, Nyman, & Linnankoski, 1979;Leinonen & Nyman, 1979). Hence, the first objective of this study was to systematically describe the receptive field properties of intraparietal bimodal neurones that respond both to forearm joint displacements and to visual stimuli moving in particular directions.…”

“…Hence, in order to implement body motions in space, their "static" spatial information including location (at the beginning and end of the motion), configuration (of the body and its trajectory along the executed motion), and their combination could properly manifest the kinematics of the motion in space, rather than the agglomerated perception of fragmental pieces of "movements" themselves. Indeed, most previous studies have emphasized this "static" information (Colby et al, 1993;Fogassi et al, 1996;Graziano & Gross 1993;Graziano, Yap, & Gross, 1994;Leinonen et al, 1979;Leinonen & Nyman, 1979;Rizzolatti, Scandolara, Massimo, & Gentilucci, 1981). Representative visual responses are of the approach-type, whose receptive field can code the location of body parts in space, anchoring to tactile receptive fields of the corresponding body parts regardless of posture.…”

We can mentally calibrate the directions of our bodily movements into visual coordinate systems to achieve purposeful actions in space. Alternatively, we can apprehend characteristics of the peri-personal space through actions performed by our own body parts. Such interactions between representations of our body motions and extrinsic space should occur in the intraparietal cortices, where the hierarchically processed somatosensory information adjoins the information on spatial vision processed along the dorsal stream. In this brain area of monkeys, we analyzed the response properties of "bimodal joint neurones", which responded simultaneously to forearm joint displacements and visual stimuli moving in one direction in space. For the majority of these neurones, the directions of hand movements in space as a result of adequate joint displacements were congruent with the preferred directions of the moving visual stimuli. When the arm position was rotated, the preferred direction of the joint displacement became inverted so as to match the induced hand movement in space with the preferred visual stimulus direction. On the other hand, in some neurones the visual preferred direction became inverted when the joint was rotated, becoming to match the preferred direction of joint displacement. Hence, intraparietal neurones appear not only to represent mental recalibration of intrinsic movements into extrinsic coordinates, but also render delineation of extrinsic space through intrinsic actions.
