“…Our study compliments this line of research by showing that this pattern could be extended to more communicative hand actions, namely gestures. However importantly, in the current study, although we observed an alpha band power decrease for both frontal and lateral gestures, unlike those studies examining non-communicative hand actions (Angelini et al, 2018;Drew et al, 2015), the alpha power did not differ between frontal and lateral orientation in our study. This data pattern attests to the hypotheses that alpha and beta power are dissociable during action or gesture observation, in the sense that alpha power decrease might be more related to sensory/motor perception in general, whereas the beta band is more sensitive to finegrained motor-related features (Brinkman et al, 2014;He et al, 2018a;Salmelin et al, 1995).…”

“…This finding not only supports the role of the beta band oscillations for perception of hand actions in general (Angelini et al, 2018;Avanzini et al, 2012;Järveläinen et al, 2004), but also corroborates the sensitivity of the beta band power to the observation of different types of gestures (He et al, 2018a;Quandt et al, 2012). Previous studies that directly tested perceptual differences of body orientation or view point of non-communicative hand actions (e.g., reaching) also showed a modulated decrease of beta power (and alpha power) for more allocentric view point (Angelini et al, 2018;Drew et al, 2015). Our study compliments this line of research by showing that this pattern could be extended to more communicative hand actions, namely gestures.…”

“…With functional magnetic resonance imaging (fMRI), it is suggested that two regions in the left hemisphere, the left posterior superior temporal sulcus and the left inferior frontal gyrus are crucially involved in the semantic combination and semantic integration between gesture and verbal speech (Dick et al, 2012;Green et al, 2009;He et al, 2015;He et al, 2018b;Holle et al, 4 actions (reaching, grasping, and etc.) observed from egocentric vs. allocentric view-point elicited greater sensorimotor-related alpha or beta band power decrease (Angelini et al, 2018;Drew et al, 2015). This line of research indicates that body orientation (or view-point) has direct impact on hand action perception.…”

Body orientation of gesture entails social-communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face-to-face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an EEG experiment presenting to participants (n=21) videos of frontal and lateral hand gestures of five-seconds (e.g., raising a hand), followed by visually presented sentences that are either congruent or incongruent with the hand gesture (e.g., 'the mountain is high/low…'). All participants underwent a semantic-probe task, judging whether a target word is related or unrelated to the gesture-speech event. EEG results suggest that, during the perception phase of handgestures, while both frontal and lateral gestures elicited power decrease in both the alpha (8-12Hz) and the beta (16-24Hz) bands, lateral gestures elicited reduced power decrease in the beta band when compared with frontal gestures. For sentence comprehension, at the critical word whose meaning is congruent/incongruent with the gesture, frontal gestures elicited an N400 effect for gesture-sentence incongruency. More importantly, this incongruency effect was significantly reduced for lateral gestures. The findings suggest that body orientation plays a crucial role in gesture perception, and that its inferred socialcommunicative intention influences gesture-sentence semantic integration in an interactive manner.

“…Human data support the relevance of the functional link between the viewpoint and spatial location of observed actions. Indeed, when actions are displayed on a screen, they either evoke similar motor activation regardless of the viewpoint from which they are observed 13 or, most often, induce an increased motor resonance when seen from a subjective perspective 14 – 17 . Furthermore, human studies using a variety of techniques have provided converging evidence that motor resonance is stronger in ‘the here and now’, that is, during live presentation of actions compared to presentation of videos with the same motor content 18 – 20 , as previously demonstrated in monkeys 4 .…”

Spatial and viewpoint selectivity for others’ observed actions in monkey ventral premotor mirror neurons

The spatial location and viewpoint of observed actions are closely linked in natural social settings. For example, actions observed from a subjective viewpoint necessarily occur within the observer’s peripersonal space. Neurophysiological studies have shown that mirror neurons (MNs) of the monkey ventral premotor area F5 can code the spatial location of live observed actions. Furthermore, F5 MN discharge can also be modulated by the viewpoint from which filmed actions are seen. Nonetheless, whether and to what extent MNs can integrate viewpoint and spatial location of live observed actions remains unknown. We addressed this issue by comparing the activity of 148 F5 MNs while macaque monkeys observed an experimenter grasping in three different combinations of viewpoint and spatial location, namely, lateral view in the (1) extrapersonal and (2) peripersonal space and (3) subjective view in the peripersonal space. We found that the majority of MNs were space-selective (60.8%): those selective for the peripersonal space exhibited a preference for the subjective viewpoint both at the single-neuron and population level, whereas space-unselective neurons were view invariant. These findings reveal the existence of a previously neglected link between spatial and viewpoint selectivity in MN activity during live-action observation.

“…Theoretically, others’ actions perceived from egocentric perspectives, being more visually similar to self-actions, should induce a stronger activation in the motor system of the observer with respect to actions perceived from allocentric viewpoints. Nevertheless, experimental data so far available in monkeys 4 – 6 and humans 7 – 15 are inconsistent and definite evidence is still lacking. Indeed, a single-cell recording study in macaques revealed view-dependent responses in most of F5 mirror neurons (MNs), which were tuned to one or, more frequently, two viewpoints among three tested perspectives (FP, lateral and TP).…”

During action observation, several visual features of observed actions can modulate the level of sensorimotor reactivity in the onlooker. Among possibly relevant parameters, one of the less investigated in humans is the visual perspective from which actions are observed. In the present EEG study, we assessed the reactivity of alpha and beta mu rhythm subcomponents to four different visual perspectives, defined by the position of the observer relative to the moving agent (identifying first-person, third-person and lateral viewpoints) and by the anatomical compatibility of observed effectors with self- or other individual’s body (identifying ego- and allo-centric viewpoints, respectively). Overall, the strongest sensorimotor responsiveness emerged for first-person perspective. Furthermore, we found different patterns of perspective-dependent reactivity in rolandic alpha and beta ranges, with the former tuned to visuospatial details of observed actions and the latter tuned to action-related parameters (such as the direction of actions relative to the observer), suggesting a higher recruitment of beta motor rhythm in face-to-face interactions. The impact of these findings on the selection of most effective action stimuli for “Action Observation Treatment” neurorehabilitative protocols is discussed.
