“…In fact, this rhythm does not seem to reflect a unitary phenomenon (Pfurtscheller et al., 65 1996;Pineda, 2005;Stancak and Pfurtscheller, 1995), but rather a combination of different 66 processes, potentially involved in the transformation of ''seeing'' into ''doing''. Moreover, a 67 complete overview of the spectro--temporal dynamics within the AON is missing, since many 68 studies in the literature considered only the alpha component (Kilner et al, 2006; Marshall et al., 69 2009;Pineda et al, 2000;Streltsova et al, 2010), or limited their 70 attention to the amplitude modulation of the oscillatory activity (Cochin et al, 1999; Hari et al., 71 1998; Kilner et al., 2009;Koelewijn et al, 2008; Orgs et 72 al., 2008), whereas studies on the temporal dynamics of brain activity during OBS and EXE focused 73 on the sensorimotor cortex only (Babiloni et al, 2002;Caetano et al, 2007). 74…”

14Several neuroimaging studies reported that a common set of regions are recruited during 15 action observation and execution and it has been proposed that the modulation of the µ rhythm, 16 in terms of oscillations in the alpha and beta bands might represent the electrophysiological 17 correlate of the underlying brain mechanisms. However, the specific functional role of these bands 18 within the µ rhythm is still unclear. Here, we used magnetoencephalography (MEG) to analyze the 19 spectral and temporal properties of the alpha and beta bands in healthy subjects during an action 20 observation and execution task. 21We associated the modulation of the alpha and beta power to a broad action observation 22 network comprising several parieto--frontal areas previously detected in fMRI studies. Of note, we 23 observed a dissociation between alpha and beta bands with a slow--down of beta oscillations 24 ACCEPTED FOR PUBLICATION -NEUROIMAGE2 compared to alpha during action observation. We hypothesize that this segregation is linked to a 25 different sequence of information processing and we interpret these modulations in terms of 26 internal models (forward and inverse). In fact, these processes showed opposite temporal 27 sequences of occurrence: anterior--posterior during action (both in alpha and beta bands) and 28 roughly posterior--anterior during observation (in the alpha band). The observed differentiation 29 between alpha and beta suggests that these two bands might pursue different functions in the 30 action observation and execution processes. 32Keywords: action observation and execution, alpha and beta rhythms, Event--Related 33Desynchronization (ERD), magnetoencephalography (MEG), internal models 34 35 36 INTRODUCTION 37Several studies report that our sensorimotor system is activated when we observe an 38 action performed by other people. This putative mirror--like activity in humans was found in the 39 precentral gyrus (vPM), the inferior frontal gyrus (IFG), the inferior parietal lobule (IPL), and 40 regions within the intraparietal sulcus (for a review see Rizzolatti and Sinigaglia, 2010). In addition 41 to this limited number of regions, neuroimaging studies observed a broader action observation 42 network (AON) which seems to be involved during action observation (OBS) and execution (EXE) 43 (Avenanti et al., 2012;Buccino et al., 2004;Gazzola and Keysers, 2009). A proposed theoretical 44 framework postulates that such AON implements forward and inverse internal models (Wolpert 45 and Ghahramani, 2000), which should be engaged during EXE and OBS. The internal models can 46 account both for how we link our actions to sensory consequences and how others' actions match 47 our own actions and sensations (Gazzola and Keysers, 2009;Iacoboni, 2005). It has been proposed 48 that the fronto--parietal AON has a predictive nature and according to this hypothesis, during 49 action observation the inverse and forward models are integrated to achieve a prediction of 50 ACCEPTED FOR PUBLICATION -NEUROIMA...

The observation of actions executed by others results in desynchronization of electroencephalogram (EEG) in the alpha and beta frequency bands recorded from the central regions in humans. On the other hand, mirror neurons, which are thought to be responsible for this effect, have been studied only in macaque monkeys, using single-cell recordings. Here, as a first step in a research programme aimed at understanding the parallels between human and monkey mirror neuron systems (MNS), we recorded EEG from the scalp of two monkeys during action observation. The monkeys were trained to fixate on the face of a human agent and subsequently to fixate on a target upon which the agent performed a grasping action. We found that action observation produced desynchronization in the 19-25 Hz band that was strongest over anterior and central electrodes. These results are in line with human data showing that specific frequency bands within the power spectrum of the ongoing EEG may be modulated by observation of actions and therefore might be a specific marker of MNS activity.

“…Research on the effects of action observation in MI has been dominated by human studies, in which gross changes in cortical activity during action observation have been assessed by functional magnetic resonance imaging (Cheng et al, 2007), changes in magnetoencephalogram and EEG power (Hari et al, 1998;Babiloni et al, 2002;Jarvelainen et al, 2004;Muthukumaraswamy and Johnson, 2004;Holmes et al, 2006), or by measuring the evoked responses to transcranial magnetic stimulation or medial nerve stimulation (Fadiga et al, 1995;Maeda et al, 2002;Borroni et al, 2005;Stefan et al, 2005). At the single-cell level, observation-related MI activity has only been used to set the initial parameters for motor decoding schemes (Hochberg et al, 2006;Wahnoun et al, 2006), but the origin, extent, and character of this activity has not been described previously.…”

A variety of studies have shown that motor cortical areas can be activated by observation of familiar actions. Here, we describe singleneuron responses in monkey primary motor (MI) and dorsal premotor (PMd) cortices during passive observation and execution of a familiar task. We show that the spiking modulation, preferred directions, and encoded information of cells in MI and PMd remain consistent during both observation and movement. Furthermore, we find that the presence of a visual target is necessary to elicit this congruent neural activity during observation. These findings along with results from our analysis of the oscillatory power in the beta frequency of the local field potential are consistent with previous imaging and EEG studies that have suggested that congruence between observation and action is a general feature of the motor system, even outside of canonical "mirror" areas. Such congruent activity has proposed relevance to motor learning, mimicry, and communication and has practical applications for the development of motorcortical neuroprostheses in paralyzed patients.
