“…More specifically, several EEG studies have shown mu rhythm suppression during the observation of different types of grasping (Muthukumaraswamy et al, 2004; Muthukumaraswamy and Johnson, 2004a; Perry and Bentin, 2009; Streltsova et al 2010), meaningless gestures (Babiloni et al, 2002; Streltsova et al 2010) and sequential finger movements (Calmels et al, 2006). It is interesting to note that such motor activation can also be induced by the observation of static images portraying actions (Johnson-Frey et al, 2003; Mado-Proverbio et al, 2009).…”

The role of the motor system in the perception of visual art remains to be better understood. Earlier studies on the visual perception of abstract art (from Gestalt theory, as in Arnheim, 1954 and 1988, to balance preference studies as in Locher and Stappers, 2002, and more recent work by Locher et al., 2007; Redies, 2007, and Taylor et al., 2011), neglected the question, while the field of neuroesthetics (Ramachandran and Hirstein, 1999; Zeki, 1999) mostly concentrated on figurative works. Much recent work has demonstrated the multimodality of vision, encompassing the activation of motor, somatosensory, and viscero-motor brain regions. The present study investigated whether the observation of high-resolution digitized static images of abstract paintings by Lucio Fontana is associated with specific cortical motor activation in the beholder's brain. Mu rhythm suppression was evoked by the observation of original art works but not by control stimuli (as in the case of graphically modified versions of these works). Most interestingly, previous visual exposure to the stimuli did not affect the mu rhythm suppression induced by their observation. The present results clearly show the involvement of the cortical motor system in the viewing of static abstract art works.

“…We therefore also investigated the decreasing 525 variability of neural activity prior to self-initiated action using spectral methods (see materials 526 and methods). Specifically, we focused on the event-related desynchronization (ERD) of 527 beta band activity (Bai et al, 2011;Calmels et al, 2006;Stancák and Pfurtscheller, 1996). 528…”

al., 2015). We thus compared EEG variability prior to self-initiated skip actions with variability 54 prior to externally-triggered actions occurring at a similar time. We used a systematic 55 modelling approach to show that a stochastic accumulator framework could indeed explain 56 the pattern of EEG variability, but only by assuming an additional process modulating the 57 level of neural noise. 58 Materials and Methods 592.1. Participants. 60 24 healthy volunteers, aged 18-35 years of age (9 male, mean age = 23 years), were 61 recruited from the Institute of Cognitive Neuroscience subject data pool. Two participants 62 were excluded before data analysis (they provided insufficient EEG data because of 63 excessive blinking). All participants were right handed, had normal or corrected to normal 64 vision, had no history or family history of seizure, epilepsy or any neurologic or psychiatric 65 disorder. Participants affirmed that they had not participated in any brain stimulation 66 experiment in the last 48 h, nor had consumed alcohol in the last 24 h. Participants were 67 paid an institution-approved amount for participating in the experiment. Experimental design 68 and procedure were approved by the UCL research ethics committee, and followed the 69 principles of the Declaration of Helsinki. 70 Behavioural task and procedure. 71Participants were placed in an electrically shielded chamber, 55 cm in front of a computer 72 screen (60 Hz refresh rate). After signing the consent form, the experimental procedure was 73 explained and the EEG cap was set up. The behavioural task was as follows: participants 74 were instructed to look at a fixation cross in the middle of the screen. The colour of the 75 fixation cross changed slowly and continuously throughout the trial. This colour always 76 started from 'black' and then gradually changed to other colours in a randomised order. The 77 fixation cross changed colour gradually (e.g., from green to pink), taking 2.57 s. The fixation 78 cross was initially black, but the sequence of colours thereafter was random. At the same EEG recording. 130While participants were performing the behavioural task in a shielded chamber, EEG signals 131 were recorded and amplified using an ActiveTwo Biosemi system (BioSemi, Amsterdam, 132

“…Mirror neurons were first discovered in the ventral premotor cortex (PMv) (area F5) of the macaque monkey and were shown to fire while the monkey executes a specific action, but also when the monkey merely observes the same action performed by others (Di Pellegrino et al, 1992;Fadiga et al, 1995Fadiga et al, , 2005Rizzolatti et al, 1996;Rizzolatti & Craighero, 2004). Using a variety of neuroimaging and neurophysiological techniques, a similar 'mirror mechanism' has been demonstrated in the human brain, which includes, in addition to PMv, also the dorsal premotor cortex (PMd), supplementary motor area (SMA), primary motor cortex (M1) and the inferior parietal cortex (IPC) (Fadiga et al, 1995;Hari et al, 1998;Hamzei et al, 2003;Calmels et al, 2006;Kilner et al, 2009;Molenberghs et al, 2012;Kilner & Lemon, 2013). In the past, studies using single-pulse transcranial magnetic stimulation (TMS) to measure changes in corticomotor excitability in M1 during movement observation have consistently demonstrated that observation-induced changes in excitability are highly specific to the actual muscles involved in the observed movement and occur time-locked to the observed kinematics while the movement unfolds (Fadiga et al, 1995;Gangitano et al, 2001;Alaerts et al, 2009aAlaerts et al, , 2009bAlaerts et al, , 2012Koch et al, 2010).…”

Recent theories propose that movement observation is not a "passive mirror" of ongoing actions but might induce anticipatory activity when predictable movements are observed, e.g., because the action goal is known. Here we investigate this mechanism in a series of 3 experiments, by applying transcranial magnetic stimulation (TMS) to primary motor cortex (M1) while subjects observed either whole hand or precision grasping performed by an actor. We show that corticomotor excitability changes in a grip-specific manner but only once the grip can be decoded based on the observed kinematic cues (Exp. 1). By contrast, presenting informative contextual precues evokes anticipatory modulations in M1 already during the reach phase, i.e., well before the grip type could be observed, a finding in line with a predictive coding account (Exp. 2). Finally, we used paired-pulse (PP) TMS to show that ventral premotor cortex (PMv) facilitates grip-specific representations in M1 but only while grip formation is observed. These findings suggest that PMv and M1 interact temporarily and mainly when motor aspects of hand-object interactions are extracted from visual information. By contrast, no sustained input from PMv to M1 seems to be required to maintain action representations that are anticipated based on contextual information or once the grip is formed (Exp. 3).
