Action recognition is fundamental to comprehend other`s attitudes and for social behavior. The processing of observed actions seems a product of sensorial and motor modules by transposing the observed movement to the observer own motor repertoire. Previous findings show premotor (PMC) and primary motor (M1) cortices activity during observation of human movements. It is suggested that motor activation has an important role in the perception and recognition of the observed movements and that this process is mediated by the Mirror-Neuron System. The observer motor network activation is independent of pictorial information, thus some studies where done using point light movement simulation the human form as stimuli. However, the specific role of the motor cortical network in action perception remains unclear. Therefore, we aim to evaluate cortical excitability changes due to human biological movement perception and also the possible physiological (i.e., cortical excitability in M1) and behavioral (i.e., perception of biological movement) interferences of transcranial direct current stimulation (tDCS) over M1 and PMC. Thereby it will be possible to evaluate the role of motor cortical network in movement perception and also, if there is a possibility to interfere in these abilities using non-invasive brain stimulation. Therefore, we propose three experiments, the first to evaluate biological movement observation effect in motor cortical excitability; the second to evaluate the combination of biological movement observation with tDCS over M1 or PMC effects in motor cortical excitability; and the third to evaluate if there is modulation of biological movement identification during tDCS over M1 or PMC.
