An example of mirror neuron (Unit 76) activating during the observation of an affiliative facial gesture, typical of macaques, made by the experimenter (left) and during the observation of a similar gesture performed by the monkey (right) (from Ferrari et al., 2003). The histogram represents the average of 10 trials. Rasters and histograms are aligned with the moment in which the facial gesture was fully expressed.
