“…Functional magnetic resonance imaging studies have suggested that, when compared to observing others in non-painful conditions (neutral condition), observing other's in painful condition triggers stronger activation in a larger set of brain regions, including the anterior insula (AI), anterior cingulate cortex (ACC), amygdala, etc (Keysers, Kaas, & Gazzola, 2010;Keysers, Meffert, & Gazzola, 2014;Lamm, Decety, & Singer, 2011;Rizzolatti & Sinigaglia, 2010). ERP studies, on the other hand, demonstrated more positivity to painful than neutral stimuli in the in N1, N2, and P3 components (Han, Fan, & Mao, 2008;Ibáñez et al, 2011;Meng et al, 2012).…”
