“…More recently, regarding the popularization of fMRI studies in neuroscience, IAPS has been included in a variety of neuroimage research protocols. A good example are the studies conducted by Moll and colleagues 10,11 , in which normal subjects were scanned while viewing IAPS pictures that they were asked to rate for emotional valence, arousal and moral content. These affective and moral ratings permitted the investigators to identify neural correlates of moral sensitivity and valence perception.…”

“…In the control group, VC increased by only 10%, and this might be associated with the learning effect of the technique. (9) One group of authors, (12) through the mapping of the brain regions involved in the processing of positive and negative stimuli, demonstrated that emotionally charged stimuli have a strong modulatory effect on the cortex and on the subcortical structures. However, there is still controversy regarding the effects of the strategy of positive reinforcement.…”

“…Métodos que utilizam imagens funcionais do cérebro, evocação de potencial em microeletrodos e estimulação magnética transcraniana são exemplos de técnicas de investigação utilizadas atualmente na pesquisa sobre empatia e que têm produzido importantes insights sobre os diferentes sistemas corticais envolvidos nas experiências empáticas (Damasio, 1996(Damasio, /2007Decety & Jackson, 2004;Moll et al, 2001). Dados importantes têm sido produzidos também a partir do estudo com pacientes autistas, sociopatas e esquizofrênicos (Preston & De Waal, 2002), indicando haver relação entre prejuízos em habilidades sociocognitivas e o comprometimento de determinados circuitos neuronais.…”

“…Ainda no que se refere aos substratos neurológicos da empatia, outros estudos indicam que a observação de expressões faciais ativa, em um nível subliminar, as mesmas expressões faciais no observador (Preston & De Waal, 2002), mesmo que ele não tenha consciência disso. Ademais, expressar intencionalmente uma emoção aumenta intensamente a atividade no sulco temporal superior, ínsula, amígdala e córtex motor, áreas que estão altamente envolvidas nas experiências emocionais (Moll et al, 2001). Nesse sentido, a ressonância afetiva que ocorre durante os episódios empáticos pode estar relacionada à capacidade humana de reconhecer e imitar expressões faciais e gestuais e aos mecanismos neurológicos subjacentes a essas funções.…”
