Estímulos emocionais: processamento sensorial e respostas motoras

Abstract: Emotion can be functionally considered as action dispositions preparing the organism for either avoidance- or approach- related behaviors. In order to prepare an appropriate behavioral output, the organism has to be efficient in the encoding of relevant stimuli. We herein present evidence from neuroimaging studies that seeing emotional and arousing pictures leads to greater activation in visual cortex than seeing neutral ones. In addition to this facilitation of sensory processing, emotional stimuli prompt som… Show more

“…The ability of promptly answering to a stimulus is fundamental for an athlete's success in sports with characteristics such as the ones from volleyball. In order to prepare an appropriate motor output, the organism must be efficient in codifying relevant stimuli 7 . However, to react, the athlete must detect the opponent's action for, then, try to neutralize it.…”

“…Trabalhos realizados por nosso grupo sugerem que certos estímulos emocionais têm seu processamento cerebral privilegiado e capturam preferencialmente a atenção (Azevedo et al, 2005;Erthal, Oliveira, Machado-Pinhero, Pessoa & Volchan, 2004;Erthal et al, 2005;Mourao-Miranda et al, 2003;Pereira et al, 2004;Volchan et al, 2003). De fato, um trabalho publicado em 2005 mostrou que fotos emocionais distrativas interferiam na realização de uma tarefa mesmo em situações nas quais os recursos cerebrais para tais fotos eram reduzidos.…”

“…De acordo com o desenho de cada estudo, são utilizados testes padronizados ou tarefas (paradigmas) desenvolvidas para testar uma hipótese específi ca, ou ainda, observar de que modo o cérebro responde a esta tarefa, caso da RMf. Nos últimos anos, estudos brasileiros têm utilizado a RMf na estimação acurada da lateralização da memória e da linguagem (Branco & da Costa, 2006;Meneses et al, 2004), no estudo da modulação do comportamento através de estímulos emocionais (Volchan et al, 2003), verificar o correlato de ativação cerebral durante experiências emocionais (Moll et al, 2002), entre outras fi nalidades.…”
