Brain Activation in Response to Disgustful Face Images with Different Backgrounds

摘要: Previous studies have demonstrated that the stimulus of a fearful and disgustful face images lead to activation neural responses in medial temporal lobe. In particular, it was reported seeing image activated insula area brain. these studies, no background were used with facial stimuli. However, normal daytoday always background. Moreover, are considered important art forms (painting, photography, movies, etc.) for eliciting effective expressions. We assessed effect on brain by using functional magnetic resonance imaging (fMRI). During fMRI scanning, presented repeatedly 8 healthy righthanded males. Facial stimuli comprised 5 photographs selected from Paul Ekman’s database (Ekman Friesen 1976). The 2 photographs-one is worms other flower garden. It thought coincide point impression. After subjects rated impression created Plutchik scale. Significant effects against minus garden ttest displayed as statistical parametric maps (SPMs) SPM2 software. results right insula, more than Therefore, together create overall difference possibly induced creation this This demonstrates importance forming an images.
