视觉刺激引起的情绪唤起是日常生活中的一种常见现象.本文通过功能核磁共振成像了解与视觉情绪刺激相关的脑功能归属.15位女性在其一个月经周期内接受了3次或更多的功能核磁共振扫描,实验中视觉刺激的形式包括成人影片与图片,平均所有测试结果得到了平均脑兴奋图.在平均脑兴奋图中可以发现,图片和影片形式的刺激均能有效地引起额下回的兴奋,与其他的兴奋脑区不同,呈现明显的右侧优势.根据实验结果,本文首次提出了右脑额下回在视觉感情信息处理中起到一定的作用,并且提出大脑额下回功能的优势化是双向而不是单向(向左侧)集中的.
視覺刺激引起的情緒喚起是日常生活中的一種常見現象.本文通過功能覈磁共振成像瞭解與視覺情緒刺激相關的腦功能歸屬.15位女性在其一箇月經週期內接受瞭3次或更多的功能覈磁共振掃描,實驗中視覺刺激的形式包括成人影片與圖片,平均所有測試結果得到瞭平均腦興奮圖.在平均腦興奮圖中可以髮現,圖片和影片形式的刺激均能有效地引起額下迴的興奮,與其他的興奮腦區不同,呈現明顯的右側優勢.根據實驗結果,本文首次提齣瞭右腦額下迴在視覺感情信息處理中起到一定的作用,併且提齣大腦額下迴功能的優勢化是雙嚮而不是單嚮(嚮左側)集中的.

Visually-induced erotic arousal evoked by pornographic visual stimuli,such as films or photographs,is a common occurrence in human behavior.The brain activation associated with visual erotic stimuli in heterosexual right handed females is studied.Functional magnetic resonance imaging is used to investigate 15 female partici-panterotic arousal induced by visual stimuli in film and picture forms,respectively,performing three or more times during their menstrual cycle on a 3.0T magnetic resonance imaging scanner.There is activation of a set of bilateral brain areas,including the inferior lateral occipital cortex,the anterior supramarginal gyrus,the parietal operculum cortex,the superior parietal lobules,the right inferior frontal gyrus,the cerebellum,the hypothala-mus,the thalamus,the hippocampus,and the mid-brain.From different regions,the brain activation is observed and the inferior frontal gyrus has found to be task-independent.Furthermore,the right inferior frontal gyrus has more activation than the left inferior frontal gyrus.The result shows that the right inferior frontal gyrus plays an important role in pornographic information processing rather than being activated stimuli property specific.It is presented for the first time that the functional laterization of the inferior frontal gyrus is bi-directional rather than single (left) directional.
