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 hypothalamus, 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.展开更多

Based on surveys of the public in Canada,Mexico, and the United States, the article shows the levels of concern over climate change threats, perceived risk,knowledge of climate change policies, levels of uncertainty, and other perception factors to help understand the relationships between public perceptions and policy preferences for renewable energy. Results show national differences between the three countries in nearly all climate change perceptions, with Mexico reflecting the highest levels of concern and the United States the lowest. Mexico also shows the greatest support for renewable energy sources. However, the results show very high levels of uncertainty about climate change dimensions concerning risk, science, and knowledge and the effectiveness of policy approaches. The data demonstrate strong statistical correlations between risk perception factors and preferences for mitigation policies in the form of renewable energy policies.展开更多
