性活动是人类最重要的活动之一,大脑在性活动的唤醒过程中又起着关键作用。近年来认知神经科学的研究发现,在性唤起心理过程中,对应于认知、动机、情绪表现和自主神经活动四个方面,人的大脑有相应的活动方式,主要表现在:①认知过程主要是对性刺激的注意和编码评估,此过程激活的脑区有枕叶视觉区、顶叶皮质和前额叶;②动机过程是对性刺激诱发的性冲动的监控与调节,主要涉及的脑区为前扣带回、前额叶背外侧皮层;③情绪表现为伴随性唤起时的极度兴奋,此时,杏仁核、丘脑、小脑呈显著激活状态;④自主反应表现为性唤起时内分泌系统激活及对性器官的调节反应,脑岛和下丘脑对此调控扮演了重要角色。
Sexual activity is one of the most important human activities, the brain plays a key role in the wake-up process of sexual activity. In recent years, cognitive neuroscience research found that in the process of sexual arousal, corresponding to cognitive, motivation, emotional performance and autonomic activity in four aspects, the human brain has a corresponding activity, mainly in the: ① cognitive The process is mainly the attention and coding assessment of sexual stimulation, the process of activation of the brain area occipital visual area, the parietal cortex and the prefrontal cortex; ② motivation process is the sexual stimulation induced sexual impulse monitoring and regulation, mainly related to The anterior cingulate gyrus and the dorsolateral prefrontal cortex in the brain area showed an extreme excitement accompanied by sexual arousal. At this time, the amygdala, thalamus and cerebellum were significantly activated. The autonomic reaction manifested as sexual arousal endocrine system Activation and regulation of sexual organs, the insula and hypothalamus play an important role in this regulation.
