害羞是指人际情境下的不适或抑制的一种倾向。针对害羞现象,从遗传学与神经递质影响、外周生理变化和神经影像技术的发展三个方面进行研究发现,害羞与5-羟色胺转运基因多态性、β1-肾上腺素受体等基因多态性有关;害羞个体的下丘脑—垂体—肾上腺(HPA)轴神经内分泌调节功能异常;害羞个体的颞上回、海马旁回、脑岛、小脑后叶的灰质密度增高,并且额叶、颞叶皮质及杏仁核等脑区的功能及功能连接表现异常。研究结果表明,害羞具有稳定的生物学基础,并且可能是一种多系统联合改变的结果。
Shyness refers to a tendency of discomfort or inhibition in interpersonal situations. In view of the shy phenomenon, from the genetics and neurotransmitter effects, peripheral physiology and neuroimaging technology development in three areas found that shy and serotonin transporter gene polymorphisms, β1-adrenoceptor and other genetic polymorphisms Sexual; shy individuals hypothalamus - pituitary - adrenal (HPA) axial neuroendocrine regulation dysfunction; shy individuals of the superior temporal gyrus, parahippocampal gyrus, cerebral island, posterior cerebellar gray matter density increased, and the frontal lobe, temporal lobe Cortical and amygdala and other brain areas of the functional and functional connection abnormalities. The results show that shyness has a stable biological basis and may be the result of a multi-system joint change.
