摘要
丘脑枕核参与多条加工情绪信息的神经通路因而在情绪信息加工中具有重要作用。第一:丘脑枕核参与到上丘?丘脑枕核?杏仁核通路。该通路可以在没有初级视觉皮层参与情况下对情绪信息进行快速加工;第二:丘脑枕核以皮层?丘脑枕核?皮层环路和上丘?丘脑枕核?皮层通路两种形式参与到丘脑枕核?皮层通路。该通路通过控制皮层间同步化水平促进信息传递的效率;同时通过整合皮层和皮层下情绪信号扩大其在行为输出方面的影响力。
The pulvinar complex plays an important role in emotion processing by involving in multiple pathways. First, pulvinar involves in superior colliculus-pulvinar-amygdala pathway, which can process the emotional stimuli rapidly without the involvement of visual cortex. Second, pulvinar involves in pulvinar- cortical pathway in two different forms--cortico-pulvino-cortico circuits and coUiculo-pulvinar-cortical pathway. This neural mechanism can increase the efficacy of information exchange by controlling the degree of synchrony between cortical regions, and can amplify signals in a manner that enhances their behavioral impact by coordinating the signals between cortical and subcortical regions.
