本文综述了佛罗里达大学情绪与注意力研究中心(CSEA)的心理生理学和神经科学对情绪加工的研究,重点介绍了调节情绪表达的反射反应、神经结构和功能回路。研究者们共享的理论观点是,表达的情绪是建立在大脑中的动机回路上的,这些回路在进化史的早期发展起来,以确保个体及其后代的生存。这些回路对食欲和厌恶的环境和记忆线索做出反应,调节食欲和防御反射,调节感觉系统,动员有机体采取行动,并产生消极和积极的影响。这里回顾的研究评估了情绪的反射生理学,包括自主神经和躯体,研究在图片感知,记忆图像和有形的奖励和惩罚的背景下诱发的影响,并使用脑电图(EEG)和功能性磁共振成像(fMRI),探索大脑的动机电路,决定人类的情绪。
Psychophysiological and neuroscience studies of emotional processing undertaken by investigators at the University of Florida Laboratory of the Center for the Study of Emotion and Attention (CSEA) are reviewed, with a focus on reflex reactions, neural structures and functional circuits that mediate emotional expression. The theoretical view shared among the investigators is that expressed emotions are founded on motivational circuits in the brain that developed early in evolutionary history to ensure the survival of individuals and their progeny. These circuits react to appetitive and aversive environmental and memorial cues, mediating appetitive and defensive reflexes that tune sensory systems and mobilize the organism for action and underly negative and positive affects. The research reviewed here assesses the reflex physiology of emotion, both autonomic and somatic, studying affects evoked in picture perception, memory imagery, and in the context of tangible reward and punishment, and using the electroencephalograph (EEG) and functional magnetic resonance imaging (fMRI), explores the brain’s motivational circuits that determine human emotion.
