科学领域:
- 神经科学是一个神经科学.
- 行为科学 行为科学
- 计算神经科学是一种神经科学.
背景情况:
- 情绪调节对于适应性行为至关重要.
- 中间前额叶皮层 (mPFC) 通过投射到底侧杏仁体 (BLA) 和核 (NAc) 调节情绪反应.
- 在不同的情绪状态和行为中,mPFC投射到BLA和NAc的功能作用尚未完全理解.
研究的目的:
- 调查中部前额叶皮层 (mPFC) 投射到底侧杏仁体 (BLA) 和核 (NAc) 在情绪调节中的不同功能作用.
- 探索这些通路如何编码不同的情绪状态,包括焦虑和积极影响.
- 检查这些途径在社会行为中的参与以及慢性情绪状态的影响.
主要方法:

Physiology of Emotion
732
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Cognitive Theories: Schachter-Singer Theory of Emotion
373
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
