Topics
Andrew Huberman: 本集探讨了攻击性的神经机制、激素作用以及调控方法。攻击性分为反应性攻击、主动性攻击和间接攻击,它们有不同的生物学基础。大脑和身体中的神经回路介导不同类型的攻击性,涉及多种激素和神经递质。本集还介绍了心理和生理工具,以更好地控制攻击性,包括调节光照、雌激素敏感性、社会竞争和压力水平,以及补充ω-3脂肪酸、使用桑拿和热水浴、服用Ashwagandha等。此外,还讨论了咖啡因和酒精对冲动行为的影响,以及营养和补充剂在调节情绪和攻击性方面的作用。 Andrew Huberman: 研究表明,下丘脑腹内侧核(VMH)在攻击行为中起关键作用。VMH中表达雌激素受体的特定神经元负责产生攻击行为。睾酮本身不会增加攻击性,而是通过转化为雌激素来间接影响攻击性。日照时间长短会调节雌激素对攻击性的影响:日照时间长时,雌激素不会引发攻击性;日照时间短时,雌激素会增加攻击性倾向,这与皮质醇和血清素水平有关。皮质醇水平高和血清素水平低会增加雌激素引发攻击性的可能性。 Andrew Huberman: 一些工具可以用来调节攻击性,例如补充ω-3脂肪酸来调节情绪,通过阳光照射和桑拿浴来降低皮质醇水平,服用Ashwagandha来降低皮质醇,以及注意季节变化和光照情况。此外,咖啡因和酒精会增加冲动性,而补充左旋肉碱可以改善ADHD儿童的攻击行为。总而言之,控制攻击性需要综合考虑多种因素,包括神经机制、激素水平、环境因素和生活方式。

Deep Dive

Chapters
This chapter introduces the concept of aggression, differentiating between reactive, proactive, and indirect aggression. It highlights the involvement of neural circuits in mediating these behaviors and emphasizes the importance of context in understanding aggression.
  • Different types of aggression exist (reactive, proactive, indirect), each with unique biological mechanisms.
  • Neural circuits, not individual brain areas, mediate aggression.
  • Understanding aggression's biology helps understand other emotional states.

Shownotes Transcript

This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones—estrogen and testosterone—in mediating violent and and/or competive aggression. I also describe tools that can be used to modulate the factors that have been shown to ‘prime’ an individual for aggression, including sunlight, estrogen sensitivity, competition within social settings, and overall stress levels, and the hormone cortisol. I discuss how substances such as caffeine and alcohol can impact impulsive behaviors, and how nutrition and supplementation can be used to regulate mood and aggression.
