背景情况:
- 社会决策网络 (SDN) 对社会行为至关重要,并且在整个物种中得到保护.
- 爬行动物SDN功能在很大程度上仍未被探索,尽管蛇拥有先进的社会感知.
- 蛇表现出有限的社会行为范围,使它们成为研究基本SDN函数的理想选择.
研究的目的:
- 研究爬行动物中SDN的功能,特别是球形 (Python regius).
- 为了确定蛇在社交互动期间激活的大脑区域.
- 为了比较蛇的SDN激活与其他种群中观察到的激活.
主要方法:
- 球形被安置在同一个同性同类物种中一个小时.
- 使用Fos免疫活性来评估神经激活.
- 在社会互动的蛇和对照者之间比较了Fos数量.
主要成果:
- 社交互动增加了SDN关键区域的Fos计数,包括中枢杏仁体,前视区域,核和底侧杏仁体.
- 在腹部杏仁体中观察到差异性Fos免疫活性,这表明它在大脑间区域通信中发挥了作用.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

01:20Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

02:39Predator-Prey Interactions
16.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
