Functional Brain Systems: Limbic System01:15

Functional Brain Systems: Limbic System

3.0K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Role of Amygdala in Memory01:16

Role of Amygdala in Memory

284
The amygdala is a small, almond-shaped structure responsible for processing and storing memories, particularly those linked to emotions like fear and stress. It plays an essential role in the brain's response to emotionally significant events and often enhances memory formation by triggering stress hormone release. The amygdala is vital for encoding and retrieving memories associated with fear or stress, a process that is adaptive by helping organisms avoid dangerous situations.

Aggression01:47

Aggression

27.8K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Physiology of Emotion01:20

Physiology of Emotion

952
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...

Secondary Motives: Affiliation Motivation and Aggression Motivation

363
Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

1.3K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Area of Science:

  • Neurobiology
  • Developmental Psychology
  • Clinical Neuroscience

Background:

  • Reactive aggression is linked to impaired amygdala-prefrontal connectivity.
  • The amygdala plays a crucial role in modulating reactive aggression.
  • Understanding these neural networks is key to addressing aggressive behaviors.

Approach:

  • This review synthesizes current research on amygdala dysfunction and its connection to reactive aggression.
  • It examines the role of moral decision-making and emotion regulation in a developmental context.
  • The review explores brain network connectivity factors predisposing individuals to reactive aggression.

Key Points:

  • Impaired amygdala-prefrontal connectivity is a proposed neurobiological basis for reactive aggression.
  • Dysfunctional brain networks involving the amygdala are central to reactive aggressive behavior.
  • Developmental factors influencing moral decision-making and emotion regulation are critical.

Conclusions:
