Physiology of Emotion01:20

Physiology of Emotion

1.2K
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...

Labeling Emotion01:20

Labeling Emotion

226
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Physiological Theories: James-Lange Theory of Emotion

842
The James-Lange theory of emotion, proposed by William James and Carl Lange in the late 19th century, asserts that emotions are the result of physiological reactions to external stimuli. Contrary to the traditional view, which suggests that emotions directly arise from the perception of stimuli, this theory proposes that emotions occur as a consequence of the body's responses to such stimuli. According to this framework, an emotional experience is a cognitive interpretation of physiological...

Cognitive Theories: Schachter-Singer Theory of Emotion

560
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.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...

Physiological Theories: Cannon-Bard Theory of Emotion

740
The Cannon-Bard theory of emotion, proposed by Walter Cannon and Philip Bard, challenges the notion that emotions are solely the result of physiological responses. Instead, this theory suggests that emotional experiences and physiological arousal occur simultaneously but operate through independent mechanisms. This dual response is initiated by the brain, specifically by the thalamus, which plays a critical role in processing sensory information.
Upon perceiving a stimulus, such as a dangerous...

Cognitive Theories: Lazarus Mediational Theory of Emotion01:17

Cognitive Theories: Lazarus Mediational Theory of Emotion

1.1K
Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.
Cognitive Appraisal and Emotional Response
Lazarus proposed that...

Area of Science:

  • Neuroscience
  • Microbiology
  • Bioinformatics

Background:

  • Gut microbiota influence brain regions linked to emotion and mood.
  • Existing literature reviews are systematic but labor-intensive.
  • Knowledge graphs offer a novel approach to explore complex biological relationships.

Purpose of the Study:

  • To explore the relationship between probiotics and emotion using a knowledge graph.
  • To develop an end-to-end method integrating text mining, concept reasoning, and evidence classification.
  • To create an evidence-based emotion-probiotic knowledge graph.

Main Methods:

  • Built a probiotics knowledge graph using text mining on PubMed articles.
  • Retrieved and reasoned about probiotic-emotion relationships.
  • Annotated relationships and incorporated evidence levels for visualization.

Main Results:

  • Constructed a probiotics knowledge graph with over 40 million triples.
  • Annotated 1453 PubMed articles, identifying 4131 evidenced emotion-probiotic associations.
  • Visualized emotion-probiotic relationships with incorporated evidence levels.

Conclusions:

  • Demonstrated an effective reasoning-based pipeline for relationship exploration.
