Welcome to the Wikiversity learning project about the neurobiology of emotion. This is a learn by doing project where participants collaborate to explore what neuroscience research has revealed about the biology of emotion.
This project is starting with a literature review, so please add useful links to this page and participate in discussion of previously published research.
Reading
[edit | edit source]If you are not familiar with the major brain regions that have been associated with emotions then start with the introductory reading, below.
Introductory
[edit | edit source]Video: Charlie Rose: The Brain Series, particularly episode seven on the role that emotions play in decision making and social interaction, and episode eight, part two of the emotional brain, dealing with negative emotions such as fear and anxiety. (transcripts also available)
Textbook. Start with the 2001 Neuroscience textbook by Dale Purves, et al. and read the case study about patient "SM" then read other sections of the textbook chapter about emotion:
- Physiological Changes Associated with Emotion
- The Integration of Emotional Behavior
- The Limbic System
- The Importance of the Amygdala
- The Relationship between Neocortex and Amygdala
- Cortical Lateralization of Emotional Functions
- The Interplay of Emotion and Reason
- Summary
Published research by scientists such as António Damásio is cited and discussed in the Neuroscience textbook by Dale Purves, et al.
Research literature
[edit | edit source]If you are new to study of the neurobiology of emotion you might want to start by reading some review articles before looking at the detailed data reports.
Recent review articles
[edit | edit source]- Development. Developmental Neuroscience Perspectives on Emotion Regulation by H. Hill Goldsmith, Seth D. Pollak and Richard J. Davidson in Child development perspectives volume 1, pages 132–140 (2008). Goldsmith et al. review twin studies that have investigated genetic influences on the regulation of emotions. See the review by Banaschewski et al. for a more up-to-date review of the search for specific genes involved in emotional control. Also reviewed are forms of brain plasticity such as "extinction" as a type of emotion learning that is discussed in the The Brain Series. Another reviewed topic is the use of neuroimaging to explore the brain circuitry involved in the regulation of emotions.

Specific brain regions involved in emotion
[edit | edit source]In "What does the amygdala contribute to social cognition?", it is suggested that the amygdala plays a role in allowing humans to understand the emotions of others, particularly when we look at faces. Is the subject SM a representative experimental subject? --JWSchmidt 09:11, 18 August 2010 (UTC)
- Decety & Moriguchi cite additional patients with limbic system damage and altered emotions (cases N.M and N.K.). --JWSchmidt 17:52, 19 August 2010 (UTC)
- Jabbi et al. and Bird et al. describe roles for insular cortical areas in emotion (insular cortex connects to the amygdala). What are the distributed neural networks that make emotion possible? --JWSchmidt 00:52, 20 August 2010 (UTC)
Kuraoka & Nakamura recorded from individual neurons and showed that there are neurons in the monkey amygdala that respond to either facial or vocal emotional stimuli. Jabbi et al. studied humans using fMRI and observed that anterior insular cortex was active when test subjects either 1) saw others look disgusted or 2) tasted unpleasant liquids to induce disgust or 3) read and imagine scenarios involving disgust. Such experiments suggest that limbic system components including the amygdala and insular cortex contain neurons with activity patterns corresponding to the generation of core emotional responses that can be elicited by several different types of stimuli. --JWSchmidt 16:58, 20 August 2010 (UTC)
