Is there a role for serotonin (5-hydroxytryptamine) in feeding?
International Journal of Obesity
|January 1, 1977
Summary
Serotonin (5-hydroxytryptamine) systems significantly influence feeding behavior. Evidence suggests serotonin plays an inhibitory role in food intake, potentially mediating satiety, which has implications for obesity research.
Area of Science:
- Neuroscience
- Behavioral Science
- Pharmacology
Background:
- Serotonin (5-hydroxytryptamine) is a neurotransmitter implicated in various physiological processes.
- Altered serotonin activity has been anecdotally linked to changes in appetite and eating patterns.
Purpose of the Study:
- To review and synthesize evidence on the role of serotonin systems in regulating feeding behavior.
- To explore the potential inhibitory function of serotonin in food consumption and satiety.
Main Methods:
- Review of experimental studies manipulating serotonin availability or receptor activity.
- Analysis of behavioral data related to food consumption following serotonin system alterations.
Main Results:
- Increased serotonin availability or receptor activation generally reduces food intake.
- Decreased serotonin activity or receptor blockade leads to increased food consumption.
- Methodological challenges exist in precisely measuring serotonin's effects on feeding.
Conclusions:
- Serotonin systems appear to exert an inhibitory influence on feeding behavior.
- Serotonin may play a key role in the mediation of satiety.
- Findings suggest implications for understanding obesity and developing therapeutic strategies.
