Neural Correlates of Feeding and Memory
- Neuropsychology can explore the neural correlates of feeding through damage to various brain areas resulting in unusual eating behavior.
- Specific brain areas, such as the amygdala and orbitofrontal cortex, when damaged, can lead to abnormal eating patterns.
- Lesions in certain brain areas can aid in understanding the function of specific brain regions and raise important issues in biological models of eating.
- HM, a patient with dense anterograde amnesia, exhibited unusual eating behavior, consuming multiple meals shortly after each other without changes in hunger or fullness reports.
- HM's case suggests that the control of eating may be under greater cognitive control than previously believed, indicating the importance of cognition in regulating food intake.
- Research on the effects of hippocampal damage on eating has revealed that amnesiac patients readily eat second meals shortly after the first, without explicit awareness of having eaten just before.
- Memory plays a significant role in food intake, as recalling what has been eaten can reduce food intake, while distraction can increase food intake.
- The hippocampus may play a role in regulating food intake, and diets rich in saturated fat and added sugar can selectively damage the hippocampus.
- Neurochemical modulation of appetite, particularly neurotransmitters like Serotonin and Dopamine, has been a significant focus of research for drug development in treating obesity and anorexia.
- Raising levels of Serotonin and Dopamine can inhibit eating, and many drugs used in psychiatry that affect these neurotransmitters can lead to weight disturbances.
- Serotonin increases may induce satiation and satiety by reducing meal size, frequency, and eating rate, and has been targeted in weight-loss drugs.
- Neuropeptide Y (NY) in the hypothalamus increases eating, and the presence of nutrients in the gut can lead to its central suppression, reducing eating.
