Dietary protein contains amino acids used in the brain for synthesis of neurotransmitters. Although information on pre-and post-natal exposure to low-protein diets in rodents is available, little is known about the effects of such diets on adult humans. Therefore, the behavioral and neurochemical consequences of exposure to a brief (11 days), low-protein (4%) diet in animals exposed to normothermic and hyperthermic test conditions were examined. In separate groups of animals, ...
