Document Summary

Therefore, they probably have a biological basis the behaviors displayed by sighted and blind athletes were very similar. This finding suggests that pride responses are innate rather than learned by observing them in others because such similarities occur across cultures, the physical expression of pride appears to be biologically based. Hypothalamus influences eating integrates the various inhibitory and excitatory feeding messages and organizes behaviors involved in eating. Hypothalamus monitors various hormones and nutrients and operates to maintain a state of homeostasis leptin involved in fat regulation is released from fat cells as more fat is stored. Might affect the reward properties of food and make it less appetizing important for long-term body fat regulation than for short-term eating control. Animals lacking the gene necessary to produce leptin become extremely obese, and injecting leptin into these animals leads to a rapid loss of body fat.
