PS261 Lecture Notes - Lecture 4: Negative Feedback, Homeostasis
Document Summary
Cr influences by us; respond to the cr in a similar way to how we respond to the us. Assumes the cs acts like a substitute for the us. Thus cs will elicit a cr similar to the ur. After body is put off balance it senses this and triggers compensatory response to counteract the imbalance. Subject makes compensatory adjustments in anticipation of imbalance. Subject learns about cues that challenge the body"s balanced state. Each administration of a drug can be considered a conditioning trial. Direct effects of drug us causes physiological changes that disrupt homeostasis, us then triggers a ur to counteract the imbalnce in the form of an elicited response that compensates for direct effects of us. Stimuli present when drug is taken css become associated with drug effects us and come to elicit a cr that causes conditioned compensatory responses in anticipation of the drug.
