Document Summary
We can develop better medicinal interventions for motivational disorders. Gives us a list of important brain regions that might be important to motivation or reward but doesn"t tell us anything about the discrete functions of these structures. We can couple icss with additional experimental paradigms to get a better view of the neural mechanisms of motivated behavior. We want to return to a balance - we are motivated to correct de cits or restore surpluses. E. g. setpoint for energy needs => hunger arises when energy drops below setpoint => feeding behavior is initiated. Troughs in the graph represent location of setpoint. More accurately represented as a range, rather than a speci c, precise number. Sensory detector (e. g. thermometer) monitors current state of body. Can sense stop signals and stop corrective processes. Error detector - compares information from sensory detector to set point. Start signal - elicited to initiate a correction response.
