Document Summary
Drive: reversible internal condition that orients individuals towards specific types of goals. Regulatory drive: those such as hunger, thirst, thermoregulation, and sleep that help to maintain physiological homeostasis and are needed for immediate survival. Energizing direct and animal to act and direct behaviour toward a goal, and help animals sustain their behaviour until they achieve their goal. Reward-seeking state reinforced by the pleasure experienced once the reward is obtained. Electrical stimulation to certain parts of the brain (basal forebrain) in rats was more motivating than food, showing animals can be motivated by rewards that have no obvious value for survival and drive reduction (i. e. nonregulatory drive) Certain hubs or nuclei in the brain involve detection of imbalances (e. g. low energy/glucose and salt), decision making (executing a plan to seek food), and motor output (action of hunting) E. g. may not be aware body"s salt is low, but suddenly crave salty foods after an endurance event.
