Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
Most homeostatic regulatory mechanisms involve negative feedback. Consider the control of body temperature, a process called thermoregulation. In thermoregulation, the relationship between heat loss, which occurs primarily at the body surface, and heat production, which occurs in all active tissues, is altered. The control center for thermoregulation is in the hypothalamus, a region of the brain (Figure 1-4a).
