The thalamus relays sensory information to the appropriate area of the cerebral cortex. The cerebellum coordinates bodily movement, controls posture, and maintains equilibrium. The limbic system consists of three structures that mediate motivated behaviors, emotional states, and certain kinds of memory. The hippocampus plays an important role in memory, especially in long-term storage of information. The hypothalamus is one of the smallest brain structures and regulates physiological processes, including eating, drinking, temperature regulation, and sexual arousal.
Homeostasis is the body's internal balance or equilibrium.
The Cerebrum 1. The cerebrum is the part of the brain that regulates higher levels of cognitive and emotional functioning. The cerebral cortex is composed of billions of cells from the outermost layer of the cerebrum. The two nearly symmetrical halves of the cerebrum are the cerebral hemispheres. The two hemispheres are connected by a thick mass of nerve fibers, collectively referred to as the corpus callosum.
