Document Summary
In a normal nervous system, we have constant feedback with all our peripheral nervous system points (e. g. our skin is constantly contact with our brain). Hypothalamus comprised of nuclei they are involved in host activities such as hunger, sexual appetite, thirst lesions to these different structures which can cause deficit in terms of one seeking certain behaviours. Participates in nearly all aspects of motivated behaviour. Epithalamus another term for the pineal gland it"s associated more or less with biorhythms and circadian reactions. Thalamus relay center comprised of so many different circuitry nodes that allow for information to get from peripheral nervous system up to the cortex in both motor and sensory directions. Basal ganglia and limbic system are considered subcortical structures. Functions in sequencing movements so when it comes to disorders that involves the basal ganglia, it"s not the initiation of the movement that"s important but the coordination of movements that"s a progress.
