Document Summary
What is neuroscience and how do we study it: nervous system is made up of the cns and the pns o. The pns includes the somatic nervous system and autonomic nervous system. Autonomic: regulates smooth muscle, cardiac muscle, and glands. Parasympathetic: supports systems that replenish the body"s energy sources o. Continually produced, circulated, and reabsorbed through the brain and the ventricles o. When our body responds to arousing events in the environment, it is the autonomic nervous system that responds. Body curtails some of its regular maintenance functions to mobilize an immediate response. The faster the conductance of the current, the more moisture is present that indicates greater arousal. Study the structure of a living human brain through noninvasive procedures. Electrodes placed on the scalp to monitor electrical activity of the brain. Evoked potential: when electrical activity of the brain or other part of the nervous system is measured in response to a specific stimulus.
