reticular activating system

Answer 13

part of the reticular formation; is responsible for regulating the sleep-wake cycle

Question 14

reticular formation

Answer 14

a network of nerves that carry messages between parts of the brain stem, helps regulate the intensity of pain and controls some parts of the body; also helps people focus on useful sensory imput while filtering out unnecessary stimuli

Question 15

somatosensory cortex

Answer 15

a specific area of the parietal lobe where signals are received

Question 16
