part of the brain that controls maintenance functions such as eating; helps govern endocrine system; linked to emotion and reawrd

master endocrine gland

part of the brain that helps control arousal

part of the brain that helps coordinate movement

part of the breain that controls breathing and heartbeat

pathway for neural fibers traveling to and from brain; controls simple reflexes

coordinates voluntary movement and balance and supports memories of such

part of the brain linked to emotion

part of the brain linked to memory

cells that protect neurons

where is the sensory cortex located

where is the motor cortex located

where is the auditory cortex

where is the visual cortex

examples of depressants

drugs that reduce neural activity and slow body functions

drugs that speed up body functions

what kind of processing is perception

what kind of processing is sensation

analysis that begins w the sensory receptors and works up to the brain's integration of sensory information

information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expecations

what are the perceptual constancies

the minimum stimulation needed to detect a particular stimulus 50% of the time

color, brightness, and shape are parts of which processing

the minimum difference between two stimuli required for detection 50% of the time

(noticeable difference)

diminished sensitivity as a consequence of constant stimulation

retinal receptors that detect black, white, and gray;

necessary for peripheral and twilight vision

retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions

the theory that the retina contains three diff color receptors

which color receptors does the trichromatic theory suggest

the theory that opposing retinal processes enable color vision

ex. some cells stimulated by greed and inhibited by red

the chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea's oval window

the part of the ear that contains the cochlea, semicircular canals, and vestibular sacs

coiled, bony, fluid-filled tube in the inner ear

outer ear

bones in the middle ear

hair cells in the cochlea do what
