disrupt normal thought processes

How do psychoactive drugs work?

The detection, by sense organs, of physical energy emitted or reflected by physical objects

The process by which the brain organizes and interprets sensory information

specialized cells that convert physical energy in the environment or body to electrical energy that can be transmitted as nerve impulses to the brain

the principle that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain

a condition in which stimulation of one sense also evokes another

vividness or purity of color

lightness or luminess

neural tissue lining the pupil and lens and is focused in the retina at the back of the eye

a process by which visual receptors become maximally sensitive to dim light

Neurons  in the retina of the eye, which gather information from receptor cells; their axons make up the optic nerve

cells in the visual cortex that are sensitive to specific features of the environment

a theory of color perception that assumes that the visual system treats pairs of colors as opposing

the turning inward of the eyes which occurs when they focus on a nearby object

the slight difference in lateral separation between two objects as seen by the left eye and the right eye

visual cues to depth or distance, which can be used by one eye alone

visual cues to depth or distance requiring two eyes

the accurate perception of objects as stable of unchanged despite changes in the sensory patterns they produce

the distinguishing quality of sound

a structure in the cochlea containing hair cells that serve as receptors for hearing

a snail-shaped, fluid filled organ in the inner ear, containing the organ of Corti, where the receptors for hearing are located

nests of taste receptor cells

knoblike elevations on the tongue; containing the taste buds

the theory that the experience of pain depends in part on whether pain impulses get past a neurological "gate" in the spinal cord and thus reaches the brain

the experience of pain in the missing limb or other body part

the sense of  body position and movement of body parts

the sense of balance

sense organs in the inner ear that contribute to equilibrium by respond to the rotation of the head

a habitual way of perceiving, based on expectations
