How do psychoactive drugs work?
By acting on neurotransmitters
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
doctrine of specific nerve energies
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
organ of Corti
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
