Iris

a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.

100

Ear canal

 The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs

100

touch

The sense of touch is really a collection of several senses, encompassing pressure, pain, cold, and warmth.

100

Anatomy of the Eye Cont. 

Optic disc

The nerve that carries neural impulses from the eye to the brain.

100

Gestalt

An organized whole. Just thought psychologists emphasize our tendency to integrate pieces of information into meaningful wholes.

200

Lens

the transparent structure behind the pupil that changes shape to help Focus images on the retina.

200

Eardrum

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

200

smell

the faculty or power of perceiving odors or scents by means of the organs in the nose.

200

Torsten Wiesel

Along with David Hubel discovered feature detector groups of neurons in the visual cortex that respond to different types of visual images

200

Depth perception

the ability to see objects in three dimensions although the images that strike the retina are two dimensional, allows us to judge distance.

300

Pupil

The adjustable opening in the center of the eye through which light enters.

300

Semicircular canals

three tiny, fluid-filled tubes in your inner ear that help you keep your balance

300

Anatomy of the Ear Cont. 

Vestibular nerve

sends balance and head position information from the inner ear to the brain.

300

Ernst Weber

just-noticeable-difference (JND) that eventually becomes his law; Studies: 1st study on JND

300

Top-down processing

Information processing Guided by higher-level mental processes, as when we construct perceptions drawing on our experiences and expectations.

400

Cornea

The eyes clear, protective outer layer, covering the pupil and Iris.

400

Cochlea

A cold, bony, fluid-filled tube in the inner ear, sound waves traveling through the cochlear fluid trigger nerve impulses

400

taste

the sensation of flavor perceived in the mouth and throat on contact with a substance.

400

David Hubel

United States neuroscientist noted for his studies of the neural basis of vision (born in 1926)

400

Bottom-up processing

Analysis that begins with the sensory receptors and works up to the brains integration of sensory information.

500

Retina

The light sensitive inner surface of the eye, containing the receptor rods and cones + layers of the neurons that begin the processing of visual information.

500

Auditory nerve

Carries the neural messages to your Thalamus and then on to the auditory cortex in your brains temporal lobe

500

pain

physical suffering or discomfort caused by illness or injury.

500

Gustav Fechner

stated that the magnitude of a sensory experience is proportionate to the # of JND's that the stimulus causing the experiences above the absolute threshold

Anatomy of the Eye Cont. 

Optic nerve

The nerve that carries neural impulses from the eye to the brain.
