Psychology

Structures such as the lens of the eye, that modify a stimulus

The process of converting incoming energy into neural activity.

Specialized cells that detect certain forms of energy and transduce them into nerve cell activity.

The process through which responsiveness to an unchanging stimulus decreases over time.

Translating the physical properties of a stimulus into a pattern of nerce cell activity that specifically identifies those properties.

The discovery that stimulation of a particular sensory nerve provides codes for that sense, no matter how the stimulation takes place.

A repetitive fluctuation in the pressure of a medium, such as air.

The difference between the peak and the baseline of a waveform.

The distance from one peak to the next in a waveform.

The number of complete waveforms, or cycles, that pass a given point in space every second.

A psychological dimension of sound determined by the amplitude of a sound wave.

The mixture of frequencies and amplitudes that make up the quality of sound.

A membrane in th emiddle ear that generates vibrations that match the sound waves sriking it.

A fluid-filled spiral structure in the ear in which auditory transduction occurs.

The floor of the fluid-filled duct that runs through the cochlea.

The bundle of axons that carries stimuli from the hair cells of the cochlea to the brain.

How high or low a tone sounds.

The ability to identify the musical notes associated with specific sound frequencies.

The area in the brain's temporal lobe that is first to receive information about sounds from the thalamus.

A theory that hair cells at a particular place on the basilar membrane respond most to a particular frequency of sound.

Electromagnetic radiation that has wavelength of approximately 400 to 750 nm

A physical dimension of light waves that refers to how much energy that light containsit determines the brightness of light.

The distance between peaks in light waves.

The curved, transparent, protective layer through which light rays enter the eye.

An opening in the eye, just behind the cornea, through which light passes.

The colorful part of the eye, which constricts or relaxes to adjust the amount of light entering the eye.

The part of the eye behind the pupil that bends light rays, focusing them on the retina.

The surface at the back of the eye onto which the lens focuses light rays.

The view that some sounds are coded by matching the frequency of neural firing.
