List and define the four major receptor groups.

The ion channels that transduce the vibration of the cochlea into receptor potentials are located on the

Match the ganglion cell response to the location of the light stimulus. -Light only shines on the center of an on-center visual field.

________ is the fluid within the vestibular and tympanic duct of the cochlea.

Describe pitch and loudness and how these are properties of sound are processed by the cochlea.

The highest frequency sound is detected by

Signal transduction in the type II taste cells relies on the G protein

Match the ganglion cell response to the location of the light stimulus. -Light only shines on the center of an off-center visual field.

The loudness or intensity of a sound wave is related to its

A decrease in ones perception of a stimulus whose intensity has not changed due to higher neural inhibition is

Explain how sensory coding and processing allow the central nervous system to communicate information on the four properties of a stimulus.

Describe how lateral inhibition allows for localization of a stimulus.

Months after the accident,your amputee uncle's phantom limb pain subsides.One afternoon he is sleeping and you see a fly walk across his upper lip.He wakes up and tells you he just had the funniest feeling.It was as if someone was touching his missing index finger.You decide to experiment with your uncle and you blindfold him.As you touch his cheek he tells you that you are touching his cheek and his missing thumb! As you move around his face you map out his fingers and forearm on his face.Hypothesize how this could be possible.
