System by which information about different frequencies is coded by different locations on the basilar membrane.

30
Q

Cochlear implant

A

Electronic device surgically implanted in the inner ear that can enable a deaf person to hear.

31
Q

Rate code

A

System by which information about different frequencies is coded by the rate of firing of neurons in the auditory system.

32
Q

Fundamental frequency

A

Lowest, and usually most intense, frequency of a complex sound; most often perceived as the sound’s basic pitch.

33
Q

Overtone

A

Frequency of complex tones that occurs at multiples of the fundamental frequency.

55
Q

Umami

A

Taste sensation produced by glutamate.

56
