|
inner hair cells/outer hair cells- efferent/afferent?
|
inner hair cells are afferent (to the brain)
outer hair cells are mostly efferent (from the brain)- convey information from the brain and involved in elaborate feedback system |
|
|
more intense coding?
|
tympanic membrane moves farther in and out, causing a chain reaction leading to a high firing rate of afferent neurons
|
|
|
frequency coding
|
high frequencies close to base
low frequencies close to apex |
|
|
what localizes sound for high frequencies vs. low frequencies
|
high frequencies: intensity
low frequencies: phase |
|
|
inverse-square law
|
as distance from a source increases, intensity decreases faster such that decrease in intensity is distance squared
