Chapter 6 Flashcards
Three small bones connect the temp Hannick membrane to the oval window what is the function of these bones
They convert airwaves into waves of greater pressure
What sound characteristics can be compared between the two ears to locate the source of the sound
Loudness and timing
Perception of a low tone is to_____ as perception of a high tone is to _____
Frequency theory place theory
A tonotopic map refers to
Auditory cortex map of sounds
According to the frequency theory the
Basilar membrane vibrates and synchrony with the sound producing action potential’s at the same frequency
The current view of how we perceive high frequencies is based on
Where along the basilar membrane neurons fire most rapidly
The ______ of a sound is the number of compressions per second
Frequency
Patients with damage in area MT have problems with perception of
Movement of objects and sounds
Where are the auditory receptor cells located
On the basilar membrane
The fact that the refractory period limits the firing rate of a neuron is problematic for which of the following
Frequency theory only
The eardrum vibrates at
The same frequency as the sound waves that hit it
Vibrations in the fluid of the cochlea causes
Hair cells to displace
