Quiz 7 Ch 9
we are most sensitive to sounds between
1000Hz - 4000Hz
a lesion of the angular gyrus would most probably result in
alexia
Which of the following refers to the inability to name objects
anomia
the ___________ equalizes the air pressure of the middle ear with the outside world
eustachian tube
mirror neurons are most active during
imitation of another's movement
which of the following are binaural cues?
interaural intensity difference, interaural timing difference
in the auditory system hair cells are specialized receptors that respond to:
mechanical displacement
the highest frequency sounds stimulate hair cells
near the base of the basilar membrane
tonotopically organized means
neurons from adjacent receptor locations project to adjacent cells in the cortex
what occurs to a tone as the frequency increases?
pitch gets higher
the _________ theory says that encoding sound frequency depends on the location of maximal vibration on the basilar membrane
place
people with massive damage to the primary auditory cortex cannot
recognize combinations or sequences of sound
phenomes are
small units speech that distinguish one word from another
someone with Broca's aphasia has the greatest difficulty
speaking
to what love of the cerebral cortex is auditory information sent?
temporal
according to frequency theory
the basilar membrane vibrates in synchrony with a sound, producing action potentials at same frequency
the tympanic membrane vibrates at
the same frequency as the sound waves that hit it
someone suffering from Wernicke's aphasia as difficulty
understanding speech
