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
