Lesson 6 Flashcards
True or false? If false, correct statement
Our ears receive vibrations of air molecules varying in frequency (Hz) and amplitude.
true
loudness and pitch are related to amplitude and frequency, but not identical
sound
pure tones can have how many frequencies?
one
complex tones can have how many frequencies?
many
Two non-identical sounds can have the same loudness and pitch.
timbre
timbre depends on…
the frequency spectrum, the sound pressure and the temporal characteristics of the sound.
sound is taken to the temporal lobe but specifically what part of your temporal lobe?
human auditory cortex.
The amplitude of a sound wave is related to the _________ of a sound.
loudness
True or false? If False, correct the statement
During audition, sound vibrations are encoded as neural signals in the basilar membrane of the cochlea.
true
High-frequency sounds primarily activate hair cells at the ________ of the cochlea, whereas low-frequency sounds primarily activate hair cells at the ________ of the cochlea.
base (thicker end); apex (thinner end)
Hearing has ____ lateral and _____ lateral pathways
contra- and ipsi
Beyond Auditory Cortex, two pathways. The ventral stream is for ___ and a dorsal stream for ____/___
what; where/how
The primary auditory cortex is located in the:
superior temporal lobe
Vision is to audition as the ____________ is to the ____________.
lateral geniculate nucleus; medial geniculate nucleus
What is not TRUE about the similarities between the visual and auditory pathway:
Both visual and auditory information are processed by the hemisphere contralateral to the sensory input (i.e. the pathways are cross-wired)
