Brain and the Ear Flashcards
Apex of the Cochlea
Helicotrema: for low frequency sounds
Base of the Cochlea
high frequency sounds
Vestibular Canal
Top canal of the Cochlea, where sound goes in
Tympanic Canal
bottom of the Cochlea, where sound comes out
Basilar membrane
division between the vestibular and tympanic canal. The bottom of the organ of corti.
Tonotopic mapping
the idea that neural activity to frequency response occurs due to physical stimulation of a particular critical band on the basilar membrane.
Reissner’s Membrane
Top of the organ of Corti, above which is the vestibular canal.
Tectorial Membrane
the tips of the outer hair cells are embedded in this. is found within the organ of Corti.
Cochlear Nucleus
sound localization and identification
Superior Olivary Complex
ITD and ILD processing
Lateral Lemniscus
sound localization and identification
Inferior Collisculus
extraction of amplitude and pitch information
Primary Auditory Cortex
primary auditory cognition. melody, harmony, rhythm and meter
