Auditory System: Cortical Plasticity
•
Damage to hair cells in cochlea: remaps
neighboring frequencies in the cortex.
•
Train to discriminate tones: increases area
of trained frequency in cortex.
•
Conditioning: pairing tone with stimulus
•
Mechanism: corr with ACh release ?
•
Pair a tone (9 kHz) with electrical
stimulation of Nucleus Basalis (ACh) .
