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) .
