Optical imaging of cat auditory cortical organization after electrical stimulation of a multichannel cochlear implant: differential effects of acute and chronic stimulation.
OBJECTIVE
To study the effects of electrical stimulation on cortical activation patterns.


METHODS
Optical imaging of auditory cortex in cats that are acutely and chronically electrically stimulated with cochlear implants.


RESULTS
Chronic electrical stimulation results in expansion of cortical territory and overlap.


CONCLUSIONS
Effects of chronic electrical stimulation are comparable to use-dependent cortical plastic reorganization.
