متن کاملMismatch negativity in patients with (central) auditory processing disorders.
UNLABELLED Mismatch Negativity (MMN) is a long-latency auditory evoked potential that provides an objective index of discrimination skills and auditory sensorial memory. It may, therefore, be used as an electrophysiological evaluation of central auditory processing. AIM To study MMN in patients with Central Auditory Processing Disorder - CAPD. STUDY METHOD A prospective clinical study. MA...
