DESCRIPTION:The brain response to sensory stimuli decreases when those sti
 muli are repeated. This repetition suppression\, or adaptation\, is one of
  the most robust and ubiquitous features of neural sensory processing\, an
 d seems to be particularly prevalent in auditory processing. This talk inv
 estigates the mechanisms and functional significance of adaptation in huma
 n auditory cortical processing. I will present evidence from electro-encep
 halography (EEG) suggesting that adaptation enables the brain to extract s
 tatistical regularities in auditory input\, which are used to fade out the
  acoustic “background” and enhance sensitivity to novel or unexpected 
 events.\n\n
