Auditory cortex specifically attenuates responses to frequently repeated sounds

Evidence

Spectral adaptation may also be caused, at least partly, by central brain processes. Adaptation in the central hearing system appears to be stronger and to have a longer time constant (Holt, 2006; Ulanovsky et al., 2003, 2004; Watkins, 1991). This effect is assumed to occur at the level of the auditory cortex, and it is called stimulus-specific adaptation, which is the specific decrease in the response to a frequent (standard) stimulus (Holt, 2006). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1254
