Description:
Sensitivity to acoustic invariance is critical for establishing stable representations in a shifting world of sound. By recording early auditory cortical responses to complex sounds in human listeners and categorising these responses according to the maintenance or change of stimulus attributes across consecutive presentations, we show that repetition within a constantly varying acoustic context produces enhanced neural responding in auditory cortices.
