Experience-based auditory predictions modulate brain activity to silence as do real sounds

Chouiter, Leila ; Tzovara, Athina ; Dieguez, Sebastian ; Annoni, Jean-Marie ; Magezi, David ; De Lucia, Marzia ; Spierer, Lucas

In: Journal of Cognitive Neuroscience, 2015, vol. 27, no. 10, p. 1968–1980

Interactions between stimuli's acoustic features and experience-based internal models of the environment enable listeners to compensate for the disruptions in auditory streams that are regularly encountered in noisy environments. However, whether auditory gaps are filled in predictively or restored a posteriori remains unclear. The current lack of positive statistical evidence that internal...

Electrical neuroimaging during auditory motion aftereffects reveals that auditory motion processing is motion sensitive but not direction selective

Magezi, David A. ; Buetler, Karin A. ; Chouiter, Leila ; Annoni, Jean-Marie ; Spierer, Lucas

In: Journal of Neurophysiology, 2013, vol. 109, no. 2, p. 321-331

Following prolonged exposure to adaptor sounds moving in a single direction, participants may perceive stationary-probe sounds as moving in the opposite direction [direction-selective auditory motion aftereffect (aMAE)] and be less sensitive to motion of any probe sounds that are actually moving (motion-sensitive aMAE). The neural mechanisms of aMAEs, and notably whether they are due to...
