Gamma band activity and the P3 reflect post-perceptual processes, not visual awareness.

Neuroimage July 22, 2014 Michael Pitts, Jennifer Padwal, Daniel Fennelly et al.

A primary goal in cognitive neuroscience is to identify neural correlates of conscious perception (NCC). By contrasting conditions in which subjects are aware versus unaware of identical visual stimuli, a number of candidate NCCs have emerged; among them are induced gamma band activity in the EEG and the P3 event-related potential. In most previous studies, however, the critical stimuli were...

Multiscale Network Disruption of Auditory-Language Circuits Underlying Auditory Hallucinations in Schizophrenia

Andrew C Murphy, Antigona Martinez, Yadi Chen et al.

Abstract: Background: Auditory verbal hallucinations (AVH) are among the most disabling symptoms of schizophrenia, yet the network-level mechanisms linking auditory dysfunction to hallucination severity remain poorly characterized, limiting targeted therapeutic development. Methods: Using resting-state fMRI and high-resolution surface-based parcellation (HCP-MMP), we examined auditory-language...
