Layer-fMRI probes the mesoscopic neural architecture in humans non-invasively. We studied the behavioral relevance of layer-specific processing by investigating temporal deviance detection in the auditory system. Preliminary results indicate increased response in superficial layers to a temporal deviant, in line with a feedback signal entering superficial layers during deviant detection.
