Laminar specificity of the auditory perceptual awareness negativity: A biophysical modeling study
Fig 1
Stimulation paradigm and evoked responses.
(A) Trial consisting of a sequence of standard tones (the target) embedded in a “cloud” of tones placed randomly in frequency and time (multitone masking). (B) Source locations of responses shown in C. (C) MEG activity of undetected (blue trace) and detected (orange trace) standard tones for both left and right auditory cortex. (D) Average of undetected and detected responses across hemispheres. (E) Difference waveform between the recorded response to the undetected and the recorded response to detected standard tones. Adapted from [26]. Negative is plotted down.
