Fig. 2: Results of the MEG auditory evoked response to 500-ms duration 40 Hz tone bursts.

From: A multimodal magnetoencephalography 7 T fMRI and 7 T proton MR spectroscopy study in first episode psychosis

a Mean amplitude as a function of time for both FEP (red lines) and HC (blue lines) for both left and right auditory cortices. The time at which the audio stimuli began and ended are indicated by vertical dashed lines. The mean time courses of the curves for HC and FEP are similar. b RMS power at 40 Hz for the evoked (time-averaged phase-locked to stimulus onset) responses. Each red cross represents the mean value for one FEP, and each blue circle represents the mean value for one HC. There was not a significant difference between the HC or FEP by t-test (p-values given about each plot). c, d Plots arranged as in b, only for the event-related spectral perturbation (ERSP) and the phase locking factor.
