Comparison between EEG and MR data. (a) Signal power decrease (0–5 Hz) between PRE and TTX states, for MR magnitude (+), and MR phase (Δ) vs. EEG (n = 5, plus control). (b) Spectral center frequency (spectral centroid 0–5 Hz) for MR magnitude (+) and MR phase (Δ) vs. EEG (n = 5, plus control). The control experiment was performed with no culture on the MEA, but all other conditions were identical.
