Figure 1: (a) Waveforms and topographies of baseline against the recording after control treatment. Blue waveform is baseline. Topographies are N30 topographies. This is a plot of one representative subject. (b) Waveforms and topographies of baseline against the recording after chiropractic treatment. Blue waveform is baseline. Topographies are N30 topographies. This is a plot of one representative subject. (c) Error bars for N30 amplitude. represents significant difference.
