Neural responses and N20m amplitude
MINAMATA DISEASE
The P20m rate and non-response rate were significantly higher in patients with MD than in controls on either side, despite adjustments for multiple comparisons via Bonferroni correction (p < 0.0001) (Comparisons of MEG findings between controls and patients with MD. Patients with MD demonstrate significantly higher non-response rates and P20m rates than controls on either side (p < 0.0001). The N20m amplitudes, cross-correlation value, and power strength of induced gamma oscillations were significantly lower in patients with MD than in controls on either side (p < 0.0001). Bars and error bars indicate mean and standard deviation, respectively. MEG = magnetoencephalography; MD = Minamata disease.Compared with that in the control group, the average N20m amplitude in patients with MD was decreased on either side (Amplitude and dipole direction of N20m. Compared with those in controls, the average N20m amplitudes in patients with MD were significantly decreased on either side
