Single-trial analysis of P20m and absent N20m peak
We examined the frequency of P20m epochs, N20m amplitude of averaged SEFs in N20m epochs, and P20m amplitude of averaged SEFs in P20m epochs in controls and patients with MD with the P20m or an absent N20m peak. The controls displayed fewer P20m epochs, and the averaged sensor SEFs and averaged SEFs of the N20m epochs nearly overlapped (Single-trial analysis of P20m and absent N20m peak. Left diagrams depict the cross-correlation of each epoch. Right diagrams depict the averaged sensor SEFs (black line), averaged SEFs of N20m epochs (blue dashed line), and P20m epochs (red dashed line). The controls exhibited fewer P20m epochs (left diagram), and the averaged sensor SEFs and averaged SEFs of the N20m epochs almost overlapped (right diagram)
