A short period during which the multichannel EEG scalp potential topography remains relatively stable.\nB. The scalp projection of a single action potential from one pyramidal neuron.\nC. A sleep stage within one complete sleep cycle.\nD. An eye-movement component removed after ICA decomposition." | |
