I want to Record an eye blinking waveform signal from EEG signals , but it need to make a quiscent periods of recording , So how to make this quiescent periods(i.e the signal has a zero amplitude at all time in the quiescent recording except the eye blinking time)?
Record an eye blinking waveform signal from EEG signals
eeg;signal detection
You can't. Flatline EEG is how brain death is defined, and while it may be possible to induce an eye blink in a deceased human, I am sure ethics will not approve, and it won't be scientifically satisfactory. even in the case of a real flatline EEG, there will always be some remaining residual activity (albeit very weak), such as line noise. However, the eye blink is a few orders of magnitude stronger than the ongoing EEGyou can isolate eye blink activity using techniques such as ICA
