Eye blink frequency eeg
WebPeople blink anywhere from 1-60 times per minute, and it’s important for the health of the eye. A Miami eye doctor may have to prescribe someone with a low blink frequency … Webcan be confused with slow EEG activity such as theta and delta rhythms. Apart from eye movement, eyelid movement (‘blink’) also affects the corneal-retinal potential difference, hence, causes EEG artifact. Different from eye movement artifact, eyelid movement produces a more abruptly changing waveform, hence, high-frequency components are
