I'm looking at an output of a single dry sensor EEG headband with the sensor positioned above left eye. As a side effect of it's placement, the device picks up eye blinks, and some eye motion as changes in the amplitude of the raw output waveform. It is clearly visible, and I can probably detect it algorithmically.
My question is - does frequency of eye blinking (not controlled) reveal anything about the state of (autonomous?) nervous system, or processes that take place within the brain? For example, what is the difference between blinking involuntary X times per minute versus Y times per minute for the same individual? Does blinking get suppressed in response to some stimuli, like loud noises, speech, etc?
I appreciate your input!
