comment Why does strenous exercise cause vision of “lights”?
interesting that you see hexagonal shapes. Hexagons often appear in 2D sensory processing due to its relation to sphere packing.

revised Does a neuron ever generate an action potential without stimuli?
removing the disclaimer. I feel confident that my answer is better.

well balanced feedback loops create oscillations as well...

@WYSIWYG I think you should write a longer answer if you have time. :)

comment Hair loss in a submarine?
The question is not clear. Can you improve it by providing more context and writing out what you are asking? Specifically, are you talking about nuclear submarines?

comment How does strength of a pulse related to EKG(ECG)?
Great suggestions. Yes, we are interested in the normal heart. I'll test with your suggestions. Thank you.

The paper you shared could be very useful. Thank you again.

comment How does strength of a pulse related to EKG(ECG)?
Thank you for the detailed response! We have a setup where surface of cortex is imaged at high speed, and the image is contaminated by the displacement of the brain. This displacement significantly varies per beat, and we want to remove the effects. EKG and the video are pretty much all we are measuring.

comment How does strength of a pulse related to EKG(ECG)?
Thanks for the response. Hypertrophy would be a long term effect, right? I am interested in beat-to-beat variability. Do you have a reference for this by any chance? We are sure that it is the displacement of brain due to the heartbeat, and the displacement varies from beat-to-beat. We wish to control it as much as possible, but just wondering if there are better features in ECG that can be used to do so.

comment How does strength of a pulse related to EKG(ECG)?
@MCM to me it's not a matter of granularity, but fundamental plausibility. I can always improve signal-to-noise ratio, and do signal processing to improve the readings. But is there any signal related to beat strength at all?
