We account for all of that. We have higher quality equipment to reduce device delays.

Are you sure you aren’t “predicting” ?

Also I really question how accurate the website is. Has it done latency tests on your screen and keyboard and accounted for that? Because maybe it’s using the wrong information and adjusting your score out of humanly possible ranges.

I say this because it takes nearly 150-250 ms just for the visual stimuli to be processed. There is no way around this. en.wikipedia.org/wiki/P200

There are specific processes that occur in the brain that take time to happen. And these are dependent on size of the brain (a very small factor within same specifics,) and myelination. A much bigger factor even within species.

Myelination is essentially the lubricant and insulation for signal wires. Signal travels faster and in higher quality when neuron connections are adequately myelinated.

This is something mostly genetic but can be degraded with diseases like MS and aging.

Of course having stronger pathways from using those pathways often will make them more accurate.

Motor control is , in many ways, the most simple processes the brain does. It’s not that simple. But compared to a lot of other functions it is.

Motor Pathways are mostly mapped out in humans. However, We still don’t understand completely what the cerebellum does but it’s very involved in motor control. (Not initiation tho). Because of the straight forward nature tho of initiating a response we know those hard limits of reaction time for pushing a button after seeing or hearing a stimuli signal.

The best thing for your brain is adequate, efficient, and reactive oxygen supply.

Meaning the heart and vascular system can re route oxygen quickly to various brain areas in response to need.

People want magic vitamins and neurotropic drugs to make themselves smarter but in reality, cardiovascular health is literally number 1.
