Is cerebellum responsible for muscle memory?
There are people without cerebellum. It affects thought and emotion. https://www.npr.org/sections/health-shots/2015/03/16/3927897...

You'd have to apply an adverse stimulus in under a ~5ms threshold to actions that were 'wrong'. It would depend on the exact task you're trying to do though. That would then cause other areas to potentiate that specific movement/firing as incorrect. Its a active area of research in sports and DoD. As you'd theoretically be able to train marksmen and athletes at a much faster and better rate. However, even really real…

The pattern of muscle activation timing in the correct move form needs to be figured out by exploration of the space.
The feedback loops are often long. Getting a review on a performance, etc.
If a device were set up to trigger pain within some milliseconds of an incorrect activation, surely we could speed this up?
This is fascinating to me. The list of things the author suggests the cerebellum handles is a tailor-made list of things I'm oddly bad at: 1. I'm very uncoordinated, with a noticeable intentional tremor 2. I'm particularly bad at sequencing dependencies for projects/errands/household tasks. I have to write down even fairly simple sequences of subtasks or get lost in yak-shaving loops 3. When flustered, I make very di…

There’s zero evidence that there’s anything more quantum mechanical about the brain than a brick. IE: Physical and chemical interactions that emerge from quantum behavior, but can be modeled just fine without QM. Instead people seem to just equate two different complex things they don’t understand with each other.
Your comment has a feel to it of a rebuttal; but I hope it's clear that the original comment has effectively this same stancen as this.

Can you provide a reference for this? I searched and found nothing.

Not really, but it can be involved for some tasks. 'Muscle Memory' is a bit of a complex thing. It's not so much the firing of the neurons, as much as it is the timing of that firing. Your reaction time is at the ~5ms level. Much longer than the muscles need to move in concert to, say, hit a 3-pointer. Controlling all of that can take place all the way from the brain down to the ganglia of the spinal chord. Drinking…
It is interesting though. Do you know if there is a name for this particular area of neuroscience?
That's an interesting perspective. While I agree that the pace of advancements in neuroscience is slower compared to AI, I think it's important to note that understanding the brain is a fundamentally different problem than building intelligent machines. The human brain is an incredibly complex system with billions of interconnected neurons, and we still have a long way to go in terms of fully understanding how it wor…
