Why brain implants are more than a sci-fi fantasy

Well, that's probably been the worst day for #Depression of the whole bloody year, but I did not get nothing done.
I finished an essay, and I think it's an important one.

Hydraulic brain: Body motion linked to fluid movement in the brain
The brain is more mechanically connected to the body than previously appreciated, scientists report in Nature Neuroscience. Through a study using mice and simulations, the team found a potential biological mechanism underlying why exercise is thought to benefit brain health: abdominal contractions compress blood vessels connected to the spinal cord and the brain, enabling the organ to gently move within the skull. This swaying facilitates the surrounding cerebrospinal fluid to flow over the bra…

"none of these legacy behaviours are rational. They arise out of that bundle of behaviours inherited from our two billion years of sexually selected ancestors... If our ancestors had not had these behaviours, we would not be here. Our ancestors were not, in the sense we mean here, rational... A purely rational being — a being created ab initio rational — would not have these behaviours.

Intermittent fasting triggers surprising changes in the brain
Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans also revealed changes in regions tied to appetite, cravings, and self-control. The results suggest the gut microbiome and brain may work together to influence weight-loss success.

"But, given that this new research also reports that this additional brain-fluid sloshing includes an increased flow of electrolyte ions like sodium and potassium, I’m going to go ahead and give you permission to think of this as your brain swishing salt water around to clean itself up.

The brain region associated with moral inconsistency
Why don't some people practice what they preach? Researchers reveal that a brain region called the ventromedial prefrontal cortex (vmPFC) is involved. The researchers used fMRI imaging to identify brain activity patterns associated with moral behavior and judgment. People who behaved dishonestly despite judging the same behavior as immoral in others had less activity in the vmPFC, and when the researchers stimulated participants' vmPFCs, they became more morally inconsistent.

Everyone should listen to this week’s Hidden Brain (NPR.)
Some academic named Dave is making the solid case for “radical acceptance “ grounded in design thinking.
I concur with his core argument: reality is the only place where anything can work. Seems like a good place to start, to accept it. That doesn’t mean endorsing reality, just that we live in a broken world and should try to skip the “stages of grief “ in navigating adversity.

A new study helps explain how the brain creates mental images

One of those things about claims of “AGI” is that to really build a human-like intelligence we’d have to simulate a human brain as whole because 1. it’s the only thing we know that produces human intelligence and 2. no one knows how it actually works.
Because of (2) it’s irrelevant what anyone says about LLMs or any other technology (with the exception of simulating a whole brain)—you can’t know if a technology is intelligent like a human because we don’t know what that means or how that works.
Fun thing, it turns out it’s impossible to simulate a whole brain with the resolution required (basically quantum physics level), and you’d have to emulate a chemical and physical environment for the brain as well (it will also need a body etc.).
You’d also have to simulate other humans with brains from which the brain can learn; but to simulate those you’d have simulate evolving humans from single-cell organisms first etc etc ad infinitum
