After moving to Barcelona, he learned Golgi’s method, which employed potassium dichromate & silver nitrate to randomly stain a few #neurons a dark black color, while the other cells remain transparent. He improved upon the method, & used it to investigate the central nervous system, which would otherwise be too densely intertwined for standard microscopic inspection. He made many extensive, detailed & beautiful illustrations of neural material for many species & 🧵4/5

"[T]ouch concerns a smorgasbord of stimuli, including pokes, pulls, puffs, caresses and vibrations, as well as a range of temperatures and chemicals, such as capsaicin in chili peppers or menthol in mint. From these inputs arise perceptions of pressure, pain, itchiness, softness and hardness, warmth and cold, and the awareness of the body in space."

Quanta Magazine · Touch, Our Most Complex Sense, Is a Landscape of Cellular Sensors | Quanta MagazineEvery soft caress of wind, searing burn and seismic rumble is detected by our skin’s tangle of touch sensors. David Ginty has spent his career cataloging the neurons beneath everyday sensations.

200,000 brain cells in a volume of 1 cubic mm.

"Researchers have created the largest and most detailed wiring diagram of a mammalian brain to date, by mapping cells in a cubic millimetre of a mouse’s brain tissue. In a landmark achievement, the diagram also details the activity of individual neurons on a large scale ― a neuroscience first."

The discovery of ‘ovoid cells’ is transforming our understanding of memory and may pave the way for new treatments for Alzheimer’s disease, epilepsy, and other neurological conditions.

These highly specialized neurons activate each time we encounter something new, triggering a process that stores those objects in memory and allowing us to recognize them months—potentially even years—later.

A brand-new horror just dropped, the CL1 is the first computer with a chip that has neurons from lab grown brains integrated into it. The case has a built-in life support system (of course there are already people who shoehorned ChatGPT on it, because AI nonsense can't be far behind).

Thankfully, the high price point will keep it out of the general consumer market...The dystopia future is coming in hot still.

I honestly dislike this abomination and find it fascinating at the same time; it's also another step in cybernetic enhancement.

Figuring out how to keep brain cells active and healthy outside the body. In the future, what can be learned from this process of keeping brain cells alive outside a person's body could be applied in other situations. Like a person who is mostly chrome, except for the brain and perhaps a few other body parts.
