Today in @NatureNeuro, researchers led by @LabNowakowski, @ChangLabUCSF & Mircea Teodorescu (@ucscgenomics) demonstrate the first use of optogenetics to modulate seizure activity at the network level in human brain tissue:

New study connects two brain organoids with an axon bundle!
They found evidence of communication between organoids, leading to more complex neural activity.

Neuralink's "Blindsight" implant probably won't look like early Nintendo graphics: youtube.com/watch?v=-MajZf…

@cb_doge @neuralink I should mention that the Blindsight implant is already working in monkeys. Resolution will be low at first, like early Nintendo graphics, but ultimately may exceed normal human vision. (Also, no monkey has died or been seriously injured by a Neuralink device!)

The first human received an implant from @Neuralink yesterday and is recovering well.
Initial results show promising neuron spike detection.

In psychology 96% of published tests of hypotheses find support for their hypothesis. This means that as a scientist you need a solid understanding of bias - how to detect it, and what to do about inflated effects - if you want to evaluate claims in the scientific literature.

I have had an experience with one patent holding company that refused to provide a 2a blocker they held because the design I proposed threatened to support the hypothesis that 2a action & the psychedelic experience causally mediates response in depression.

This is quite a paper on AI and scientific research!
The authors got GPT-4 to autonomously research, plan, and conduct chemical experiments, including learning how to use lab equipment by reading documentation (most were operated by code, but one task had to be done by humans)

The thing about LLMs that make them unintuitive is that analogizing them to having a scifi AI is less useful than thinking of them as infinite copies of some guy named Steve, a grad student who is great at coding & art and is widely-read, but makes up stuff when he is pressed.
