Hide Your Brains


The era of the omnicortex is upon us, and by upon us I mean it's coming for you, and your brain.
 
Mini-brains reveal how mitochondrial mutations affect brain cells

Mini-brains, aka Brain Organoids. That is all.

Researchers achieve success in allowing a patient to 'speak' using only the power of thought
Jul 2024, phys.org

(Epilepsy patients) In the first stage of the experiment, with the depth electrodes already implanted in the patient's brain, researchers asked him to say two syllables out loud: /a/ and /e/ while they recorded brain activity. Researchers then trained AI models to identify the specific brain cells whose electrical activity indicated the desire to say /a/ or /e/. Once the computer learned, he was asked to only imagine... The computer then translated the electrical signals...

Artificial imagination with the 'exocortex:' Researcher proposes software to aid scientific inspiration and imagination
Jan 2025, phys.org

The conceptualized exocortex will be an extension of a scientist's brain.

Maybe you just want to know that Brookhaven is doing this, that's all.

'DeepFocus' offers minimally invasive brain stimulation through the nose
Feb 2025, phys.org

"By going through the nose, we can place electrodes as close to the brain as possible without opening the skull."

And that's all you need to know.
