Elon Musk now has a robot that can do neocortex circuit grafts with 1000 electrodes, but Yukiyasu Kamitani has been trying to read the brain without invasive surgery, for a while now.
“In their Sónar+D Talk, neuroscientist Yukiuasu Kamitani and multidisciplinary artist Daito Manabe explain the processes behind their groundbreaking collaborative show Dissonant Imaginary, whereby AI is used to decode brain visualisation processes.”
He shows pictures to people, while they’re in an fMRI machine, measures the magnetic waves, stores something like a pixel map, and tries to recreate the images https://www.youtube.com/watch?v=pV-PX1UNXmo
(Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled.) – https://en.wikipedia.org/wiki/Functional_magnetic_resonance_imaging
