Elon Musk's Neuralink venture has demonstrated its latest developments in brain implant technology with a live display using pigs.
Viewers could see a visual representation of the activity on a screen which lit up when the neurons were stimulated, accompanied by a beep or crackling noise.
The ultimate aim of Neurolink is to allow humans with neurological conditions or brain injuries to control technology with their thoughts and some experts have told Inverse their views on the research.
Of the decision to work with pigs Mr Musk said on YouTube: "Pigs are actually quite similar to people. So if we're going to figure out things for people, then pigs are a good choice."
