This amazing project is using rat brain neurons to control robots. Like other projects of its kind, they are finding that the neurons almost immediately seek interconnection – in some ways they appear to be pre-programmed (aka evolutionarily designed) to assemble into more advanced forms.
Unfortunately for misguided and shortsighted ethical reasons reasearches are not using human neurons, but as they note here that’s not a huge problem because our human brain cells have a lot in common with rats cells – or other vertebrates for that matter.
As Kevin Warwick, the project architect who one might call something of an “Dr A.I. Frankenstein”, notes:
…. rats brain cells are not a bad stand-in: much of the difference between rodent and human intelligence, speculates Warwick, could be attributed to quantity not quality.
Thanks to Glenn for the tip!
