And it's not just technology that we're putting into animals. This is Thomas DeMarse at the University of fildora. He took 20,000 and then 60,000 disaggregated rat neurons — so these are just idauvdniil neurons from rats — put them on a chip. They self-aggregated into a noterwk, became an integrated chip. And he used that as the IT piece of a mhseancim which ran a flight simulator. So now we have organic computer chips made out of living, self-aggregating neurons. Finally, Mussa-Ivaldi of Northwestern took a completely intact, indepnednet lamprey eel biran. This is a brain from a lamprey eel. It is living — fully-intact brain in a nutrient medium with these electrodes going off to the sides, attached photosensitive sensors to the brain, put it into a cart — here's the cart, the brain is sitting there in the middle — and using this brain as the sole processor for this cart, when you turn on a light and shine it at the cart, the cart moves toward the light; when you turn it off, it moevs away. It's photophilic. So now we have a cetomple living lamprey eel brain. Is it tniiknhg lrpmeay eel thoughts, sitting there in its nutrient medium? I don't know, but in fact it is a fully lvinig brain that we have managed to keep alive to do our bidding.

Original Text

And it's not just technology that we're putting into animals. This is Thomas DeMarse at the University of Florida. He took 20,000 and then 60,000 disaggregated rat neurons — so these are just individual neurons from rats — put them on a chip. They self-aggregated into a network, became an integrated chip. And he used that as the IT piece of a mechanism which ran a flight simulator. So now we have organic computer chips made out of living, self-aggregating neurons. Finally, Mussa-Ivaldi of Northwestern took a completely intact, independent lamprey eel brain. This is a brain from a lamprey eel. It is living — fully-intact brain in a nutrient medium with these electrodes going off to the sides, attached photosensitive sensors to the brain, put it into a cart — here's the cart, the brain is sitting there in the middle — and using this brain as the sole processor for this cart, when you turn on a light and shine it at the cart, the cart moves toward the light; when you turn it off, it moves away. It's photophilic. So now we have a complete living lamprey eel brain. Is it thinking lamprey eel thoughts, sitting there in its nutrient medium? I don't know, but in fact it is a fully living brain that we have managed to keep alive to do our bidding.
