Robot Brings Patch-Clamping To the Masses

scibri writes about robots helping neuroscientists dig into the brains of (animal) test subjects. From the article: "Robots designed to perform whole-cell patch-clamping, a difficult but powerful method that allows neuroscientists to access neurons' internal electrical workings, could make the tricky technique commonplace. Scientists from MIT have designed a robot that can record electrical currents in up to 4 neurons in the brains of anesthetized mice (abstract) at once, and they hope to extend it to up to 100 at a time. The robot finds its target on the basis of characteristic changes in the electrical environment near neurons. Then, the device nicks the cell's membrane and seals itself around the tiny hole to access the neuron's contents."

one step closer

one step closer to recording myself into a body not ravaged by television and cheetos

Die and leave a copy, or die and don't.

Yeah, there are two of me, briefly -- but one of me never wakes up after the transfer, and the other wakes up healthy.

I'm actually completely OK with this. Maybe it has something to do with a lifetime of going to sleep every night, and never failing to wake up the next day. Discontinuity of experience is nothing new.

It doesn't have to be that way. You would slowly replace parts of your brain with wetware until it was all artificial.

You would then still be "you", and not two of you.

"Plutarch thus questions whether the ship would remain the same if it were entirely replaced, piece by piece. Centuries later, the philosopher Thomas Hobbes introduced a further puzzle, wondering: what would happen if the original planks were gathered up after they were replaced, and used to build a second ship.[3] Which ship, if either, is the original Ship of Theseus?"

1) Almost nobody on /. knows about or will ever see this technique practiced

Almost nobody who knows about patch clamping practices it. It's that hard. "The masses" in this case refers to the 90% of neuroscience labs who don't have a patch clamp apparatus because it's an incredibly difficult technique. Putting an automatic patch clamp machine on every lab bench would be a huge boon to neuroscience.
