There's a wonderful cartoon in the Rockefeller University bar shows two guys sitting by a campfire on. I forget the exact caption, but it goes something like it. Yeah, Jones invented fire. What's he done lately? That's that is the question that keeps her body us foot. Brain surgery is carried out effort to control epilepsy, and the idea by the surgery was very simple. But there would be a seizure starting in one hemisphere and then by dividing the comma. Sure that connects the two have brains. A seizure would be limited to that theme. The Left Hemisphere remained dominant for language and speech. If I put an apple in the right hand, the left hand would immediately say it's an apple. The left brain would say it's an apple because the information goes to the left brain. The speeches in the left brain. It's an apple. Then he would literally just put the apple in the left hand, which sends the information about what it is to the right brain. And you would hear the patients say, I don't know what it is. Anything Well, you know, I don't know. I don't know what's in my hand. We had identified a fiber system that obviously communicates the information that is so crucial for our mental life. With that, we could figure out the code of the neural code of high level information because we just was there. But we knew that was where the information was crossing in the brain. So I went off for a postdoctoral fellowship in Italy with famous lab of Josephine Maroussi. And there were two young guys there, Jack, more resolute in Germany. Burn. Okay. And we all got set on the idea that we were gonna electrode in a cat and we in this area, and we were going to discover how information was coated in the brain. I mean, it was that blatantly naive. And so the big day comes on, all we've done, all the preparations and fine tune the recording system have the visual display systems for the animal, all the rest of it, and the speakers air on in the room. And so that you can hear, we could We're going to hear the neurons firing in Morse code that, you know, forget we're thinking Anyway, the electrode is big lower down into cats, corpus callosum and just as the electrode touches the corpus callosum over the speaker system, we're all waiting in great anticipation over the speaker system comes a fine playing of the Beatles. We all live in a yellow submarine. It was just a clear as a bell electro became sort of picked up like antenna became just the song that was playing locally and Pisa system. It's crazy that pipe dream was over with. Now the hard work. What does this thing do? Let's attack scientifically. And we did and rather nice study at my say, Those guys think just remind you, you can launch into a project with a simple idea you cooked up kind of the night before in the bar. You know, something bad is that and and then you Then you start, you get your driven by. You really want to know more about it, and then you you get into the hard science of it, that you reframe it. Then you tighten it down and so forth and so on. During my junior year, I was reading an article on how there is a group but Roger Sperry and it was a Scientific American article, and it was fantastic And so I throw the later on. I said, uh, experience live in California, next to Caltech. Is there any chance of a summer fellowship? Just total shot in the dark red. And within a week, I got a letter back. Well, yes, we have these ships. Why don't you come on over and spend the summer here? So I did. And I was looking for The great thing about Caltech was the frequency with which you would run into somebody who was one of the top people in biology or physics or whatever and complete realization that they actually cared about the students where I was, sir. Parties factually always came one night Feinman was there on, uh, So by that time, I was deep into the split brain research, and it was known that I was the guy, the kid that did the research on this foot brains. And so he was leaving the party, and I was standing by the door, and he comes up to me. He says if you can guarantee I can do physics after split brain surgery, I'll let you do surgery on me, and I said, I guarantee it and he says Okay. Thank you. Supple Shakes shakes my book Both my any laughs. Life in science is not like a rock star that gets a hit. Maybe there's a transformation that there's a contracts and there's, you know, shows and it just doesn't work that way. Can't keep singing that song. You've got to come up with more dimensions to it and look a greater questions. And but lovable. I think everybody wants to know whether ultimately you are to be held accountable for your actions. How would we think about this problem, given what we know, what the brain does and what the biologic system does, what social interactions dio with levels of organization We're talking. Just start thinking of fresh about it. I think you're pretty pretty quickly Get rid of the notion that free will is an important idea. What's important is holding onto the notion of how you how we humans are going to be held responsible for actions. There's something violating that concept, and I say, No, there's not, Yeah, we've looked at this problem incorrectly for a lot of years. That's my strong argument, and we'll see where it goes
