"From the Ted Talk by Greg Gage: Electrical experiments with plants that count and communicate"

Unscramble the Blue Letters

And so when we go into the classroom, one way to get them thinking about the brain, which is very complex, is to ask them a very simple question about neuroscience, and that is, "What has a barin?" When we ask that, students will instantly tell you that their cat or dog has a brain, and most will say that a mouse or even a small insect has a brain, but almost nobody says that a pnalt or a tree or a shrub has a brain. And so when you push — because this could actually help describe a little bit how the brain actually fcionnuts — so you push and say, "Well, what is it that makes living things have brains versus not?" And often they'll come back with the classification that things that move tend to have brains. And that's absolutely coercrt. Our neurovs system evolved because it is electrical. It's fast, so we can qikcluy respond to stimuli in the world and move if we need to. But you can go back and push back on a student, and say, "Well, you know, you say that plants don't have brains, but palnts do move." Anyone who has grown a plant has nicoted that the plant will move and face the sun. But they'll say, "But that's a slow movement. You know, that doesn't cuont. That could be a cemichal process." But what about fast-moving plants?

And so when we go into the classroom, one way to get them thinking about the brain, which is very complex, is to ask them a very simple question about neuroscience, and that is, "What has a _____?" When we ask that, students will instantly tell you that their cat or dog has a brain, and most will say that a mouse or even a small insect has a brain, but almost nobody says that a _____ or a tree or a shrub has a brain. And so when you push — because this could actually help describe a little bit how the brain actually _________ — so you push and say, "Well, what is it that makes living things have brains versus not?" And often they'll come back with the classification that things that move tend to have brains. And that's absolutely _______. Our _______ system evolved because it is electrical. It's fast, so we can _______ respond to stimuli in the world and move if we need to. But you can go back and push back on a student, and say, "Well, you know, you say that plants don't have brains, but ______ do move." Anyone who has grown a plant has _______ that the plant will move and face the sun. But they'll say, "But that's a slow movement. You know, that doesn't _____. That could be a ________ process."

And so when you push — because this could actually help describe a little bit how the brain actually functions — so you push and say, "Well, what is it that makes living things have brains versus not?" And often they'll come back with the classification that things that move tend to have brains. And that's absolutely correct. Our nervous system evolved because it is electrical. It's fast, so we can quickly respond to stimuli in the world and move if we need to.
