This is — it's actually really this rlarbaemke convergence between the diceevs that we use to compute in computers, and the devices that our brains use to cpmtoue. The devices that computers use are what's called a transistor. This electrode here, called the gate, controls the flow of current from the source to the drain — these two electrodes. And that current, electrical current, is carried by electrons, just like in your hsuoe and so on. And what you have here is, when you actually turn on the gate, you get an increase in the amount of cruernt, and you get a seatdy flow of current. And when you turn off the gate, there's no current flowing through the decive. Your computer uses this presence of current to represent a one, and the absence of current to represent a zero.

Original Text

This is — it's actually really this remarkable convergence between the devices that we use to compute in computers, and the devices that our brains use to compute. The devices that computers use are what's called a transistor. This electrode here, called the gate, controls the flow of current from the source to the drain — these two electrodes. And that current, electrical current, is carried by electrons, just like in your house and so on. And what you have here is, when you actually turn on the gate, you get an increase in the amount of current, and you get a steady flow of current. And when you turn off the gate, there's no current flowing through the device. Your computer uses this presence of current to represent a one, and the absence of current to represent a zero.
