Now, what's happening is that as transistors are getting seamllr and smaller and smaller, they no longer behave like this. In fact, they are starting to behave like the device that neurons use to cpmoute, which is called an ion channel. And this is a little pteoirn molecule. I mean, neurons have thdnsoaus of these. And it sits in the membrane of the cell and it's got a pore in it. And these are individual potassium ions that are flowing through that pore. Now, this pore can open and close. But, when it's open, because these ions have to line up and flow through, one at a time, you get a kind of sporadic, not steady — it's a sporadic flow of current. And even when you colse the pore — which nrnoues can do, they can open and close these pores to generate electrical activity — even when it's closed, because these ions are so small, they can actually sneak through, a few can sneak through at a time. So, what you have is that when the pore is open, you get some current sometimes. These are your ones, but you've got a few zoers thrown in. And when it's coseld, you have a zero, but you have a few ones trowhn in.

Now, what's happening is that as transistors are getting _______ and smaller and smaller, they no longer behave like this. In fact, they are starting to behave like the device that neurons use to _______, which is called an ion channel. And this is a little _______ molecule. I mean, neurons have _________ of these. And it sits in the membrane of the cell and it's got a pore in it. And these are individual potassium ions that are flowing through that pore. Now, this pore can open and close. But, when it's open, because these ions have to line up and flow through, one at a time, you get a kind of sporadic, not steady — it's a sporadic flow of current. And even when you _____ the pore — which _______ can do, they can open and close these pores to generate electrical activity — even when it's closed, because these ions are so small, they can actually sneak through, a few can sneak through at a time. So, what you have is that when the pore is open, you get some current sometimes. These are your ones, but you've got a few _____ thrown in. And when it's ______, you have a zero, but you have a few ones ______ in.

Original Text

Now, what's happening is that as transistors are getting smaller and smaller and smaller, they no longer behave like this. In fact, they are starting to behave like the device that neurons use to compute, which is called an ion channel. And this is a little protein molecule. I mean, neurons have thousands of these. And it sits in the membrane of the cell and it's got a pore in it. And these are individual potassium ions that are flowing through that pore. Now, this pore can open and close. But, when it's open, because these ions have to line up and flow through, one at a time, you get a kind of sporadic, not steady — it's a sporadic flow of current. And even when you close the pore — which neurons can do, they can open and close these pores to generate electrical activity — even when it's closed, because these ions are so small, they can actually sneak through, a few can sneak through at a time. So, what you have is that when the pore is open, you get some current sometimes. These are your ones, but you've got a few zeros thrown in. And when it's closed, you have a zero, but you have a few ones thrown in.
