The negatives cancel out.

We switch signs as we cross 3.

You can see there's some signals there.

Because the negatives cancel out.

Remember, different signs will get you a negative result.

The negatives cancel out. x is less than.

So these negatives cancel out.

The signals that you are seeing here are action potential, are the same signals that the neurons of my brain, of our brain, use to exchange information.

Well, 4 divided by 1 is 4, but the signs are different.

You've got to be real careful to get the signs right.

In this case, the negatives cancel out.

So different signs mean negative.

Then I'm going to have a 2, but I'm going to switch signs.

The negatives cancel out, which is equal to 9 over 7.

It only takes a few minutes to put on and for the signals to settle.

The signals that you are seeing here are action potential, are the same signals that the neurons of my brain, of our brain, use to exchange information.

And once again, the signs are different so it's a negative.

Well, once again, 16 divided by 8 is 2, but the signs are different.

Well, the minuses cancel out, so you get 3 plus 3

It can replace, or it can inhibit actually, signals.

Let's up the stakes a little bit, introduce some negative signs in here.

First you just look at each of the numbers as if there was no negative sign.

Well in this case, let's first of all look at the two numbers without signs.

So those negatives cancel out, and we're left with plus 15 7.

4 times 8 is 32 and the negatives cancel out, so that's positive 32 times 9.

Only different signs when multiplied get you a negative number.

Negatives cancel out, we could divide the numerator and the denominator by 10.

And what better way to do this than by interpreting the signals naturally produced by our brain, our center for control and experience.

Although we've gotten rid of the plus signs and the equals signs.

Consideration should be given to deleting some of these references as unnecessary.

So let's say 3 minus 3 well, these negatives cancel out, so that just equals 6

It's just like, oh, we just have to swap the signs and we would have gotten a negative 2.

You see how on the bottom two problems I had two different signs, positive 1 and negative 1?

And we'll talk more about what it means to receive and transmit a signal in this video and probably in the next few.

So we are really duplicating the kind of signals that you have on the optic nerve.

We actually see references to two cultures, both of which had ruled but had both fallen.

Then we take this guy where we switch signs. We have a minus. And we multiply him times the determinant of his submatrix, which is that right there.

Let's see if this changes signs around positive or negative 3.

And what better way to do this than by interpreting the signals naturally produced by our brain, our center for control and experience.

Well, you might say that the signs are different, but 0 is actually neither positive nor negative.

That is, how it takes information in from the outside world, and converts it into patterns of electrical activity, and then how it uses those patterns to allow you to do things to see, hear, to reach for an object.

Now just to orient you, each box is showing the firing patterns of several cells, and just as in the previous slides, each row is a different cell, and I just made the pulses a little bit smaller and thinner so I could show you a long stretch of data.

Those ticks and crosses represent the 7,800 houses we've looked at nationally around Australia, the same proportion.

The big brain integrates signals, which come from the running programs of the lower brain,

You could also say that as when the signs are different and you multiply the two numbers, you get a negative number.
