This is an image that should provide an idea about what we mean by neurohacking.
Here what you see is an image, an axial image, through the brain.
It's an axial image.
If you don't quite follow every word that I'm saying right now, that's okay.
We'll say that throughout the course, exactly what every word means.
But this is an axial slice of a T1 image, and it represents
a subject who has an MS lesion that is identified in the middle of the brain.
And you also see a red box with
numbers associated on the right.
It may be interesting to look a little bit closer to the image to the left and
see how the left corner of the box is actually darker.
And as you progress from the left corner to the right corner of the image,
it becomes lighter, and then it becomes darker again.
If you look in the right side of the box, you see that the numbers themselves,
which correspond to the actual image that you see on the left do the same thing.
You start in the left corner from 120, 130.
Then as you progress through the image towards the right corner,
numbers becomes larger first.
In the range of 200 you see some 202 some 200, 192, and it may become smaller again.
They get in the range of 160, not as small as they were in the left corner, but
quite much smaller than actually they are in the middle of the image.
We will see much later that this is actually an image
where you see a contrast enhancement identifying the brain
blood barrier penetration by gadolinium chelates.
As I said, there are a lot words that don't make a lot of sense right now, but
we will make our way through that as we go along.
