00:00:00.730 --> 00:00:05.730
(light upbeat music)

00:00:17.000 --> 00:00:20.000
- David: The Human Connectome Project aims to give us the best

00:00:20.000 --> 00:00:24.570
available understanding and information

00:00:24.570 --> 00:00:28.970
about the structure, function, and connectivity

00:00:28.970 --> 00:00:31.070
of healthy adult brains.

00:00:31.330 --> 00:00:32.730
On the right you see

00:00:32.730 --> 00:00:37.670
an image, a view of one slice through the brain

00:00:37.670 --> 00:00:41.100
using the method that we all structural magnetic resonance

00:00:41.100 --> 00:00:43.330
imaging or structural MRI.

00:00:43.330 --> 00:00:45.730
We can view other slices by scrolling

00:00:45.730 --> 00:00:49.970
forwards through the brain to get different views.

00:00:49.970 --> 00:00:54.570
You can see that the outside of the brain

00:00:54.570 --> 00:00:58.230
is dominated by the complex folds of the cerebral cortex.

00:00:58.230 --> 00:01:00.670
These folds or convolutions are

00:01:00.670 --> 00:01:04.200
what give us a large amount of cortical surface

00:01:04.200 --> 00:01:07.370
area to process information, but to understand them

00:01:07.370 --> 00:01:09.770
what's going on, we need to

00:01:09.770 --> 00:01:12.170
look at the structure of

00:01:12.170 --> 00:01:15.270
the cerebral cortex more closely,

00:01:15.270 --> 00:01:17.200
and we can capture that structure

00:01:17.200 --> 00:01:21.370
by using mathematical computational

00:01:21.370 --> 00:01:23.630
methods to extract the

00:01:23.630 --> 00:01:25.600
shape of the cortex,

00:01:25.600 --> 00:01:29.170
these folds are now captured by green and blue

00:01:29.170 --> 00:01:33.800
contours that run along the margins of the grey matter.

00:01:33.800 --> 00:01:36.330
Using that information we can make three dimensional

00:01:36.330 --> 00:01:41.230
geometric models as seen on the left side over here

00:01:41.230 --> 00:01:45.300
of the left hemisphere and right hemisphere.

00:01:45.300 --> 00:01:49.130
From the lateral or side views and from the midline

00:01:49.130 --> 00:01:50.900
or medial views.
