I want to give you another tool to localize
0:02
the intraparietal sulcus.
0:05
First, I'd like to draw it in the sagittal projection.
0:10
And then I'll show you this sign that you can use.
0:13
So, here it is as an arcuate shaped structure.
0:15
Remember, you don't see the whole thing
0:18
because it's so convoluted
0:19
and involuted from the surface of the brain.
0:21
It's very deep.
0:23
But if I were to show you exactly where
0:25
that spot was by cross-referencing it,
0:27
it corresponds right to this locus right here.
0:31
Now, we see part of it on this one cut.
0:34
And if I was to take the brain, as we did before,
0:38
and divide it up into 12 o'clock and 6 o'clock,
0:45
then we have at the widest biparietal diameter,
0:48
we've got 9 o'clock and 3 o'clock,
0:51
something like that.
0:53
And then we're going to take this sulcus,
0:54
which goes from 3 o'clock,
0:56
and it usually lands somewhere around here
0:58
at around 5 o'clock.
1:00
And then on the other side,
1:01
this would be 7 o'clock.
1:02
We can actually see it here at 7 o'clock.
1:05
Now, 75% of the time on the left side,
1:08
this intraparietal arcuate-shaped sulcus is continuous.
1:11
In this case, it's a little bit broken in the back.
1:14
On the right side, it's a little more disorganized,
1:17
so it's hard to pick it out from the
1:18
9 o'clock to the 6 o'clock position.
1:20
So, it's a little easier on the left and then you
1:22
extrapolate on the right just to make it work,
1:25
So if I take these lines away, you can see it now.
1:27
There it is right there,
1:29
going from 3 o'clock to approximately 5 o'clock,
1:33
maybe a little bit past 5 o'clock,
1:35
in the posterior aspect of the left parietal region
1:39
of the brain. The intraparietal sulcus,
1:41
the clock face sign for identifying it as the divider
1:45
of the superior and inferior parietal lobule.
