[Scott] OK, what we've got here is a coronal section of the brain, and we’re going to
do our best to label it so we’ll start of by just labelling some of the lobes. We can
see here that the view is quite posterior, so we have to bear in mind parts of the cortex
that we’re going to see at this level here. So around this section here, this is going
to be the Temporal Lobe. And this section round here is going to be the Parietal Lobe. OK,
so we have a Temporal Lobe this side and this side, a Parietal Lobe here and a Parietal
Lobe there. We have the Longitudinal Fissure in the mid-line just here. We have the body
of the Lateral Ventricle in here. This structure in green is the Corpus Callosum. And the structure
in red on each side here is part of the body of the Fornix, this is the major outflow from
the hippocampus and part of the Papez Circuit: so body of Fornix there. We’re going to
clear these diagrams now so we can start again and label some other structures. So we've
also got the Thalamus in here. We have these stained areas in here of course: the Substantia
Nigra. In here in each Temporal Lobe the small section of coiled brain there is the Hippocampus.
And in here we have part of the middle Cerebellar Peduncle which is of course in the Pons. Here
we have the Medulla and it’s worth pointing out we’ve got an in-folding region of cortex
on each side and that’s known as the Insula, like that. Let’s then create some more room
for ourselves and have a look at some of the other structures. We've got a couple of structures
in here: this is the head of the Caudate Nucleus- part of the Basal Ganglia. We also have the
Red Nuclei in here like this-this is the Red Nucleus which is part of the Midbrain. We
have the posterior limb of the Internal Capsule which is running down here on each side. So
that is the posterior limb of the Internal Capsule (I.C. for Internal Capsule) and in
continuation with that we have part of the Midbrain called the Cerebral Crus or Crus.
So that’s part of the Midbrain as well, Corticospinal Tract fibres will run anteriorly
through there. It’s probably also worth pointing out that this space just in here
is the inferior horn of the Lateral Ventricle. And…and on top of that we have one last
structure to name, I'm going to use blue for this: we have part of the Basal Ganglia- I'm
not going to use blue for this that’s a silly idea, because that’s too close to
the Cerebral Crus. So I'm going to use this yellow colour just to highlight another part
of the Basal Ganglia in here called the Putamen. OK, that’s it!
