Here's what is asserted:
'Gray matter of diencephalon'
:SLOTS (('constitutional part of' 'Diencephalon')
('constitutional part' 'Neuronal component of gray matter of diencephalon')
('regional part of' 'Gray matter of forebrain')
('constitutional part of' 'Neural tissue of diencephalon')
(FMA::FMAID "83912") ('dimension' "3-dimension")
('Preferred name' 'live_incus_fm_12252'))
:SUBCLASSES ('Gray matter of subthalamus'
'Gray matter of epithalamus'
'Gray matter of thalamus'
'Gray matter of hypothalamus')
:IS-A ('Gray matter of neuraxis')
We have the same question as with Thalamus. There are several
subclasses, each of which would be an instance of Gray matter of
diencephalon, if that's the intended meaning.
Each would have a constitutional part 'Neuronal component of gray matter of diencephalon', which I expect is unintended.
What I think might be meant is that the Gray matter of xxx classes are
*part* of the Gray matter of the diencephalon.
Is that the case?
I think I see this pattern in a number of places.
Separately, note that there are many cases where Gray matter of xxx and White matter of xxx are not asserted part of xxx. I believe that they should be asserted constitutional part of xxx, yes?
