what is the diencephalon located between?
the midbrain and hypothalamus
what is the central diencephalon?
the thalamus
what are the 3 parts of the diencephalon?
the thalamus
the prethalamus
the pretectum
where is the prethalamus in relation to the thalamus?
in front of the thalamus
where is the pretectal area in relation to the thalamus?
behind the thalamus
what does diencephalon mean?
‘interbrain’
what does the diencephalon link?
the main parts of the forebrain with the brainstem
what does prosomere 1 include?
the pretectal area
what does prosomere 2 include?
the thalamic area
what does prosomere 3 include?
the prethalamus
in development, in what direction is the hypothalamus in relation to the thalamus?
rostral
why is the thalamus dorsal to the hypothalamus?
because of the sharply bent neuraxis at the midbrain during development (the cephalic flexure)
what is the sharp flexure in the neuraxis at the midbrain known as?
the cephalic flexure
what sensory systems does the thalamus receive input from?
all but the olfactory system
where does the visual pathway terminate in the thalamus?
in the dorsal lateral geniculate nucleus (DLG)
where does the dorsal lateral geniculate nucleus end up projecting to?
the visual cortex
