Diencephalon: position & division (5parts) It lies between cerebrum & midbrain. The narrow space between the left & right diencephalons is the 3rd ventricle.
Dorsal thalamus is used as a center for judging the positions of the rest components of diencephalon.
The part anteroinferior to it is hypothalamus;the portion behind it is metathalamus; the anterio---posteriorly going & continuous structure superior to it is epithalamus,and the structure inferior to it (its base connecting midbrain) is subthalamus.

Internal Structure of ThalamusVentroposteriolateral nucleus(VPLN) is
to relay the superficial and deep sensation informations from neck, trunk & limbs to the superior 2/3 part of the
first sensory area(FSA) in crebrum.
Ventroposteriomedial nucleus(VPMN) is to transmit facial sensation informations (including
taste ) to the inferior 1/3part of FSASmell information is not sent to the center
through diencephophalon, but it is directly delivered to the gustatory area in cerebrum.
