the thalamus.
the hypothalamus.
the subthalamus.
the epithalamus.
The third ventricle lies between the halves of
the diencephalon.


It is a large ovoid mass of grey matter that
forms major part of diencephalon.
It is a station for all main sensory systems.
Its anterior end forms the posterior boundary
of interventricular foramen.
Its posterior end forms pulvinar.
Its medial surface forms the lateral wall of the
third ventricle.


Its lateral surface separated from lentiform
nucleus by internal capsule.
It is sub-divided into anterior, medial and
lateral parts, in each we have a group of
thalamic nuclei.

relaying sensation, spatial sense and motor
signals to the cerebral cortex, along with the
regulation of consciousness, sleep and
alertness.




Lies inferior to thalamus.
Its structure is extremely complex.
It has subthalamic nucleus which has
connection with corpus striatum.
Subthalamus also contains many important
tracts.



Consists of habenular and the pineal gland.
Habenular nucleus is the center for integration
of olfactory , visceral and somatic pathways
Pineal glands



It extends from the region of optic chiasma to
the mammillary bodies
lies below the hypothalamic sulcus, on the
lateral wall of third ventricle.
There is hardly any activity in the body that is
not influenced by the hypothalamus.
