The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. Also located in the diencephalon, are the epithalamus and the perithalamus which contain regions called the zona incerta and the reticulate nucleus.
The thalamus lies at the top of the brain stem near the centre of the brain from where nerve fibres project out towards the cerebral cortex.


The thalamus is supplied with blood by four branches of the posterior cerebral artery, namely the polar artery, paramedian thalamic-subthalamic arteries, thalamogeniculate arteries and the posterior choroidal arteries. Within the thalamus lie myelinated nerve fibres called lamellae that separate the structure into individual parts.

The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex.
The thalamus is divided into two prominent bulb shaped masses of around 5.7 cm in length and positioned symmetrically on each side of the third ventricle. Distinct groups of neurons make up other parts such as the periventricular, the nucleus limitans and the intralaminar elements, which are collectively called the allothalamus.


It is a subdivision of part of the brain called the diencephalon and is one of the largest structures derived from the diencephalon during embryonic development.
The allothalamus differs in structure form the major part of the thalamus called the isothalamus.
