The interthalamic adhesion (also known as the massa intermedia, intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.
Localization of function of the thalamus can be illustrated through vascular thalamic amnesia. The damage to the tuberothalmic territory appears to have the most extensive effects in relation to this form of amnesia by affecting functions of arousal and orientation, learning and memory, personality, and executive function.

The loop involves connections between the cortex, the basal ganglia, the thalamus, and back to the cortex. It is of particular relevance to hyperkinetic and hypokinetic movement disorders , such as Parkinson's disease and Huntington's disease , [ 1 ] as well as to mental disorders of control, such as attention deficit hyperactivity disorder ...
Korsakoff syndrome stems from damage to the mammillary body, the mammillothalamic fasciculus or the thalamus. [ 68 ] [ 69 ] Fatal familial insomnia is a hereditary prion disease in which degeneration of the thalamus occurs, causing the patient to gradually lose their ability to sleep and progressing to a state of total insomnia , which ...
The spinothalamic tract is a nerve tract in the anterolateral system in the spinal cord. [1] This tract is an ascending sensory pathway to the thalamus.From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.
Thalamotomy is a complex procedure performed by specialist neurosurgeons. It is mostly indicated in cases of stroke, damage to third ventricle of brain, brain hemorrhage, accidents leading to head injury, oedema around thalamus, subdural hemorrhage, and cerebrovascular accident. There is also some evidence in thalamocortical dysrhythmia.
The cerebellothalamic tract or the tractus cerebellothalamicus, is part of the superior cerebellar peduncle.It originates in the cerebellar nuclei, crosses completely in the decussation of the superior cerebellar peduncle, bypasses the red nucleus, and terminates in posterior division of ventral lateral nucleus of thalamus.
However, the trigeminal lemniscus also carries pain and temperature sensations from the contralateral orofacial region, just as the spinothalamic tract carries these sensations from the contralateral body. Thus, the trigeminal lemniscus of the head is functionally analogous to both the DCML tracts and the spinothalamic tract of the body.
