2. Thalamus - Wikipedia

   en.wikipedia.org/wiki/Thalamus

   The thalamus is a paired structure of gray matter about four centimetres long, located in the forebrain which is superior to the midbrain, near the center of the brain with nerve fibers projecting out to the cerebral cortex in all directions.

3. Midbrain - Wikipedia

   en.wikipedia.org/wiki/Midbrain

   The midbrain or mesencephalon is the uppermost portion of the brainstem connecting the diencephalon and cerebrum with the pons. [2] It consists of the cerebral peduncles , tegmentum , and tectum . It is functionally associated with vision, hearing, motor control, sleep and wakefulness, arousal ( alertness ), and temperature regulation.

5. Artery of Percheron - Wikipedia

   en.wikipedia.org/wiki/Artery_of_Percheron

   The functions of the thalamus and midbrain include the regulation of consciousness, sleep and alertness. Occlusion of the artery of Percheron, for example by a clot, could result in a posterior circulation infarct impairing structures on both sides of the brain. This can produce a bizarre disturbance such as sleep from which the patient cannot ...

6. Cerebral arteries - Wikipedia

   en.wikipedia.org/wiki/Cerebral_arteries

   Posterior cerebral artery (PCA), which supplies blood to the posterior portion of the brain, including the occipital lobe, thalamus, and midbrain [5] Both the ACA and MCA originate from the cerebral portion of internal carotid artery , while PCA branches from the intersection of the posterior communicating artery and the anterior portion of the ...

7. Brainstem - Wikipedia

   en.wikipedia.org/wiki/Brainstem

   In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1] The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the diencephalon is included in the brainstem. [2] The brainstem is very small, making up around only 2.6 percent of the brain's total ...

8. Midline nuclear group - Wikipedia

   en.wikipedia.org/wiki/Midline_nuclear_group

   The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus; paratenial nucleus (nucleus parataenialis) nucleus reuniens (also known as the ...

9. Medial lemniscus - Wikipedia

   en.wikipedia.org/wiki/Medial_lemniscus

   The medial lemniscus carries axons from most of the body and terminates by synapsing with third-order neurons in the ventral posterolateral nucleus of the thalamus. [3] at the level of the mamillary bodies. Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the ...
