2. Midbrain tegmentum - Wikipedia

   en.wikipedia.org/wiki/Midbrain_tegmentum

   Unlike the midbrain tectum (which is a sensory structure located posteriorly), the midbrain tegmentum, which locates anteriorly, is related to a number of motor functions. Within the tegmentum, the red nucleus is in charge of motor coordination (specifically for limb movements) and the periaqueductal gray matter (PAG) contains critical circuits ...

3. Tegmentum - Wikipedia

   en.wikipedia.org/wiki/Tegmentum

   The midbrain tegmentum is the part of the midbrain extending from the substantia nigra to the cerebral aqueduct in a horizontal section of the midbrain. Structures included in the midbrain tegmentum include the red nucleus, reticular formation, and substantia nigra. The red nucleus is responsible for controlling basic body and limb movements.

4. Midbrain - Wikipedia

   en.wikipedia.org/wiki/Midbrain

   The midbrain tegmentum is the portion of the midbrain ventral to the cerebral aqueduct, and is much larger in size than the tectum. It communicates with the cerebellum by the superior cerebellar peduncles , which enter at the caudal end, medially, on the ventral side; the cerebellar peduncles are distinctive at the level of the inferior ...

5. Dopaminergic cell groups - Wikipedia

   en.wikipedia.org/wiki/Dopaminergic_cell_groups

   Group A10 is the largest group of dopaminergic cells in the ventral midbrain tegmentum of rodents [6] and primates. [4] The cells are located for the most part in the ventral tegmental area, the linear nucleus and, in primates, the part of central gray of the midbrain located between the left and right oculomotor nuclear complexes.

6. Medial longitudinal fasciculus - Wikipedia

   en.wikipedia.org/wiki/Medial_longitudinal_fasciculus

   The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal, responsible for oculomotor control, head posture, and vertical eye movement. [2]

7. Ventral tegmental area - Wikipedia

   en.wikipedia.org/wiki/Ventral_tegmental_area

   Neurobiologists have often had great difficulty distinguishing the VTA in humans and other primate brains from the substantia nigra (SN) and surrounding nuclei. Originally, the ventral tegmental area was designated as a ‘nucleus’, but over time ‘area’ became the more appropriate term used because of the heterogeneous cytoarchitectonic features of the region and the lack of clear ...
