[7] [8] [9] Nuclei within the MLR receive inputs from the substantia nigra of the basal ganglia and neural centers within the limbic system. [10] Projections from the MLR descend via the medullary and pontine reticulospinal tracts to act on spinal motor neurons supplying the trunk and proximal limb flexors and extensors.
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.
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.

The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1]
The 2024 Rockefeller Center Christmas tree has sentimental roots.. The tree was planted by the Albert family back in 1967 in West Stockbridge, Massachusetts, when Earl Albert and his late wife ...
Jamal Murray tops the list of guards to avoid at their current cost in 2024-25 fantasy basketball leagues amid concerns about his health ahead of the season.
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
