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 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.
[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.

Hypertension, atrial fibrillation and smoking pose a stronger risk for severe stroke, according to a new study. However, lifestyle changes can help prevent stroke.
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.
Signs of cooling inflation paved the way for September’s first rate cut in four years, with economic data indicating a continued decline from a peak of 9.1% in June 2022 to rates that have ...
