Midbrain sulcus Lateral

Midbrain sulcus Lateral (lat. sulcus lateralis mesencephali) is a groove that runs along the surface of the midbrain in the lateral (side) part of the cerebral hemispheres. It is one of the largest and most important fissures in the brain, as it separates the white and gray matter of the midbrain and provides communication between its different parts.

The midbrain fissure is located on the lateral side of the cerebral hemispheres, starting at the top of the frontal lobe and continuing to the posterior part of the temporal lobe. It is about 4-5 centimeters long and about 1.5-2 millimeters wide. The groove passes through such important structures as the thalamus, hypothalamus, globus pallidus, red nucleus and others.

One of the main functions of the midbrain sulci is to provide communication between different parts of the brain and ensure coordination of movements. For example, the midbrain sulcus is involved in the regulation of muscle tone, eye movement, hearing, smell and other functions.

In addition, the midbrain fissure plays an important role in learning and memory, as well as in the regulation of emotions and mood. It may also be associated with certain mental disorders such as schizophrenia and depression.

Overall, the midbrain fissure is an important structure in the brain and plays a key role in many body functions.

The lateral sulcus of the midbrain (sulcus lateralis mesencephali) is a deep groove that runs through the midbrain on the right and left sides. It is part of the transverse brain and connects the anterior and posterior parts of the midbrain.

The lateral mesencephalon groove is about 10 mm long and 3-4 mm wide. It starts from the anterior surface of the cerebellum and runs along the midline to the posterior surface of the thalamus. Along its path, the sulcus passes through various structures, including the optic tract, internal capsule, anterior part of the internal capsule, optic colliculus, and medial thalamus.

The function of the lateral midbrain groove is to connect various brain structures to each other. For example, the lateral mesencephalon fissure provides communication between the thalamus and the optic tract, as well as between the thalamus and the cerebral cortex. This allows information about visual stimuli to be transmitted to and from the cerebral cortex.

In addition, the lateral mesencephalon fissure is involved in the regulation of body balance and coordination of movements. It also plays an important role in processing information related to emotions, including fear, anger and joy.

Thus, the Lateral mesencephalon sulcus is an important element of the brain structure, which plays an important role in the transmission and processing of information. Its violations can lead to various diseases and pathologies, such as visual impairment, motor coordination and emotional disorders.
