Frenum of the anterior medullary velum

Cerebral frenulum

**Forebrain frenulum** is the connection between the frontal lobe and the midline of the brain. It plays an important role in the regulation of motor and emotional functions, and is also the location of many higher mental centers that regulate our thoughts, feelings and behavior. Therefore, disturbances in this area can lead to various psychological and physical disorders. In this article we will look at the structural features, functions and diseases associated with the forebrain frenulum.

*Why is it needed*

The frenulum is an approximately 7 mm thick plate of gray matter that connects the anterior and middle thirds of the frontal lobes in monkeys and other mammals. In humans, it has a more complex structure and function. In a section through the frontal gyri and diencephalon, it usually appears as a light spot surrounded by a darker mass of brain tissue.

The main importance of the forebrain frenulum is that it maintains communication between the frontal lobes and other parts of the brain, especially between the temporal lobe and the pons. It coordinates movements and mental activity, controls emotional reactions, takes part in the processes of learning and memorizing information, and regulates the processes of sleep and wakefulness.

Typically, this region is relatively underdeveloped in adults, as it is only necessary for the achievement of certain cognitive and behavioral structures during development. However, if disturbances occur, a variety of symptoms may occur, including decreased attention, memory, language comprehension, weakened willpower, apathetic or irritable mood, aggression, behavioral and communication problems, poor concentration, and cognitive dysfunction.

Upper cerebral frenulum - where is it located?

The frenulum refers to the connection of the upper two lobes of the cerebral hemispheres with each other. They are characterized by their large size and are also attached to the medulla oblongata. It was once thought that such connecting bridges were found only in the brains of primates. Today we know that all mammals and humans have them. *Function*

Embryonic brain tissue at the junction of the developing paired anterior lobes takes an active part in the formation of the forebrain frenulum. After birth, a slight bend in the area of ​​the frontal brain, located at the junction of both lobes, can be noted.
