The central tegmental tract (tractus centralis tegmentalis, tractus thalamolivaris) is a bundle of nerve fibers that connects the thalamus and limbic system with the cerebellum and cerebral cortex. This pathway is one of the most important pathways in the central nervous system, as it provides communication between the thalamus and other brain structures.
The tegmental tract Central is one of three major pathways connecting the thalamus to other structures, including the cerebellum, cerebral cortex, and hypothalamus. It consists of two parts: the first section is called the central tegmental bundle of Bechter, and the second is the thalamulolivarian tract.
Bechter's central fasciculus tegmentum originates in the thalamus and passes through the posterior limb of the internal capsule, where it crosses the internal capsule and continues on to the cerebellum. During its journey through the cerebellum, it provides connections to various cerebellar structures such as the dentate nucleus and the dentate conus nucleus.
The thalamulolivarian tract begins in the thalamus, passes through the middle limb of the internal capsule and continues in the limbic system. It connects the thalamus to the hypothalamus and limbic nuclei, providing communication between these structures and regulating various functions such as homeostasis and emotional response.
The functions of the central tegmental pathway include regulation of emotion levels, organization of behavior, control of sleep and wakefulness, and regulation of homeostasis. Dysfunction of the tegmental tract can lead to various neurological diseases such as Parkinson's disease, depression, attention deficit hyperactivity disorder (ADHD), and other behavioral and mood disorders.
Thus, the central tegmental pathway plays an important role in the regulation of various brain functions and is a key element in the functioning of the central nervous system.
