Subcutaneous commissure Posterior

The Subtubercular Commissure Posterior is an anatomical structure that connects the posterior part of the thalamus to the subtubercular nucleus. It is also known as the Trout commissure, named after the German neurologist and physiologist Karl Forel.

The Subtubercular Posterior commissure is one of the most important structures in the thalamic system. It plays an important role in transmitting information between the thalamus and other parts of the brain. The thalamus is an important processing center for sensory information received from the senses and transmits this information to the cerebral cortex. The subcutaneous posterior commissure plays a key role in the implementation of this transfer.

In the thalamus, information from the senses is processed and transmitted to other areas of the brain through this commissure. In addition, the subcutaneous posterior commissure also plays a role in regulating the level of wakefulness, sleep and other states of consciousness.

How exactly the Subcutaneous Posterior commissure works is not fully understood. However, it is known to be associated with various diseases such as Parkinson's disease, epilepsy and other neurological disorders. In addition, studying this structure may help in the development of new treatments for these diseases.

Thus, the subcutaneous posterior commissure is an important anatomical element of the thalamic system, which plays a key role in processing sensory information and regulating various states of the body.

The subthalamic commissure is a combination of two areas of the brain: the posterior nucleus (subthalamicum) and the lateral piriformis lobe, through which the thalamus, which is the center of the visual cortex, passes. The posterior part of the thalamus connects to the subthalamus through the posterior commissure.

The neurons of the posterior nuclei of the thalamus contain glutamate. They are also involved in the transmission of inhibitory signals through the corpus callosum, and the posterior commissure enters the ischiothalamic and corticospinal tracts, making them at the center of epileptic patterns.

The lateral piriformis lobe is involved in the formation of the functional localization of the limbs - this is the ratio of the neuronal activity of the anterior parts of the brain for making movements of one or another limb. The lateral lobes of the piriformis nucleus are important for the functioning of the human kinesthetic system, which is responsible for the accuracy of muscle control, muscle coordination and body orientation in space.

The anterior commissure is normally invisible, but it can be easily noticed after drinking alcohol or with decreased circulatory tone. In such cases, adhesions become more visible on x-rays, which is why specialists can determine alcohol-induced brain damage. Adhesions are formed as a result of the impact of a tumor or cyst, which has led to deformation of the surrounding tissues.

The hypothalamic commissure stimulates the memory of short stimuli and also facilitates the emergence of traces of recent short-term experiences. Such memories are difficult to evaluate due to their very short duration, and therefore they need to be polished by new experiences so that they become more accessible to perception. If the vestibular and coordination apparatuses are damaged, the commissures of the hypothalamus may slow down or completely stop transmitting information about the movements of the head and body. This mechanism is probably associated with a very high rate of information exchange between the structures of the central nervous system.
