Weber's loop or Weber's loop (Wahler or Weiber) - on the outer wall of the optic canal of the spinal cord, starting from the optic thalamus and ending in the pons area opposite to the medullary bundle. In the space between the nerve fibers, small arteries are identified. On the right and left above the optic tracts there are connective tissue parts of the loop, protruding into the substance of both optic tracts. Weber's loop is classified as a structure of the reticular formation. Develops after 3 years of human life. In children there is a distinct pulsation of this loop. The pulsating expansion of Weber's artery in response to a mechanical rupture is accompanied by a gradual inhibition of affectively colored reactions. The expansion of the artery of the cerebral vessels indicates the general balance of a person. This reaction is aimed at normalizing autonomic balance and auditory perception. Normal development of nervous tissue occurs directly in the presence of a large amount of microelements in the blood vessels, such as iodine, copper, zinc, etc. Therefore, it is optimal for the body to receive zinc, iron, magnesium, phosphorus, cobalt, iodine, copper during the first two years of development nervous system (which is the age of the fetus while in the womb). Iron can be found in all healthy tissues of adults and children, and the walls of blood vessels contain the trace elements magnesium, calcium and phosphorus. Cyanocobalamin, a substance from the group of vitamins B12, eliminates scurvy and treats diseases of internal organs. Thanks to the properties of cobalamin, anemia is treated and prevented. This substance cleanses the blood and creates restoration processes during the destruction of hemoglobin.
