Unlike other organs, the energy requirements of the brain are satisfied mainly due to aerobic glucose catabolism. The brain is practically not capable of synthesizing glucose from proteins and fats (gluconeogenesis). The passage of glucose through the

The high rate of energy metabolism of the brain is associated with intensive formation of macroergic compounds – ATP and creatine phosphate. The creatine phosphate – creatine system plays a role in stabilizing the level of

The hydrogen indicator of blood and, especially, the brain is maintained at a fairly stable level, and its changes significantly affect the activity of many enzyme systems. Despite the fact that the release of acidic metabolic

This barrier is a system that supports the selective flow of substances from the blood to the brain and vice versa, which creates conditions for the relative independence of metabolism in the brain. Anatomically, the BBB

The neurophysiological study of aging is closely related to the analysis of age-dependent characteristics. There are a huge number of physiological indicators, the age dynamics of which have been studied in elderly and old people. Obviously, the

In the transition from wakefulness to sleep, in parallel with the increase in slow-wave activity on the EEG, cerebral energy metabolism decreases. Local cerebral blood flow and oxygen consumption by the brain decrease during sleep by

It is well known that sensory stimulation increases the intensity of energy metabolism in the nerve centers involved in the transmission and processing of information rmatsii . During photostimulation, there is a two-wave increase in blood flow in

The learning process is accompanied by increased cerebral energy metabolism and local cerebral blood flow. N of data LMK measured in humans using SPECT, grew at a visually-motor learning. In the work of these authors, training was carried out

Energy metabolism and oxygen consumption are closely related. The higher the oxygen consumption, the more intense is the energy metabolism. It would seem that with increased ventilation of the lungs and, correspondingly, a greater supply of oxygen

And it is clear that hyperventilation starts a two-phase process: alkalosis in the free hand corresponds to the negative phase, after the end of hyperventilation, the potential difference is gradually restored. After removing the cuff and blood
