Features of brain energy metabolism

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

Change in cerebral energy metabolism and SCP in sensory stimulation

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 effect of hyperventilation on brain energy metabolism

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
