You can get tired not only at the machine at the factory, but also at the keyboard and monitor in the office. Biologists have found
It turned out that in the active cortexThe brain accumulates intermediate metabolic products, which lead to fatigue. Fatigue signals to us that we should stop this activity in order to preserve the working capacity of the brain.
Scientists have conducted experiments in whichhad to solve cognitive tasks all day long. The first group solved easy problems, and the second - difficult ones. In volunteers, the brain was monitored using NMR spectroscopy.
Over time, participants from the second group startedshow signs of fatigue, and glutamic acid accumulated in the lateral areas of the prefrontal cortex of their brains. This complicates the work of synapses: there is little glutamate inside the neurons, and too much outside. So it becomes toxic to nerve cells.
