Emotional state in seniors with different values of local SCP in the frontal and occipital regions . The ordinate axis – the value of the UPP. F # and O # – local SCP in the frontal and occipital regions
At low values of local SCP in the occipital region –5.1 + 1.2 mV, not only normal affect is observed, but also good indicators of long-term memory .
Thus, the growth of averaged SCP and SCP in a number of areas of the brain during aging is accompanied by adverse changes in memory, mental activity, and also an emotional state. Some psychological characteristics are optimal with an average or even low level of constant potentials. With an increase in SCP, reflecting the accumulation of [H + ] in the brain, free-radical oxidation increases. This process damages nerve cells, which adversely affects brain activity .
With aging, as a result of a decrease in the activity of antioxidant systems, the accumulation of redox-active iron in cells, damage to mitochondria, and deterioration of cerebral blood flow, the effectiveness of antistress protection decreases. Therefore, even a slight acidification of the brain and, accordingly, an increase in SCP significantly worsens its performance.
Conclusion
Energy metabolism of the brain, as well as its relationship with psycho-physiological characteristics change at different stages of age development and aging. In childhood, the overall level of energy metabolism in the brain is an important factor for successful learning. With a lack of energy exchange, reflected in a low average SCP, performance decreases. This dependence is determined by the need for energy supply of cerebral plastic processes, in particular, activation of synaptic contacts between neurons. Energy processes should also provide a sufficient level of brain activation necessary to maintain concentrated attention during training.
