We have been studying peculiarities of vegetative provision of mental activity with different level of difficulty. It was revealed that efficiency of mental activity of children from junior school depends on the difficulty of the given visual information and vegetative provision. It was proved that children from junior school had the highest level of mental activity with easiest tasks, but vegetative provision was minimal. When the task became more difficult earning capacity of the brain was down but we saw more expressed change in vegetative provision. In case of the highest level of visual information presentations we saw the lowest level capability of the brain but reducing of vegetative provision. We discussed mechanisms of the links between working ability of the brain and vegetative provision of mental activity of different difficulty level.
我们一直在研究不同难度水平下精神活动的营养供应特点。结果显示，小学生精神活动的效率取决于给定视觉信息的难度和营养供应。事实证明，小学生在面对最简单任务时精神活动水平最高，但营养供应最少。当任务变得更困难时，大脑的工作能力下降，但我们看到营养供应方面有更明显的变化。在视觉信息呈现水平最高的情况下，我们看到大脑的能力水平最低，但营养供应减少。我们讨论了大脑工作能力与不同难度水平精神活动的营养供应之间联系的机制。
