[Relationship between the ability to extrapolate and the level of cerebral excitability].
In the experiments with self-stimulation of limbic brain structures on the rats of KM line an improvement in solving of extrapolation problems was observed. Self-stimulation of the limbic pathways is more effective than that of nuclear structures. It seems to be due to a more powerful afferentation caused by stimulation of the pathways that excites practically the whole visceral brain and the larger part of the neocortex. Increased excitability level of the central nervous system is an important condition for elementary reasoning activity; one of the criteria of such activity is the ability to extrapolate the direction of the movement of a meaningful stimulus.
