title: [The meaning of the Weber-Fechner Law IV. The psychometric curve, the interaction between inter hemisphere and the interaction in intrahemisphere].
abstract: The subject was presented with a pair of lines. One line was an objective referent line Ro and did not change its length. The other was a test line and changed the its length. The observer must report--where the longer line was--above or below in the pair. On the basis neurophysiological, psychophysical data and new type of the psychometrical curve a complex neuronal construction was built. The comparison of action of the neuronal construction with the psychophysical data on different stages of introduction the visual information showed that in both cases at first stages of introduction the information referent subjective stimulus Rs is not equal to Ro. But at the last stages, when Weber's fraction is obtained Rs = Ro. This result allows to suggest that the suggested neuronal contraction is near to the real constriction of the visual brain.
