[Separation of certain local stimuli on a nerve net]

Possibility for discerning a local stimulus (monochromatic colour, pure tone, injection etc), and the evaluation of the stimulus closeness to the local one on the neuron net were shown earlier. The present work solves the problem of discerning the signal composed of several local stimuli, which allows to approximate the initial signal by the sum Gaussian. The results explain possible evaluation of overtones of the sound signal and similar psychophysical effects. A model is described of "tuning" the receptor to one of several simultaneously acting signals produced by different sources. The structure of the neuron nets which realize the problems under analysis is discussed.
