title: [A neuronal network simulating the simultaneous contrast of equiluminous colors].
abstract: The vector model is advanced of simultaneous contrast of equiluminous colours. The basic characteristics of simultaneous colour contrast are related to test field-induction field interaction. The colour contrast depends on activity of the neurons which subtract the excitations arising in analogous neurons in the test and induction fields. Signals from the subtracting neurons come to the summing neurons via the local inputs and are summed by these neurons. The selective colour detectors are supplied with inputs from these summing neurons. In case when the induction and test fields are of the same colour and their excitation vectors coincide, the test field colour depends on the neurons which are excited only by the test field; the induction filed does not contribute to test field colour. If the test and inductions fields differ in hue or saturation the induction field colour acts in such a way that excitation vector of the test field deviates from that of the induction field. The presented network can be used to simulate neurophysiological and psychophysiological experiments.
