| Abstract: | The possible mechanisms of visual information coding in the frog optic tectum were studied by extracellular recording of unit activity. It was postulated that information is coded spatially and that its precision is increased by the use of various types of time codes, making wide use in particular of differences in response latencies. These differences are also important on their own account, and they act as a component of the time codes (latency-frequency, latency-structural, and so on). The uniform distribution of neurons processing visual information and, in particular, analyzing the different parameters of visual signals (direction-velocity, lightness-darkness, and so on), among the structures of the tectum is evidence that the mechanism of analysis of the parameters of visual stimulus movement is distributive in type.Research Institute of Neurocybernetics, State University, Rostov-on-Don.
