[Visual information coding in the frog midbrain tectum].
Possible mechanisms of optic information encoding in the frog tectum are considered on the basis of the extracellular recording of the tectum neuron impulse activity. It is suggested that optic information is coded in the frog tectum by means of space coding and is made more precise with the help of different types of time-coding, the coding by latency difference being used more widely. This mechanism may function either independently or be a component of complex time-codings. A uniform distribution in the tectal structures of neurons processing optic information indicates that the mechanism of exact analysis of optic stimulus movement parameters should be a distribution function of the same structures.
