title: [Distribution of direction-rate of movement neurons in frog optic tectum structures].
abstract: The neurons related to movement direction--velocity are equally distributed in the tectum opticum layers with representation in the latters of sensory, associative and effector structures which suggests equal participation of these structures in estimation of parameters of the visual stimulus movement. In the tectum opticum neurons, the inhibition restricting the excitation, seems to facilitate responses of separate groups of neurons related to analysis of direction--velocity parameters.
