[Amplitude-temporal characteristics of evoked responses of the visual analyzer to stimuli of growing intensity].
A study was made on cats of the dependence of latency, peak latency, amplitudes and slopes of I and II phases of primary evoked potentials in the chiasm, the colliculi, the lateral geniculate body and visual cortex on the intensity of the photic stimulus in the range of intensities of II orders above the threshold. Practically in the whole examined range, the logarithmic connection is retained, testifying to the extremely wide possibility of the visual system to discriminate a signal in securing a reflex act.
