[Reactions of neurons of the disencephalon and midbrain of the salamander Salamandra salamandra to visual stimuli].
In 20 tectal and 33 diencephalic neurons, action potentials have been recorded in response to diffuse illumination and moving visual stimuli. In both visual centers, similar types of the neurons were found, i.e. directionally sensitive ones and those reacting to diffuse illumination, their receptive fields varying from 5 to 90 and more degrees. Some of the neurons were activated by stimulation of both ipsi- and contralateral eyes. Spontaneously active neurons were significantly more numerous in the tectum than in the diencephalon.
