Diencephalic binocular wide field neurons in the frog


Single binocular neurons were recorded in the frog diencephalon (area dorsalis posterior and area ventralis thalami). These neurons respond to any moving stimulus from 1 ° 30 to 32 ° in diameter, without directional selectivity and to an ON-OFF light stimulation. They are not activated by stationary objects. Habituation is also commonly observed. The most important feature of these neurons is their wide receptive field which covers the whole visual field of the frog. Evidence that these neurons receive inputs from each tectum is discussed.
