In the fly visual system each optic ganglion (lamina, medulla, lobula, lobula plate) constitutes a retinotopically ordered set of neural columns in which each single column corresponds to one single optical axis in the visual field of the compound eye. This very precise mapping of the visual surrounding of the animal through the retinal input mosaic on to all four ganglia is one of the features which make the fly visual system extremely suitable for the systematic study of the basic principles and strategies which underlie the detection and processing of movement. In earlier work we proved the applicability of the well-known correlation model for the perception of movement in the description and prediction of the behavior of the wide-field movement detectors which integrate the activity of all neural columns at the level of the highest order ganglion, the lobula plate. Such a wide-field element as a natural continuation of our extracellular electrode is used, in a way, to study the temporal resolution properties of the highest order ganglion (without damaging any part of it) and to compare these properties with those at the level of the retina. It is shown that the temporal resolution at the level of the retina is an almost completely “stiff” one, whereas at the level of the lobula plate this processing is very flexible and that its time constants are tuned by the time course of the stimulus over a wide range. The consequences of this stimulus-dependent temporal behavior for the processing of images at various levels in this visual system are discussed against the background of adaptive modeling techniques. |
