However, during natural viewing where saccades and fixational eye movements change the stimulus situation at all points of the retina at least every 200 300 ms [18], [37], the attenuation effect observed here is likely to cause some aspects of a natural image to go unperceived.
These QSAR models are based on a solid framework of knowledge about the mechanisms that cause particular aspects of toxicity and are therefore likely to be highly predictive.
