Perceptual adaptation: motion parallels orientation

Adaptation phenomena provide striking examples of perceptual plasticity and offer valuable insight into the mechanisms of visual coding. Within the context of recent progress in neurobiology and computational modelling, I review evidence from studies employing psychophysical adaptation to investigate orientation and motion processing. These studies reveal marked similarities between the orientation and motion domains, raising the possibility that common computational principles underlie the processing of orientation and motion despite apparently distinct cortical substrates.
