Evolutionary replacement of UV vision by violet vision in fish.

26 Sep 2009 The vertebrate ancestor possessed ultraviolet (UV) vision and many species have retained it during evolution. Many other species switched to violet vision and, then again, some avian species switched back to UV vision. These UV and violet vision are ... Read more...

Mislocalization of flashed and stationary visual stimuli after adaptation of reactive and scanning saccades.

31 Aug 2009 When we look around and register the location of visual objects, our oculomotor system continuously prepares targets for saccadic eye movements. The preparation of saccade targets may be directly involved in the perception of object location because ... Read more...

Responses to static visual images in macaque lateral geniculate nucleus: implications for adaptation, negative afterimages, and visual fading.

13 Jul 2009 Adaptation to static scenes is a familiar and fundamental aspect of visual perception that causes negative afterimages, fading, and many other visual illusions. To establish a foundation for understanding the neuronal bases of such phenomena and to ... Read more...
