Temperature entrainment of Drosophila's circadian clock involves the gene nocte and signaling from peripheral sensory tissues to the brain.

27 Oct 2009 Circadian clocks are synchronized by the natural day/night and temperature cycles. Our previous work demonstrated that synchronization by temperature is a tissue autonomous process, similar to synchronization by light. We show here that this is ... Read more...

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...
