Spatiotemporal distortions of visual perception at the time of saccades.

19 Oct 2009 Both space and time are grossly distorted during saccades. Here we show that the two distortions are strongly linked, and that both could be a consequence of the transient remapping mechanisms that affect visual neurons perisaccadically. We measured ... Read more...

Driving under low-contrast visibility conditions in Parkinson disease.

4 Oct 2009 OBJECTIVE: To assess driving performance in Parkinson disease (PD) under low-contrast visibility conditions. METHODS: Licensed, active drivers with mild to moderate PD (n = 67, aged 66.2 +/- 9.0 years, median Hoehn-Yahr stage = 2) and controls (n = ... Read more...

Crystal structure of native RPE65, the retinoid isomerase of the visual cycle.

3 Oct 2009 Vertebrate vision is maintained by the retinoid (visual) cycle, a complex enzymatic pathway that operates in the retina to regenerate the visual chromophore, 11-cis-retinal. A key enzyme in this pathway is the microsomal membrane protein RPE65. This ... Read more...
