"Real-time" obstacle avoidance in the absence of primary visual cortex.

31 Aug 2009 When we reach toward objects, we easily avoid potential obstacles located in the workspace. Previous studies suggest that obstacle avoidance relies on mechanisms in the dorsal visual stream in the posterior parietal cortex. One fundamental question ... Read more...

A comparison of treatment plans using linac-based intensity-modulated radiation therapy and helical tomotherapy for maxillary sinus carcinoma.

30 Jul 2009 This study evaluated whether helical tomotherapy (TOMO) planning could achieve better isodose distribution for the maxillary sinus while concomitantly sparing the adjacent _critical normal organs than linac-based step-and-shoot IMRT (s-IMRT) ... Read more...

Optical coherence tomography is less sensitive than visual evoked potentials in optic neuritis.

5 Jul 2009 OBJECTIVES: Determine the utility of optical coherence tomography (OCT) to detect clinical and subclinical remote optic neuritis (ON), its relationship to clinical characteristics of ON and visual function, and whether the retinal nerve fiber layer ... Read more...
