Disruption of functional connectivity in clinically normal older adults harboring amyloid burden.

5 Oct 2009 Amyloid deposition is present in 20-50% of nondemented older adults yet the functional consequences remain unclear. The current study found that amyloid accumulation is correlated with functional disruption of the default network as measured by ... Read more...

The electrocortical effects of enflurane: experiment and theory.

29 Sep 2009 BACKGROUND: High concentrations of enflurane will induce a characteristic electroencephalogram pattern consisting of periods of suppression alternating with large short paroxysmal epileptiform discharges (PEDs). In this study, we compared a ... Read more...

"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...
