Study Summary
This study in, healthy human subjects using fMRI and MRS (magnetic resonance spectroscopy) characterizes, how attention and acetylcholine affect visual perception and the brain's representation of the visual environment. Levels of acetylcholine in the cerebral cortex will be enhanced by administration of donepezil, an inhibitor of acetylcholinesterase. Half the subjects will receive donepezil and other half will receive placebo.
Primary Outcome
