Enhancement of cerebral blood flow and cognitive performance following pharmacological blood pressure elevation in chronic hypotension.

abstract：:Categorization is a basic means of organizing the world around us and offers a simple way to process the mass of stimuli one perceives every day. The ability to categorize appears early in infancy, and has important ramifications for the acquisition of other cognitive capacities, but little is known of its development...
