Percentage Distribution (Mean±SEM) of Low Capillary (CAP; <1 mm/sec) and High Thoroughfare Channel (TFC; >1 mm/sec) Flow Velocities in the Cerebral Cortex of Rats

		ICP group (%) n=10			MAP group (%) n=10
CPP (mm Hg)	MAP (mm Hg)	<1 mm/sec (CAP)	>1 mm/sec (TFC)	MAP (mm Hg)	<1 mm/sec (CAP)	>1 mm/sec (TFC)	p <

p Values refer to CAP and TFC percentage comparisons of the entire distribution between the ICP and MAP groups at each CPP.

ICP, intracranial pressure; MAP, mean arterial pressure; CPP, cerebral perfusion pressure.
