Spatio-Temporal Quantification of Cerebral Blood Flow During Forepaw Stimulation of the Rat Using Laser Speckle Flowmetry

Not Accessible

Your library or personal account may give you access

Abstract

Laser speckle flowmetry was used to characterize activation flow coupling following forepaw/hindpaw stimulation. Different activation levels and duration were quantitatively investigated. The temporal response of the area of activation was independent of stimulus amplitude and distance from the activation centroid.
