Abstract

A television version of the densitometric method of Eke (1981) for imaging cerebrocortical1 microflow2 has revealed a distinctly different distribution of cerebrocortical microflow in groups of normo- and spontaneously hypertensive rats (NPR, SHR respectively) in control condition, when the distribution of microf lows within one map’s area was normalized by the map’s mean and averaged for each group. These, so called, fractionation histograms of microflow showed a partial decrease of the intraparenchymal vascular resistance in the SHR group as likely being a secondary response to an excessively increased extraparenchymal resistance.
