Abstract

Experiments were performed which demonstrate that low power, pulsed microwave exposure induces a significant increase in local cerebral blood flow within the brain of the conscious rat. Previous studies purporting to examine changes in brain vascular permeability induced by microwave radiation must be re-evaluated in the light of these observed changes in blood flow.

Main findings

Low power, pulsed microwave exposure induced a significant increase in local cerebral blood flow in the brain of the conscious rat. The authors state that prior studies on microwave-induced changes in brain vascular permeability should be re-evaluated in light of the observed blood-flow changes.

Outcomes measured

local cerebral blood flow
brain vascular permeability (contextual/implicated)

Limitations

No exposure parameters reported in abstract (e.g., frequency, SAR, duration).
Sample size and experimental details not provided in abstract.
Animal study; generalizability to humans not addressed in abstract.
