Abstract

In experiments on 22 rabbits the influence of a pulse microwave irradiation on extracellular activity of separate nervous cells of sensorimotori and occipital areas of a cortex brain is shown. The reaction could consist in activation or in braking frequency of the discharges, that was connected to frequency impulsation in an initial background. The researched mode of a microwave irradiation (1.5 GHz, duration of a pulsed-0.4 microsecond, frequency of their recurrence 1000 Hz, DFEpulsed-300 microW/sm2) had a corrigizing action.

Main findings

In 22 rabbits, pulsed microwave irradiation influenced extracellular activity of individual cortical nerve cells in sensorimotor and occipital areas. Responses included either increased or decreased discharge frequency, related to the initial background discharge pattern; the irradiation mode was described as having a "correcting" action.

Outcomes measured

Extracellular activity of individual nerve cells in sensorimotor and occipital cortex (discharge frequency changes: activation or braking)

Limitations

No sham/control condition described in the abstract
No quantitative results or statistical analysis reported in the abstract
Exposure metric reported as power density (DFEpulsed-300 microW/sm2) without SAR or absorbed dose
Short methodological details (e.g., blinding, randomization) not provided in the abstract
