Researchers applied microwave irradiation sacrifice to rats and measured brain temperature, enzyme inactivation rates, and levels of acetylcholine and cyclic AMP. Brain temperature reached 70-80°C within 15-20 seconds of microwave exposure. Complete and simultaneous inactivation of cholinesterase, phosphodiesterase, and adenyl cyclase occurred throughout the brain at temperatures of 60-75°C. Acetylcholine levels were higher than literature values, free choline was significantly lower at 28.7 nmoles/mg whole brain, and cyclic AMP levels were comparable to those from rapid freezing.

Non-radiation heating produced evoked potential changes comparable to microwave heating of the same magnitude. Both microwave and exchanger heating decreased latency only in late components of the evoked potential. Concurrent cooling during radiation reduced or reversed the latency changes, showing they track temperature direction and magnitude.

Erythrocyte counts, radioactive iron incorporation, and leukocyte counts did not differ between groups. Bone marrow cellularity, chromosome aberrations, blood chemistry, fetal development, histology, leukemia, and mammary tumor assays showed no acute effects.

The mean daily irradiation value was 30.7 with a range of 6.5 to 97.1, and the measurement error was stated as + 30%. No significant differences in EEG findings were found between the exposed group and the control group. A significant coincidence was found between headache incidence and EEG abnormality percentage, particularly for migraine. The authors concluded that electromagnetic energy at the exposure dose did not damage the central nervous system and that EEG abnormalities should be assessed in relation to migraine incidence.

Researchers used a Q-switched neodymium laser at 1.06 µm to determine retinal damage thresholds in 100 rhesus monkey eyes. Each eye was exposed to five pulse configurations: single pulse, 10 pps for 0.5 sec, 10 pps for 1 sec, 20 pps for 0.5 sec, and 20 pps for 1 sec. Probit analysis showed no significant difference between the single-pulse ED-50 and the peak-pulse ED-50s in any pulse train. For average pulse energy, the 20 pps 0.5 sec and 20 pps 1 sec ED-50s were significantly lower than the single-pulse ED-50.

The paper proposes that absorbed microwave radiation creates thermal gradients in the semicircular canals, producing convective torque that mimics natural vestibular simulation. The analysis derives a detection threshold of 35 mW/cm², which may be significantly lower when resonance absorption occurs in small heads. Nystagmus onset is predicted at incident power densities between 100 and 400 mW/cm² depending on intracranial absorption patterns.
