Studies reported behavioral effects including shortening of human reaction times, of human circadian rhythms, and of subjective estimates of the passage of time in the monkey, using electric fields at 5-15 Hz with a peak amplitude of 2-10 V/m in air. There was a remarkable tuning curve for different modulation frequencies, with increased calcium efflux from the cortex at modulation frequencies between 9 and 20 Hz, but very little increase outside this frequency band. Pulsed electric stimulation of cat cortex with gradients in the range 20-60 mV/cm increased the efflux of both calcium and GABA.

The narrow-range probe achieved a maximum sensitivity of 0.5 SmW/cm² in X band and a response time under 10 ms. The wide-range probe showed a maximum sensitivity of 5 SmW/cm² and a response time of about 100 ms. Calibration curves were obtained at 0.4 GHz, 1.4 GHz, and 2.4 GHz, and sensitivity decreased toward lower microwave frequencies.

Experiments using a parallel plate waveguide measured RF absorption in rats and biological-phantom prolate spheroids across frequencies and polarizations. The results correlated well with free-space irradiation findings. Peak absorption occurred when the electric field was parallel to the long body axis at frequencies where the body length was about one-quarter wavelength, with absorption 2.5 to 3.5 times the shadow cross-section.

Muscle penetration depth followed the expected frequency inverse behavior and matched predictions from lower-frequency data by Schwan and Li. Fat penetration depth agreed within 50% of extrapolated data and showed relatively large values of several millimeters around 50 GHz. Muscle tissue measurements indicated substantial multimoding, so the reported dielectric constant and conductivity values represent only upper limits.

Thirty-four subjects were exposed to weak constant vertical magnetic fields of about 5,000 gammas, a 10% increment over the ambient geomagnetic field, in a repeated-measures design with two sessions. Calculation attempts were significantly lower in the first trial of the field-on session than in the second trial, the field-off session showed no significant change, and the overall ANOVA across trials was significant.

Researchers gave CB 154 to five green monkeys with brainstem lesions that caused tremor. A single dose of CB 154 stopped tremor for about one hour. Repeated dosing stopped tremor for at least 48 hours, with reduced tremor lasting another 24-48 hours after treatment ended. Repeated CB 154 also caused moderate involuntary movements that lasted less long than the tremor relief. CB 154 reduced hypokinesia in three of the five monkeys.

The apparatus is a 6 m long, temperature-controlled water alley with automatically raised and lowered end platforms that record swim speed on each traverse. Water temperature was held at 24°C with a gradient not exceeding .3°C across the alley. An avoidance-conditioning and dunking procedure trained more than 90% of rats to swim reliably at 23°C. The platform rest period used in most experiments was 30 seconds. The automated system operated reliably for extended sessions with trained rats.

Only 10 documented cases of EMI affecting pacemakers were found, and none were serious or fatal. The authors concluded that environmental EMI does not constitute an important clinical problem for pacemaker patients at this time.
