Blackwell and Reed 1985

Mice (male)

21-30 g

20 sham, 20 exposed

50-400 V/m, 15-50 Hz

Sleep-time exploration behavior

No effects

 

Rosenberg et al. 1981

Deer mice

5-15 mon

34 in plastic cages above ground, 21 grounded

100 kV/m, 10 Hz

Activity, circulation, CO2, oxygen, temperature

Transient activity and gas increase during inactive phase

 

Rosenberg et al. 1983

Deer mice

5-15 mon

8 sham, 60 exposed

10-75 kV/m, 60 Hz

Activity, blood gas

Transient increase with exposures of 50-75 kV/m

 

Blackwell 1986

Albino male rats (HMT)

250-400 g

200 recordings, 51 cells

100 V/m, 50, 30, and 45 Hz

Firing rate timed

No effect on rate at 15 and 30 Hz; firing time was dependent on field voltage

 

Creim et al. 1984

No effects

 

Easley et al. 1991

Baboons

5-6 yr

8 exposed, 8 sham

30 kV/m, 60 Hz; exposed 6 wk, 12 hr/day and 7 days/wk

Social behavior, passive affinity, tension, steroptopy

Social stress only in first 2 wk

 

Stern and Laties 1985

Rats (female)

Adult

5 own control

55 kV/m, 60 Hz

Operant detection

3-10 kV/m detection threshold

 

Hjeresen et al. 1980

Rats

Adult

8 sham, 32 exposed per experiment

0, 60, and 105 kV/m

Shuttlebox avoidance and general acuity

75 kV/m and greater in long 23.5 hr exposure leads to
