AB  - Forty male rats of the Wistar ST strain were trained and observed for Sidman 
      avoidance (SA) for 7 weeks or for discriminative avoidance (DA) for 14 weeks to 
      determine the effects of exposure to a strong static-magnetic field. Before 
      avoidance conditioning was completed, rats in the SA group were exposed to the 
      static field at 0.6 T, 16 h/day for 4 days during the fifth week, and those in 
      the DA group were exposed for 6 h/day for 4 days during the seventh week. In the 
      SA conditioning, frequency of lever-pressing by exposed rats gradually decreased 
      during 1 week of exposure and stayed low for at least 2 weeks after exposure. 
      Frequencies of electric shocks received by the rats increased dramatically during 
      the second day of exposure and consistently stayed higher than those of control 
      rats. In the DA condition, exposed rats responded at lower rates than did control 
      rats throughout the observation period. They received more shocks during the 2 
      weeks following exposure. The data indicate that performance of avoidance 
      responses was inhibited by a comparatively long exposure to a strong magnetic 
      field.
