In the present study, we examined the effects of chronic exposure (I and 2 weeks) to an extremely low-frequency magnetic field (ELFMF)
of 2 G intensity on memory in rats using an object recognition task. Comparable groups of rats were exposed for I, 2 or 4 weeks to ELFMF
and the following day blood samples were collected from each rat for the measurement of corticosterone level. Our results demonstrate that
exposure to ELFMF induces a significant increase in the level of corticosterone in blood plasma and is associated with impairment in
discrimination between familiar and novel objects. © 2002 Elsevier Science Inc. All rights reserved. |
