Spatial learning deficit in the rat after exposure to a 60 Hz magnetic field
Bioeffects Seen
Authors not listed · 1996
Rats exposed to a 60 Hz magnetic field before each training session showed significantly retarded learning.
Plain English Summary
Summary written for general audiences
Rats were trained in ten daily sessions on a 12-arm radial maze to assess spatial memory. Exposure to a 60 Hz magnetic field at 0.75 mT for 45 minutes before each session significantly retarded learning.
Why This Matters
Pretreatment with the cholinergic agonist physostigmine before exposure reversed the field's effect on spatial learning. The researchers concluded that the spatial learning deficit was caused by the field's effect on cholinergic systems.
