Low-intensity electromagnetic field (12.6 cm, 2375 MHz, power density 1 mW/cm²) produced retrograde amnesia in the rat passive avoidance test. No effect was registered of microwave irradiation on the open field behavior and the pain sensitivity.

Functional activity of the m-cholinergic receptors decreased, but their number increased in the brain cortex.

It is suggested that cholinergic system plays an important role in the effects of electromagnetic field on memory processes
