Abstract

EMF of power density from 0.4 to 10 mW/cm2 can influence forming the memory (imprinting). Showed the possibility to fix EMF modulated in embryonic brain during the natal period and conservation of this information after birth.

Main findings

Electromagnetic fields with power density 0.4 to 10 mW/cm2 were reported to influence memory formation (imprinting) in chicks. The authors report the possibility of "fixing" modulated EMF information in the embryonic brain during the natal period with conservation of this information after birth.

Outcomes measured

Memory formation (imprinting)
Retention/conservation of information after birth

Limitations

No frequency or modulation parameters reported in the abstract
No exposure duration or timing details beyond 'natal period'
No sample size or quantitative results provided
Outcome measures and methods for assessing imprinting are not described
