TUESDAY, March 20 (HealthDay News) -- Mice exposed to cellphone radiation in-utero are more hyperactive and have impaired memory, according to an experimental study published online March 15 in Scientific Reports.
Tamir S. Aldad, from Yale University in New Haven, Conn., and colleagues exposed pregnant mice throughout gestation to radiation from muted and silenced cellular phones (800 to 1,900 Mhz) placed over the feeding bottle area, 4.5 to 22.3 cm from the mice. The phones were either on an uninterrupted active call or were deactivated.
Based on psychological and behavioral tests, the researchers found that the mice that had been exposed to radiation in-utero were hyperactive and had impaired memory. The behavioral changes were linked to altered neuronal developmental programming and defective glutamatergic synaptic transmission in the prefrontal cortex of the brain.
"We demonstrate that fetal radiofrequency radiation exposure led to neurobehavioral disorders in mice," Aldad and colleagues conclude. "The rise in behavioral disorders in developed countries may be, at least in part, due to a contribution from fetal cellular telephone radiation exposure."
