Mobile phone RF-EMR exposure significantly altered passive avoidance behaviour and hippocampal morphology in rats.

Plain English Summary

Summary written for general audiences

Healthy male albino Wistar rats were exposed to RF-EMR by giving 50 missed calls per day for 4 weeks with a GSM mobile phone in vibratory mode in the cage. Passive avoidance behaviour was significantly affected in exposed rats, shown as shorter entrance latency to the dark compartment compared to control rats. Marked morphological changes were observed in the CA3 region of the hippocampus of exposed rats compared to control rats. Mobile phone RF-EMR exposure significantly altered passive avoidance behaviour and hippocampal morphology in rats.

Why This Matters

The researchers evaluated the effect of RF-EMR from mobile phones on passive avoidance behaviour and hippocampal morphology in rats. After the experimental period, passive avoidance behaviour and hippocampal morphology were studied.
