Prenatal exposure to 1800 MHz and WiFi radiofrequency may affect the behavioral and cognitive development of offspring rats, which may be associated with altered mRNA expression of NMDARs in the hippocampus.

Plain English Summary

Summary written for general audiences

Pregnant rats were exposed to radiofrequency fields starting on day 21 of pregnancy, and offspring were tested with Y maze at 3 weeks, open field at 7 weeks, and hippocampal NMDAR expression at 9 weeks. The 1800 MHz and 1800 MHz + WiFi groups showed a downward trend in body weight, and the WiFi group opened eyes earlier than controls. In open field tests, the 1800 MHz + WiFi group had shorter overall path length and delayed stationary time, the WiFi group had shorter path length and increased velocity in the error arm, and the 1800 MHz + WiFi group showed increased central area activity. Both exposure groups down-regulated NR2A and NR2B and up-regulated NR2D, NR3A, and NR3B, while the WiFi group also up-regulated NR1 and NR2C.

Quick Questions About This Study

Pregnant female rats were exposed to radiofrequency fields beginning on the 21st day of pregnancy.
Offspring were tested with Y maze at 3 weeks postnatal, open field at 7 weeks postnatal, and hippocampal NMDAR expression was measured at 9 weeks postnatal.
The 1800 MHz and 1800 MHz + WiFi groups showed a downward trend in body weight, and the WiFi group opened eyes earlier than the control group.
The 1800 MHz + WiFi group had shorter overall path length and delayed stationary time, the WiFi group had shorter path length and increased velocity in the error arm, and the 1800 MHz + WiFi group showed increased central area activity.
Both the 1800 MHz + WiFi and WiFi groups down-regulated NR2A and NR2B and up-regulated NR2D, NR3A, and NR3B, while the WiFi group also up-regulated NR1 and NR2C.
