Exposure to magnetic field via cell phones reduced pyramidal neuron numbers and increased ischemic neurons in the cortex of rats.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to magnetic fields via cell phones during prenatal and postnatal periods until the rats were 80 days old. The study measured blood parameters and neurons in the brain of rats. Magnetic field exposure decreased pyramidal neuron numbers 51.15% and increased ischemic neuron numbers 73% at the cortex region of the brain. In the hippocampus, magnetic fields increased the amount of ischemic neurons three-fold compared to the control, while hippocampal pyramidal cell numbers were not affected.

Why This Matters

Animals were classified into three groups: control, Magnetic Field, and F2 groups. During the study, the phone was in standby mode for a whole day and in talking mode for 30 min per day. Cell phone waves were associated with an increased blood glucose level, rising from 96.52 ± 5.64 mg/dl to 132.14 ± 5.93 mg/dl. Serum protein level also increased, from 131.14 ± 6.19 mg/dl to 319.29 ± 6.73 mg/dl compared to control. Blood cholesterol concentration did not show statistically significant differences between the groups compared to the control. Weekly weight gain decreased in all groups compared to the control. Vascular dilatations increased clearly in the F2 group.
