Abstract

Abstract Summary

Overview

In recent years, the exposure to radiofrequency (RF) fields has significantly increased with the growth of wireless and medical imaging technologies. This study investigates the effects of RF fields enhanced by brain implants in rodents.

Findings

• Rodents with neuronal recording electrodes were exposed to 950 MHz RF energy, and their brain activity, temperature, and behavior were monitored.
• Exposure to RF fields can cause rapid activation of neurons without causing thermal injury.
• Brain implants can intensify RF field effects, leading to reversible behavioral changes and a significant increase in brain temperature near the implant area.

Conclusion

The findings emphasize the necessity for meticulous safety evaluations of brain-implanted devices. Although risks exist, such implants might also serve therapeutic purposes in neurostimulation, provided the temperature rise remains within safe bounds.
