Auditory brainstem response changes during exposure to GSM-900 radiation: an experimental study.

Area of Science:

• Neuroscience
• Electrophysiology
• Auditory System Research

Background:

• Mobile phones emit electromagnetic fields (EMF) that raise health concerns.
• The auditory pathway's electrophysiological responses to EMF exposure require further investigation.

Purpose of the Study:

• To examine time-related electrophysiological changes in the auditory pathway during mobile phone EMF exposure.
• To assess the impact of GSM-900 radiation on auditory brainstem responses (ABRs).

Main Methods:

• Thirty healthy rabbits were exposed to simulated GSM-900 mobile phone radiation for 60 minutes.
• Auditory brainstem responses (ABRs) were recorded at regular intervals during EMF exposure.
• Latency of ABR waves and interwave intervals were analyzed.

Main Results:

• Significant delays in absolute latency of ABR waves III-V were observed after 15, 45, and 60 minutes of exposure (p < 0.05).
• Interwave latencies I-III, I-V, and III-V showed statistically significant prolongation after 30 and 60 minutes of radiation.
• No significant changes were noted in the contralateral ear, and ABRs returned to baseline 24 hours post-exposure.

Conclusions:

• Mobile phone EMF exposure can induce measurable electrophysiological changes in the auditory system.
• These findings suggest the auditory pathway reacts to EMFs similarly to other stressors.
• The observed effects were temporary, with recovery within 24 hours.
