Behavioral Alterations in Zebrafish Induced by LF-EMF Exposure: A Detailed Analysis

Abstract

The field of wireless mobile technology continues to progress with each passing decade, resulting in improvements to previous generations. However, this advancement also leads to the creation of significant electromagnetic fields (EMF). The impact of EMF on anxiety-like behavior remains a subject of debate. Stress and anxiety are the states where the body's equilibrium is disrupted by various reactions triggered by external stimuli, leading to emotional and behavioral alterations. Behavior serves as the primary observable indicator of stress. Hence, it is important to thoroughly investigate the consequences of EMF radiation, as it does not reverse the behavioral changes caused by stress. The present study was carried out on Zebrafish (Danio rerio) to examine the effects of LF-EMF. The three behaviors considered in this study were scototaxis, thigmotaxis, and diving responses in response to LF-EMF (50Hz). The study showed significant behavioral modifications which included a preference for darkness and avoidance at the center. The erratic movements and freezing behavior were altered due to LF-EMF exposure. Thus, it was concluded that LF-EMF (50Hz) has the potential to induce anxiety-like behavior in zebrafish. Future research will encompass biochemical and histological parameters to gain a better understanding of the potential consequences of LF-EMF.
