Abstract

Overview

The rapid advancement and ubiquitous use of mobile phones pose potential health risks, particularly from the emitted electromagnetic radiation (EMR). This study investigates the effects of EMR with frequencies of 1800-2100 MHz.

Aim

The research focuses on examining how this EMR range influences learning and memory functions and the microscopic structure of hippocampal Cornu Ammonis (CA3) neurons in mice.

Materials and Methods

  • Sample: 18 albino mice divided into three groups of six.
  • Procedure: Control, exposure for 30 minutes/day for 3 months (Group-II), and exposure for 60 minutes/day for 3 months (Group-III).
  • Assessment: Learning and memory assessed using the Hebb-Williams maze; brains analyzed post-mortem for neuronal structure.
  • Analysis: Data analyzed via ANOVA and LSD tests, significance marked at p<0.05.

Findings

Group-III mice, exposed for longer durations, showed significant impairment in achieving maze objectives and displayed notable neuronal damage in terms of structural deterioration and reduced cell count in the hippocampus. Group-II presented inconclusive effects.

Conclusion

Extended exposure to 1800-2100 MHz radiation compromises hippocampal function and structure, thereby endangering learning and memory capabilities.
