Abstract

OBJECTIVE: To investigate whether exposure to a pulsed high-frequency electromagnetic field (pulsed EMF) emitted by a mobile phone has short-term effects on the inhibitory control of saccades. METHODS: A double-blind, counterbalanced crossover study design was employed. We assessed the performance of 10 normal subjects on antisaccade (AS) and cued saccade (CUED) tasks as well as two types of overlap saccade (OL1, OL2) task before and after 30 min of exposure to EMF emitted by a mobile phone or sham exposure. RESULTS: After EMF or sham exposure, we observed a slight but significant shortening of latency in the CUED and OL2 tasks. AS amplitude decreased as well as the saccade velocities in the AS, CUED, and OL1 tasks after exposure. These changes occurred regardless of whether exposure was real or sham. The frequencies of pro-saccades in the AS task, saccades to cue in the CUED task, and prematurely initiated saccades in the overlap (OL2) task did not change significantly after real or sham EMF exposure. CONCLUSIONS: Thirty minutes of mobile phone exposure has no significant short-term effect on the inhibitory control of saccades. SIGNIFICANCE: The cortical processing responsible for saccade inhibition is not affected by exposure to EMF emitted by a mobile phone.

Main findings

In a double-blind, counterbalanced crossover study, several saccade metrics (e.g., CUED and OL2 latency shortening; AS amplitude and velocities in AS/CUED/OL1) changed after exposure, but these changes occurred regardless of real versus sham exposure. Measures more directly related to inhibitory control (e.g., pro-saccade frequency in AS, saccades to cue in CUED, premature saccades in OL2) did not change significantly after real or sham exposure. The authors conclude that 30 minutes of mobile phone EMF exposure has no significant short-term effect on inhibitory control of saccades.

Outcomes measured

  • Inhibitory control of saccades
  • Antisaccade (AS) task performance (e.g., amplitude, velocity, pro-saccade frequency)
  • Cued saccade (CUED) task performance (e.g., latency, velocity, saccades to cue)
  • Overlap saccade tasks (OL1, OL2) performance (e.g., latency, velocity, premature saccades)

Limitations

  • Small sample size (n=10)
  • Short-term exposure only (30 minutes)
  • Exposure parameters (e.g., frequency, SAR) not reported in abstract
