This animal study examined whether EMF from a 90 kHz magnetic-coupling resonant wireless power transfer (WPT) system affects mouse cognition and hippocampal neuronal excitability. Mice were exposed for 2, 4, or 8 weeks and assessed with a Novel Object Recognition test and dentate gyrus patch-clamp recordings. The…

Jan 1, 2024
This rat study used a head-only 900 MHz GSM exposure system to assess brain activity changes via c-Fos imaging and to test spatial memory performance. Acute exposure (2 h) was associated with dose-dependent, region-specific increases in c-Fos expression, while repeated pre-training exposures were associated with…

This animal study exposed 40 adult male rats to a 10 Hz (4 mT) extremely low-frequency electromagnetic field for 1 hour daily for either 7 or 30 days. The authors report improved spatial memory after prolonged (30-day) exposure, alongside increased hippocampal BDNF levels. They also note a significant body weight…

This animal experiment assessed visual memory, cortisol, GR gene expression, and amygdala volume in four male rhesus macaques exposed to a 12 Hz, 0.7 μT ELF magnetic field. The exposed monkeys reportedly showed improved visual memory and reduced serum cortisol and GR gene expression, while controls did not show…

Jan 1, 2018
This animal study exposed Wistar rats to microwave radiation (30 mW/cm for 6 minutes, three times per week for six weeks) and assessed cognition, hippocampal dendritic spines, ultrastructure, and SNK-SPAR pathway molecules. The authors report impaired spatial learning and memory, dendritic spine loss/shrinkage, and…

Jan 1, 2018
This animal study used an in vivo microwave exposure model (30 mW/cm) and reports reversible neuronal injuries in rats. The authors observed cognitive impairment and synaptic plasticity injury in hippocampal neurons following exposure. Autophagy was activated, and autophagosomes showed increased association with…

Jan 1, 2017
This mouse study examined whether 50 Hz, 1 mT electromagnetic field exposure affects working memory and hippocampal electrophysiology. The authors report reduced Y-maze working memory performance after 3 days of EMF exposure, accompanied by decreased hippocampal firing rates. They also report reduced theta and…

Mar 19, 2015
This animal study exposed 108 male Sprague-Dawley rats to 900 MHz EMF (1 mW/cm2) or sham for 14 or 28 days (3 h/day). The authors report that 28-day exposure was associated with impaired spatial memory, BBB permeability damage, and ultrastructural changes in hippocampus and cortex. They also report increased mkp-1…
The Distracting Effects of a Ringing Cell Phone: An Investigation of the Laboratory and the Classroom Setting.

Jan 1, 2009
This paper reports four experiments examining how a ringing cell phone affects cognitive performance in laboratory tasks and a college classroom lecture. In the lab, auditory conditions (including a standard cell phone ring) produced slower responses than silence, with slower recovery in the ring and song conditions.…
