Feb 26, 2026
This randomized, between-subjects study in 98 healthy volunteers tested whether patterned EMF stimulation alters Digit Span performance and EEG activity. Theta-Burst stimulation reduced working memory (Digit Span Backward) and was associated with increased high-alpha activity in frontal regions. Theta-Gamma…
The impact of smartphone use on working memory in college students: a functional near-infrared spectroscopy study.

Jan 1, 2025
This study compared 42 college students grouped by high versus low screen time during a 2-back working memory task while measuring brain activity with fNIRS. The low screen time group performed better on working memory accuracy/hit rate, while reaction time and false alarms did not differ. Neuroimaging results…
Mobile phone use for 5 minutes can cause significant memory impairment in humans.

Jan 1, 2017
This study assessed working memory before and after 5 minutes of mobile phone use using a brief computerized 10-word recall task. The experimental group showed worse performance immediately after phone use, with partial improvement 5 minutes later, while the control group improved across repeated tests without phone…
Theta-gamma coupling in hippocampus during working memory deficits induced by low frequency electromagnetic field exposure.

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…

Jan 1, 2016
This mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…
Spatial learning, monoamines and oxidative stress in rats exposed to 900 MHz electromagnetic field in combination with iron overload.

Jan 1, 2014
This animal study tested whether 900 MHz EMF exposure, alone or combined with brain iron overload, affects cognition and brain biochemistry in Long-Evans rats. EMF-exposed rats showed impairment in an object exploration task and changes in monoamine content (notably in the hippocampus), while other spatial…
