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…

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…

Jan 1, 2014
This double-blind, randomized, crossover study examined whether 30 minutes of near-field LTE radiofrequency exposure near the right ear alters resting-state brain activity measured by fMRI. The authors report decreased ALFF in multiple temporal and frontal/paracentral regions after real exposure compared with sham,…
