Jan 1, 2026
This pilot clinical trial evaluated a portable helmet system delivering electromagnetic field stimulation at gamma oscillation frequencies (70 100 Hz) in patients with cognitive impairment. Sixteen patients were included, with ten receiving stimulation after protocol refinement. MMSE scores increased on average from…

Jan 1, 2025
This study estimated thresholds and locus for human phosphene perception during non-invasive transcranial alternating current stimulation at 20, 50, 60, and 100 Hz. Perception depended significantly on stimulation intensity, with the lowest threshold at 20 Hz and no reported phosphenes at 100 Hz. The authors report…

This in vitro study exposed glioblastoma (CT2A), neuroblastoma (N2A), and non-tumor astrocyte (C8D1A) cell models to a 100 μT magnetic field across 20–100 Hz for 24–72 hours. The abstract reports decreased viability and proliferation in the tumor cell models within a frequency window centered at 50 Hz, while…

Jan 1, 2025
This animal study tested whether low-intensity theta burst patterned electromagnetic fields (TBEMF; 1 μT; bursts at 100 Hz) affect fear-related learning in planaria using a T-maze with aversive light. The light-only group showed behavioral changes consistent with learning to avoid the aversive arm, while TBEMF…

Jan 1, 2019
This in vitro study evaluated whether extremely low-frequency EMF exposure (100 Hz, 100 G) modifies the effects of temozolomide (100 µM) in human glioblastoma U87 cells over 120–144 hours. The authors report that combined treatment reduced stemness-associated markers (Nestin, CD133, Notch4) and increased GFAP…
Cytotoxicity of temozolomide on human glioblastoma cells is enhanced by the concomitant exposure to an extremely low-frequency electromagnetic field (100Hz, 100G).

Jan 1, 2017
This in vitro study tested whether an extremely low-frequency EMF (100 Hz, 100 G) could enhance temozolomide cytotoxicity in human glioma cell lines (U87 and T98G). The authors report that combined EMF and temozolomide increased apoptosis relative to either treatment alone and was accompanied by changes in…

Jan 1, 2013
This laboratory study examined pulsed magnetic field (PMF) pretreatment of soybean seeds (1500 nT) at 0.1–100 Hz for 5 hours/day over 20 days. The abstract reports increased germination rates for all PMF treatments, with 10 and 100 Hz showing the strongest responses, and improvements in several seedling growth and…
