How extremely low frequency (ELF) electromagnetic fields (such as power line exposure) impacts brain activity is today an intense area of research. One challenge is to unveil transduction mechanisms allowing ELF to interact with brain tissue. Thus, we present a cortical network model receiving internal and external stimuli. Using frequency analysis, we study how these stimuli durably modulate n...

Electromagnetic fields (EMFs) are present throughout the modern world and are derived from many man-made sources including overhead transmission lines. The risks of extremely-low frequency (ELF) electromagnetic fields are particularly poorly understood especially at high field strengths as they are rarely encountered at ground level. Flying insects, however, can approach close to high field str...

BACKGROUND The effects of extremely low frequency electromagnetic fields (ELF-EMF) on Toxoplasma gondii have not been explained yet. The aim of this study was to assess the possible effects of ELF-EMF on growth, survival time and viability of Toxoplasma gondii. In addition, the life span of Toxoplasma infected animals was investigated. METHODS Sixty adult male BALB/c mice were used for in viv...

This paper reviews experimental studies on the effects of radiofrequency (RF), extremely low frequency (ELF), and intermediate frequency (IF) electromagnetic fields on animal development. Numerous studies have shown that RF fields are teratogenic at exposure levels sufficiently high to cause significant increase of temperature. There is no consistent evidence of RF field effects at nonthermal e...

Interest in electromagnetic field (EMF) treatments has increased rapidly in recent years due to its advantages over other treatments for tissue healing and infection. Benefits include low-cost, ready availability, ease of localized application, few if any sideeffects, and indefinite shelf life. Immunological studies show that low-intensity EMF can interact with cells and tissues, providing a la...

the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals i...

In the present study, we examined the effects of extremely low-frequency (ELF) electromagnetic fields on morphine-induced conditioned place preferences in rats. During the conditioning phase (12 days), three groups of rats were placed in a sensory cue-defined environment paired with morphine (10mg/kg, i.p.) following exposure to either 20 Hz (1.80 mT) or 50 Hz (2.20 mT) or sham electromagnetic ...

OBJECTIVE Numerous studies have demonstrated the utility of extremely low frequencies (ELF) electromagnetic fields in clinical practice. Moreover, the effects of these fields seems to depend on their respective codes (frequency, intensity, waveform). In our study we want to value the effects of the TAMMEF (Therapeutic Application of a Musically Modulated Electromagnetic Field) system, which fie...

AIMS Typhoid is a serious disease difficult to be treated with conventional drugs. The aim of this study was to demonstrate a new method for the control of Salmonella typhi growth, through the interference with the bioelectric signals generated from the microbe during cell division by extremely low frequency electromagnetic waves (ELF-EMW-ELF-EM) at resonance frequency. METHODS AND RESULTS Is...
