Variations of the spontaneous electrical activities of the neuronal networks imposed by the exposure of electromagnetic radiations using computational map-based modeling.

Research RF Safe Research Library Jan 1, 2023

This computational neuroscience study models a ring of three coupled Rulkov neurons to examine how electromagnetic induction may change spontaneous neuronal network activity. The abstract reports that magnetic field effects depend on the network’s initial dynamical regime and synaptic strength, including elimination…

Regulation of skeletal myogenesis in C2C12 cells through modulation of Pax7, MyoD, and myogenin via different low-frequency electromagnetic field energies.
