Abstract

In the present study, we examined the effects of acoustic range electromagnetic field (EMF) on emotional-motivated behavior in genetically epilepsy-prone rats (GEPRs) of Krushinsky-Molodkina strain in Open field test. A 5-days exposure by EMF (10 -15 kHz, 1,5 mlTl, duration 20 min) resulted in partial or complete suppression of behavior seizure activity in GEPRs. The anxiety degree in irradiated GEPRs versus the controls (GEPRs without EMF exposure) was decreased, whereas the locomotion/exploratory activity was increased. A 5-days exposure by EMF in inbred white rats also changed the locomotion/exploratory activity in Open field test. We conclude that acoustic range of EMF can apply for suppression of behavioral manifestation of the seizure. These data support a potential role of EMF exposure in changing emotion regulation of anxiety, but the mechanisms of such influence are not known. Proposed biological mechanisms in anti-seizure and anxiolytic effects of EMF exposure in GEPRs might include normalization of neuroendocrine, neurotransmitter, and/or neurotrophic factors.
