Ex Vivo Effect of 60 GHz MMW radiation on Leech Neuron Intracellular Calcium Alteration

Multiple studies showed various effects of millimeter wave (MMW) radiation in biological objects [1]. The most common subjects to observe are genetic apparatus, shifts in activity and structure of macromolecules and cell function. Reasonably, biological effects of MMW radiation on living tissues are associated with inevitable heating of the sample due to high water content. Nevertheless, opposite to conductive heating alterations in neuronal electrophysiological activity was reported. This induces the question regarding the intracellular calcium homeostasis in neurons, due to critical importance of intracellular level of free calcium for neuron's activity. This study indicated upregulation of free intracellular calcium in ex vivo experiment along with corelating morphological changes in the leech ganglia neuron.
