Abstract	Cilj rada bio je proučiti i predočiti elektrofiziologiju i funkcioniranje neurona, njegove membrane i sinapsi te mehanizme širenja signala, zajedno s popratnim jednadžbama i modelima membrane. Prikazani su i alati za računalnu simulaciju neurona: NEURON i SENN. NEURON je obrađen samo teoretski, dok je SENN i praktično korišten te mu je detaljno objašnjen princip rada. Fokus rada bio je na elektrostimulaciji u ELF području koja je u radu obrađena s dva aspekta: medicinska primjena za duboku stimulaciju mozga (DBS) te djelovanje nenamjernog izlaganja ljudi elektromagnetskom polju. Provedena je i prikazana simulacija podražljivosti neurona računalnim alatom SENN, gdje je prikazan odziv na nekoliko vrsta signala. Prikazane su SF i SD krivulja za signal DBS-a. Pokazan je učinak blokiranja živca kontinuiranim sinusnim signalom velike amplitude. Na kraju, prikazan je i inhibicijski učinak vanjskog sinusnog električnog polja frekvencije 50 Hz na slijedove fizioloških akcijskih potencijala. Iz rezultata se može zaključiti da čak i pri vanjskom sinusnom elektromagnetskom polju od samo 20% amplitude iznosa praga dolazi do inhibicije fizioloških akcijskih potencijala.
Abstract (english)	The aim of this master thesis was to study and to present the electrophysiology and functioning of a neuron, its membrane and synapses, and to describe the mechanisms of signal propagation, along with the matching equations and membrane models. Neuron computer simulation tools were presented: NEURON and SENN. NEURON was only explained theoretically, while SENN was used experimentally and its work principles were explained in details. Focus of the thesis was on electrostimulation in ELF range, which was considered from two aspects: medical application for deep brain stimulation (DBS), and the effect of unintentional human exposure to electromagnetic fields. Simulation of neuron excitability using SENN was performed, where responses to several stimuli are presented. SF and SD curves are shown for DBS signals. The effect of nerve blocking by continuous high-amplitude sinusoid signal was demonstrated. Finally, the inhibition effect of the external sinusoidal 50 Hz electric field on the physiological signaling was demonstrated. The results support a conclusion that the external electric field stimulation with only 20% of the amplitude of the excitability threshold results with the inhibition of the physiological action potentials.
