Implementação do modelo integra-e-dispara para o potencial de ação neuronal em um circuito elétrico

Abstract

We use an electric circuit to implement the theoretical model for the action potential of a neuron. The model selected was the integrate-and-fire, which, despite its simplicity, captures important physiological characteristics of the neuron and is therefore the most used model in computational neuroscience simulations. The circuit is a resistor-capacitor type with special conditions for triggering of the action potential (implemented with transistors), that result in oscillations with relaxation. Our aims with this implementation were (i) to provide the field with a detailed methodology and (ii) allow an alternative visualization for the mathematical model described in such abstract language.
