Description

Neurons are the most fundamental part of the nervous system and are diverse in structure and function containing a cell body, dendrites, and axons (Ludwig, et al., 2022). These electrically excitable cells receive and transmit electrical and chemical signals. These electrical impulses are known as action potentials in response to an input, and aids in the transmission of neurological information to neighboring neurons. An action potential (AP) is a rapid sequence of changes in the voltage across a membrane and it's an all-or-nothing event. It has three main stages: depolarization, repolarization, and hyperpolarization (Grider et al., 2023). Threshold depends on the shape of the sodium activation function near spike initiation (Platkiewicz & Brette, 2010). The value of that threshold sets the firing rate and determines the way neurons compute. The neuronal firing rate is defined as the number of spikes, divided by the duration of given spikes in a time interval (Tomar, 2019).
