Overview

• Integrate-and-Fire, introduced in 1907, is the simplest model of a spiking neuron

• The Leaky Integrate-and-Fire makes the output sensitive to the timing of inputs by adding a memory loss element

• The Integrate-and-"Tire" adds hyperpolarization to the Leaky Integrate-and-Fire

• Integrate-and-Fire lacks a number of characteristics of the Hodgkin-Huxley model such as a variable threshold
