... The firing is caused by an influx of sodium. It takes a few milliseconds to ‘fire’ sending an electrical impulse to the synapse, the threshold of excitation must be exceeded for the neuron to fire. The connections of the neurons to other neurons determine whether the neuron is likely to fire or not ...
