ConceptAxonDelay

Related: ConceptTiming

Since neurons in the brain can connect to others a considerable distance away, and the neural spike travels along the axon so slowly, the pulse might arrive at the target synapses anywhere from 1 ms to tens of milliseconds later. This is ignored in the models presented so far but is significant for certain networks like determining the direction of incoming sound, and may be important in other future development. To compensate, the LIF neuron model carries a parameter of “Axon Delay” which determines the number of cycles that it takes for a spike to reach the target synapses.
