Firing Rate Models
... The average responses can change dynamically, but in general will correspond to some sort of relaxation to a known steady state response. The two quantities needed in the model are the inputs and the outputs of the neuron. Inputs can be currents, I, but here we use the synaptic gating variable, s (s ...

The gap between neurons is called the synapse. -The synapse acts as an electrical insulator, preventing an electrical charge from racing to the next cell. -To pass across the synaptic gap, or synaptic cleft, an electrical message must ...
