A very simple example Brian script to show how to implement an integrate and fire model. In this example, we also drive the single integrate and fire neuron with regularly spaced spikes from the SpikeGeneratorGroup.

from brian import *

tau = 10 * ms
Vr = -70 * mV
Vt = -55 * mV

G = NeuronGroup(1, model='V:volt', threshold=Vt, reset=Vr)

input = SpikeGeneratorGroup(1, [(0, t * ms) for t in linspace(10, 100, 25)])

C = Connection(input, G)
C[0, 0] = 2 * mV

M = StateMonitor(G, 'V', record=True)

G.V = Vr
run(100 * ms)
plot(M.times / ms, M[0] / mV)
show()
