In runtime mode, you can switch off an object by setting its active attribute to False. This can be useful to switch inputs/monitors on/off between runs or when using the store/restore mechanism (because you are not allowed to add/remove objects in that case). This does not work in standalone mode, e.g. the following continues to integrate v while in runtime it would remain constant after the first run:

from brian2 import *
set_device('cpp_standalone', build_on_run=False)
group = NeuronGroup(1, 'dv/dt = -v/(10*ms) : 1')
group.v = 1
mon = StateMonitor(group, 'v', record=0)
run(5*ms) = False

plot(mon.t/ms, mon[0].v)
