State monitors are used to monitor time continuous [[StateVector|state variables]] such as the membrane voltage or GABA conductance, etc from [[NeuronGroup|NeuronGroups]]. Since these quantities are generally only locally available at individual nodes, each process writes it own file. Moreover, since a high frequency sampling of a state variable quickly generates massive amounts of data, a StateMonitor only records from a single neuron. To monitor multiple neurons also multiple monitors are required.

====== Example & Usage ======

<code cpp>
strin filename = "foo.mem";
StateMonitor * smon_mem = new StateMonitor( neurons_e, 7, "mem", filename.str() ,dt );
</code>

This code snipped sets up a [[StateMonitor]] to record from the [[NeuronGroup]] neurons_e. Specifically, the monitor records from the neuron with ID 7 and from the [[StateVector]] "mem" which is one of Auryn's [[default specifier]] for the membrane potential. The other remaining arguments pass the filename to record to as well as the sampling interval (here ''dt'' which corresponds to the integration timestep in Auryn.
