This simulation implements a variation of sim_epsp. A single presynaptic Poisson neuron provides input through a synapse which implements the Tsodyks Markram model [1]. The file records the presynaptic spiketrain, as well as the postsynaptic excitatory conductances and membrane voltage.

Running the program

The simulation can be invoked without any parameters. It creates the following command line output

zenke@merlin ~/auryn/build/home $ make sim_epsp_stp && ./sim_epsp_stp

The presynaptic Poisson neuron initially spikes at 1Hz for 5 seconds. The rate then switches to 50Hz for 0.5s after which it drops back to 1Hz.
