Figure 10 also shows ideal time courses for the implemented model with the same parameters and fitted amplitude and offset. The measurements agree well with these nominal curves even without calibrating any parameters. They differ mainly in the adaptation strength, i.e., in the ratio between highest and lowest PSC amplitude, which is smaller in the measured curves. This may be caused by time constants being too small, or by charge injection effects, resulting in voltage offsets during updates of the adaptation variables at incoming spikes.
