Summary

For comparison with experiments, NEST simulations should ideally be able to simulate measurable signals, like Local Field Potentials (LFPs) and Electroencephalography (EEG). However, point-neurons can not in themselves produce such signals, and additional tricks are needed. The hybrid scheme has previously been used to allow LFP calculation from NEST simulations through the Hybrid Scheme, but the extracranially measured EEG signals are more complicated, since they require a head model.
