We use a supervised learning paradigm to derive a synaptic update rule that optimizes by gradient ascent the likelihood of postsynaptic firing at one or several desired firing times. ...
This suggests that synaptic updates with an STDP function based on pairs of pre-and postsynaptic spikes is close to optimal in the pattern detection paradigm. ...
In the presence of a teaching input and firing rate constraints, a weak reset of the membrane potential after the spike means that the neuron effectively has a depolarizing spike after potential (DAP). ...
