Spike-timing-dependent Plasticity
Slowness: An Objective for Spike-Timing-Dependent Plasticity?
... Thus on an abstract level SFA seems to capture an important aspect of cortical information processing. However, SFA as a technical algorithm is biologically rather implausible. There is in particular one step in its ...

A Spiking Neural Network Model of the Medial Superior Olive using Spike Timing Dependent Plasticity for Sound Localisation
... In a related approach but targeting lower latency responses, Smith (2001) employed the use of depressing synapses to detect the onsets in a phase-locked sound signal. It was observed that these onsets could be used to ...
