Neuron response to frequency-dependent spike trains
We
examine the response of type II excitable neurons to trains of synaptic
pulses, as a function of the pulse frequency and
amplitude. Similarly to the case of harmonic inputs, these neurons
exhibit a resonant behavior also for pulsed inputs. We interpret this
phenomenon in terms of the subthreshold
response of the neuron. In
the presence of dynamical trains of input pulses whose frequency varies
continuously in time, the receiving neuron synchronizes episodically to
the input pulses, whenever the pulse frequency lies within the neuron's
locking range.
