Coherence Resonance in an Autapse Neuron Model with Time Delay
Gautam C Sethia, Juergen Kurths, Abhijit Sen
We study the noise activated dynamics of a model {\it autapse} neuron system that consists of a subcritical Hopf oscillator with a time delayed nonlinear feedback. The coherence of…

Bursting in a Subcritical Hopf Oscillator with a Nonlinear Feedback
Gautam C Sethia, Abhijit Sen
Bursting is a periodic transition between a quiescent state and a state of repetitive spiking. The phenomenon is ubiquitous in a variety of neurophysical systems. We numerically st…

Excitable Dynamics in the Presence of Time Delay
Gautam C Sethia, Abhijit Sen
The spiking properties of a subcritical Hopf oscillator with a time delayed nonlinear feedback is investigated. Finite time delay is found to significantly affect both the statisti…
