Adaptively coupled phase oscillators with discontinuous plasticity rule — •Sören Christian Nagel1, Rico Berner1, Eckehard Schöll1, and Serhiy Yanchuk2 — 1Institut für theoretische Physik TU Berlin, Berlin, Germany — 2Institut für Mathematik TU Berlin, Berlin, Germany
Memory and the development of neuronal populations have been widely studied using discontinuous forms of spike timing-dependent synaptic plasticity (STDP). Despite the acceptance of these approaches in the field of neuroscience, very little is known about the dynamical features that are provided by the discontinuities.
For this purpose, we study a system of two coupled phase oscillators with STDP. Our analysis reveals various dynamical scenarios, namely, the appearance of a generalized fixed point as the source of in-phase synchrony, different types of limit cycles, and unexpected bifurcations due to the discontinuous STDP.
