چکیده

An analog MOS circuit that imitates bursting properties of spiking neurons is proposed and fabricated. The circuit consists of the Oregonator device that can easily be implemented on analog CMOS LSIs. We demonstrate temporal properties of the proposed circuits by SPICE and fabricated ICs.

Bursting Near homoclinic bifurcation in Two Coupled Chua oscillators

We report experimental observation of cycle-cycle bursting near homoclinic bifurcation in a selfoscillating Chua oscillator when it is diffusively coupled to another excitable Chua oscillator. The excitable oscillator induces an asymmetry in the self-oscillating Chua oscillator via coupling. The coupling strength controls the strength of the asymmetry that plays a key role in transition to burs...

Synchronization of Coupled Neural oscillators with Heterogeneous delays

We investigate the effects of heterogeneous delays in the coupling of two excitable neural systems. Depending upon the coupling strengths and the time delays in the mutual and self-coupling, the compound system exhibits different types of synchronized oscillations of variable period. We analyze this synchronization based on the interplay of the different time delays and support the numerical re...

Bursting induced by excitatory synaptic coupling in nonidentical conditional relaxation oscillators or square-wave bursters.

This work explains a mechanism through which the introduction of excitatory synaptic coupling between two model cells, one of which is excitable and the other of which is tonically active when uncoupled, leads to bursting in the resulting two-cell network. This phenomenon can arise when the individual cells are conditional relaxation oscillators, in that they can be tuned to engage in relaxatio...

Amplification of information transfer in excitable systems that reside in a steady state near a bifurcation point to complex oscillatory behavior.

We study the amplification of information transfer in excitable systems. We show that excitable systems residing in a steady state near a bifurcation point to complex oscillatory behavior incorporate several frequencies that can be exploited for a resonant amplification of information transfer. In particular, for excitable neurons that reside in a steady state near a bifurcation point to ellipt...

Chaotic bursting as chaotic itinerancy in coupled neural oscillators.

We show that chaotic bursting activity observed in coupled neural oscillators is a kind of chaotic itinerancy. In neuronal systems with phase deformation along the trajectory, diffusive coupling induces a dephasing effect. Because of this effect, an antiphase synchronized solution is stable for weak coupling, while an in-phase solution is stable for very strong coupling. For intermediate coupli...
