Rhythmic brain waves caused by the synchronous firing activity of neurons are believed to be
relevant for higher brain functions such as the attention and sleep-wake state switching. In the brain, cortical neurons, including interneurons, are anat...

Quasiperiodicity and chaos in a ring of unidirectionally coupled sigmoidal neurons (a ring neural oscillator) caused by a single shortcut is examined. A codimension-two Hopf–Hopf bifurcation for two periodic solutions exists in a ring of six neuro...

We study the intersection of double-flip (period-doubling) bifurcations in a parameter plane. We derive normal forms for discrete-time and continuous-time systems. Using these normal forms, we clarify the bifurcation structure around the flip-flip...

Bifurcations and chaos in a network of three identical sigmoidal neurons are examined. The
network consists of a two-neuron oscillator of the Wilson–Cowan type and an additional third
neuron, which has a simpler structure than chaotic neural netwo...

Electrical alternans is the alternating amplitude from beat to beat in the action potential of
the cardiac cell. It has been associated with ventricular arrhythmias in many clinical studies;
however, its dynamical mechanisms remain unknown. The re...
