文摘

Effects of a shortcut on rotating waves in a ring of sigmoidal neurons are considered. A kinematical equation for the propagation of wave fronts in a rotating wave is derived. Rotating waves can be stabilized in the presence of an inhibitory shortcut. Dynamical metastability of rotating waves is lost in the presence of an excitatory shortcut.
