Histamine inhibits the chemiluminescence response of human lymphocytes to Concanavalin A by interfering with early triggering events. The inhibition seems to be mediated via H2 receptors, acts immediately, and is reversible by washing. A longer incubation in a histamine-containing medium induces a refractory state of the cells. The inhibitory effect(More)
A discrete model of biological neural networks is used to find out how synchronized firing of neurons emerges in a randomly connected neural population. The objective is to understand the mechanisms underlying brain waves and to find and characterize conditions which support spontaneous switching from disordered to rhythmic population activity as in case of(More)
To Steve Smale who gifted to our community so much of new vision and inspiration. Abstract We consider statistical attractors of locally typical dynamical systems and their " ε-invisible " subsets: parts of the attractors whose neighborhoods are visited by orbits with an average frequency of less than ε ≪ 1. For extraordinarily small values of ε (say,(More)
