Propagating Interfaces in a Two-Layer Bistable Neural Network
The dynamics of propagating interfaces in a bistable neural network is investigated. We consider the network composed of two coupled 1D lattices and assume that they interact in a local spatial point (pin contact). The network unit is modeled by the FitzHugh-Nagumo-like system in a bistable oscillator mode. The interfaces describe the transition of the network units from the rest (unexcited) st...
متن کاملModeling Bistable Perceptionwith a Network of Chaotic Neurons
When an ambiguous stimulus is observed, our perception undergoes dynamical changes between two states, a situation extensively explored in association with the Necker cube. Such phenomenon refers to bistable perception. Here, we present a model neural network composed of forced FitzHugh-Nagumo neurons, implemented also experimentally in an electronic circuit. We show, that under a particular co...
متن کاملLocalized modes and bistable scattering in nonlinear network junctions.
We study the properties of junctions created by the crossing of N identical branches of linear discrete networks. We reveal that for N>2 such a junction creates a topological defect and supports two types of spatially localized modes. We analyze the wave scattering by the junction defect and demonstrate nonzero reflection for any set of parameters. If the junction is nonlinear, it is possible t...
متن کاملBistable network behavior of layer I interneurons in auditory cortex.
GABAergic interneurons in many areas of the neocortex are mutually connected via chemical and electrical synapses. Previous computational studies have explored how these coupling parameters influence the firing patterns of interneuronal networks. These models have predicted that the stable states of such interneuronal networks will be either synchrony (near zero phase lag) or antisynchrony (pha...
متن کاملA Genetic Network Conferring Canalization to a Bistable Patterning System in Drosophila
To achieve the "constancy of the wild-type," the developing organism must be buffered against stochastic fluctuations and environmental perturbations. This phenotypic buffering has been theorized to arise from a variety of genetic mechanisms and is widely thought to be adaptive and essential for viability. In the Drosophila blastoderm embryo, staining with antibodies against the active, phospho...
