Recent work has also considered an explicit constructive approach to heteroclinic networks to realise arbitrary directed networks as a heteroclinic attractor of a coupled cell system [247] or as a closely-related excitable network attractor that appears at a bifurcation of the heteroclinic attractor [259].
In the fully excitable network, the response rate increased linearly with number of cells activated (Fig. 5 B). Figure 5 B also shows that dendritic nonlinearity kicks in even when a small percentage of the cells are activated via the thalamic input (compare black and color lines).
Self-excitable networks have communication channels that transmit information in a higher rate for a large range of the coupling strength.
Non-self-excitable networks have communication channels that transmit information in a higher rate for a small range of the coupling strength, however, they have channels that transmit reliable information in a moderate rate for large range of coupling strengths.
Self-excitable networks, namely those that have a majority number of self-excitable channels, have the topology of a perturbed star, i.e., they are composed of a central neuron connected to most of the other outer neurons, and some outer neurons sparsely connected among themselves.
Therefore, if a large amount of information is desired to be transmitted point-to-point in a non-self-excitable network, easily synchronizable networks are required.
The self-excitable network has thus a topology which can be considered to be a model for mini-columnar structure of the mammalian neocortex [19].
Here we show that, the synchronizability and sensitivity of excitable neural networks can be tuned by diversity in the connections strengths.
The country's thicket of excitable cable-news networks reports on nothing else.Mr Hazare's campaign has turned him from a noted social reformer into a national figure.
Dynamic actin networks are excitable.
In this early phase, chloride mediated neurotransmission is excitatory [51], so the spontaneous activity is intense and in the form of long-lasting bursts alternated by periods of quiescent activity, due to the hyper excitable nature of the networks.
