Single-Neuron Properties and Network Dynamics: A new
30.01.2015 · A prudent approach to understanding the function of the cerebral cortex begins with understanding the repertoire of its dynamics. In this thesis, I study how interactions between single neuron properties, synaptic coupling, and connectivity produce the microstate stability and macrostate activity exhibited by models of cortical circuits.

Spiking Neuron Models - Hugendubel Fachinformationen
Common assumptions in mean-field modeling are that explicit structural features or temporal details of neuronal networks (e.g. spiking dynamics of single neurons) are irrelevant for the analysis of complex mesoscopic dynamics and the emergent collective behavior is only weakly sensitive to the details of individual neuron behaviour (Breakspear Jirsa 2007).

Single-neuron models have been extensively studied, ranging from simple phenomenological models to complex multi-compartment neurons. However, linking mechanistic models of single-neurons to empirical observations of neural activity has been challenging.

This paper deals with Hopf bifurcation control for a single neuron model with delay-dependent parameters. It has been shown that the system without control cannot guarantee a stationary state. As the range parameter of the system passes a critical value, Hopf bifurcation occurs early.

Realistic Single Cell Modeling – from Experiment to
A model takes two documents and determines the more relevant one. We implement this concept in our model, the DirectRanker. If n>2 the approach is called listwise and the cost is computed on a whole list of sorted documents. Examples for these di erent approaches are [6,9,16] for pointwise, [2,4,8] for pairwise and [5,12,23] for listwise models.

NN-NEURON-ID is just a string which identifies a neuron. The string is not necessarily an XML ID because a PMML document may contain multiple network models where neurons in different models can have the same identifier. Within a model, though, all neurons (elements of NeuralInput and Neuron) must have a unique identifier.
Realistic Single Cell Modeling – from Experiment to
A delayed differential equation modelling a single neuron with inertial term subject to time delay is considered in this paper. Hopf bifurcation is studied by using the normal form theory of retarded functional differential equations. When adopting a nonmonotonic activation function, chaotic behavior is observed.
