Evaluation of neuronal coupling dynamics

Biological Cybernetics, 1983
Temporary correlated activity of neuron assemblies is believed to play a substantial role for the brain's pattern recognition ability. To study the underlying principles of such mechanisms, a method is proposed for the characterization of the interneuronal and stimulus-response coupling changes of two periodically driven and simultaneously recorded ...

Mapping the dynamics of a bursting neuron

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
Abstract The anterior burster (AB) neuron of the lobster stom atogastric ganglion displays varied rhythmic behavior when treated with neuromodulators and channel-blocking toxins. We introduce a channelbased model for this neuron and show how bifurcation analysis can be used to investigate the response of this model to changes of its ...

Dynamics of moment neuronal networks

Physical Review E, 2006
A theoretical framework is developed for moment neuronal networks (MNNs). Within this framework, the behavior of the system of spiking neurons is specified in terms of the first- and second-order statistics of their interspike intervals, i.e., the mean, the variance, and the cross correlations of spike activity.

Dynamic mechanisms of neuronal outgrowth

1994
Publisher Summary What is the effect of changes in growth cone behavior or microtubule elongation on neuronal morphogenesis? And, how do these two key factors interact in neuronal outgrowth? These questions are subject of this chapter. Questions regarding the role of the growth cone in neuronal outgrowth are treated primarily. Questions regarding the

Single neuron dynamics and computation

Current Opinion in Neurobiology, 2014
At the single neuron level, information processing involves the transformation of input spike trains into an appropriate output spike train. Building upon the classical view of a neuron as a threshold device, models have been developed in recent years that take into account the diverse electrophysiological make-up of neurons and accurately describe ...

The Dynamic Neuron

2002
A comprehensive review of current research on synaptic plasticity. The traditional model of synapses as fixed structures has been replaced by a dynamic one in which synapses are constantly being deleted and replaced. This book, written by a leading researcher on the neurochemistry of schizophrenia, integrates material from neuroscience ...

On the stochastic dynamics of neuronal interaction

Biological Cybernetics, 1976
The response of many neurons in the nervous system is a nonlinear function of membrane potential. Nevertheless, if the membrane potentials are normally distributed then their covariance satisfies a linear equation. This suggests that information in the nervous system may be processed by correlations between membrane potentials, a hypothesis which is ...

Complex dynamics of neuronal thresholds

Neurocomputing, 2000
Abstract We study an integrate and fire model of an adapting neuron. Using two dynamic thresholds, we account for the complex long-term behavior of single neurons under periodic pulsed inputs. We find that the pattern of temporal response is that of a staircase of inter-spike interval values.

‘Dynamics of neuronal interactions’ cannot be explained by ‘neuronal transients’

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1995
In a recent paper, Vaadia et al. demonstrated that patterns of firing correlation between single neurons in the cortex of behaving monkeys can be modified within a fraction of a second. These changes occur in relation to sensory stimuli and behavioral events, and even without modulations of the neurons' firing rates.
