Modulation of synchrony without changes in firing rates

J Heinzle, P König, RF Salazar - Cognitive Neurodynamics, 2007 - Springer
It was often reported and suggested that the synchronization of spikes can occur without
changes in the firing rate. However, few theoretical studies have tested its mechanistic …

[HTML][HTML] Influence of delayed conductance on neuronal synchronization

PR Protachevicz, FS Borges, KC Iarosz… - Frontiers in …, 2020 - frontiersin.org
In the brain, the excitation-inhibition balance prevents abnormal synchronous behavior.
However, known synaptic conductance intensity can be insufficient to account for the …

Dynamics of spiking neurons connected by both inhibitory and electrical coupling

TJ Lewis, J Rinzel - Journal of computational neuroscience, 2003 - Springer
We study the dynamics of a pair of intrinsically oscillating leaky integrate-and-fire neurons
(identical and noise-free) connected by combinations of electrical and inhibitory coupling …

Electrical synapses and synchrony: the role of intrinsic currents

B Pfeuty, G Mato, D Golomb, D Hansel - Journal of Neuroscience, 2003 - Soc Neuroscience
Electrical synapses are ubiquitous in the mammalian CNS. Particularly in the neocortex,
electrical synapses have been shown to connect low-threshold spiking (LTS) as well as fast …

When inhibition not excitation synchronizes neural firing

C Van Vreeswijk, LF Abbott… - Journal of computational …, 1994 - Springer
Excitatory and inhibitory synaptic coupling can have counter-intuitive effects on the
synchronization of neuronal firing. While it might appear that excitatory coupling would lead …

[HTML][HTML] Inhibition potentiates the synchronizing action of electrical synapses

B Pfeuty, D Golomb, G Mato, D Hansel - Frontiers in Computational …, 2007 - frontiersin.org
In vivo and in vitro experimental studies have found that blocking electrical interactions
connecting GABAergic interneurons reduces oscillatory activity in the µ range in cortex …

Dispersion and time delay effects in synchronized spike–burst networks

VK Jirsa - Cognitive neurodynamics, 2008 - Springer
We study spike–burst neural activity and investigate its transitions to synchronized states
under electrical coupling. Our reported results include the following:(1) Synchronization of …

Conditions for propagating synchronous spiking and asynchronous firing rates in a cortical network model

A Kumar, S Rotter, A Aertsen - Journal of neuroscience, 2008 - Soc Neuroscience
Isolated feedforward networks (FFNs) of spiking neurons have been studied extensively for
their ability to propagate transient synchrony and asynchronous firing rates, in the presence …

Effects of synaptic synchrony on the neuronal input-output relationship

X Li, GA Ascoli - Neural computation, 2008 - ieeexplore.ieee.org
The firing rate of individual neurons depends on the firing frequency of their distributed
