Dynamic excitatory-inhibitory (E-I) balance is a paradigmatic mechanism invoked to explain the irregular low firing activity observed in the cortex. However, we will show that the E-I balance can be at the origin of other regimes observable in the brain. The analysis is performed by combining extensive simulations of sparse E-I networks composed of N spiking neurons with analytical investigations of low dimensional neural mass models. The bifurcation diagrams, derived for the neural mass model… 


Fast Global Oscillations in Networks of Integrate-and-Fire Neurons with Low Firing Rates
We study analytically the dynamics of a network of sparsely connected inhibitory integrate-and-fire neurons in a regime where individual neurons emit spikes irregularly and at a low rate. In the

It is shown that an unstructured, sparsely connected network of model spiking neurons can display two fundamentally different types of asynchronous activity that imply vastly different computational properties.
Coherent oscillations in balanced neural networks driven by endogenous fluctuations
A detailed analysis of the dynamical regimes observed in a balanced network of identical Quadratic Integrate-and-Fire (QIF) neurons with a sparse connectivity for homogeneous and heterogeneous in-degree distribution and the role of structural heterogeneity is analyzed.
Quantitative and qualitative analysis of asynchronous neural activity
The activity of a sparse network of leaky integrate-and-fire neurons is carefully revisited with reference to a regime of a bona-fide asynchronous dynamics, and the distribution of interspike intervals turns out to be relatively long-tailed; a crucial feature required for the self-sustainment of the bursting activity in a regime where neurons operate on average (much) below threshold.

The dynamics of networks of sparsely connected excitatory and inhibitory integrate-and-fire neurons are studied analytically. The analysis reveals a rich repertoire of states, including synchronous
Response Variability in Balanced Cortical Networks
The irregularity of spike trains is controlled mainly by the strength of the synapses relative to the difference between the firing threshold and the postfiring reset level of the membrane potential, and is very similar to those observed in primary visual cortex.
Collective irregular dynamics in balanced networks of leaky integrate-and-fire neurons
It is found that the neural network does not only exhibit a microscopic (single-neuron) stochastic-like evolution, but also a collective irregular dynamics (CID), which is a true thermodynamic phase, intrinsically different from the standard asynchronous regime.
Ubiquity of collective irregular dynamics in balanced networks of spiking neurons.
A detailed investigation of the thermodynamic limit for fixed density of connections (massive coupling) shows that, when inhibition prevails, the asymptotic regime is not asynchronous but rather characterized by a self-sustained irregular, macroscopic (collective) dynamics.
Chaos in Neuronal Networks with Balanced Excitatory and Inhibitory Activity
The hypothesis that the temporal variability in the firing of a neuron results from an approximate balance between its excitatory and inhibitory inputs was investigated theoretically.
Balanced Networks of Spiking Neurons with Spatially Dependent Recurrent Connections
The analysis of balanced networks is extended to include the known dependence of connection probability on the spatial separation between neurons, and it is derived that stable, balanced firing rate solutions require that the spatial spread of external inputs be broader than that of recurrent excitation.
