Experimental and theoretical studies suggest that cortical networks are chaotic and coding relies on averages over large populations. However, there is evidence that rats can respond to the short stimulation of a single cortical cell, a theoretically unexplained fact. We study effects of single-cell stimulation on a large recurrent network of integrate-and-fire neurons and propose a simple way to detect the perturbation. Detection rates obtained from simulations and analytical estimates are…

Detecting single-cell stimulation in a large network of integrate-and-fire neurons.
A readout network with both feed-forward and local recurrent inhibition permits detection with a very small bias, if compared to the readout scheme introduced previously, and is robust if recurrent excitatory connections are included or if a different kind of readout bias is used.
Evoking prescribed spike times in stochastic neurons.
This work presents a method to determine a cell-specific stimulus that reliably evokes a prescribed spike train with high temporal precision of action potentials and test the performance of this stimulus in simulations for two different stochastic neuron models.
A network model of the barrel cortex combined with a differentiator detector reproduces features of the behavioral response to single-neuron stimulation
A large network of integrate-and-fire neurons with several salient features of neuronal populations in the rat barrel cortex is proposed and studied, demonstrating a possible mechanism for how the stimulation of a single neuron translates into a signal at the population level, which is taken as a proxy of the animal’s response.
How many neurons are sufficient for perception of cortical activity?
A steep sigmoidal relationship between the number of activated neurons and behaviour is found, saturating at only ~37 neurons, and this supports the sparse coding hypothesis, and suggests that cortical perception balances a trade-off between minimizing the impact of noise while efficiently detecting relevant signals.
Control of criticality and computation in spiking neuromorphic networks with plasticity
A relation between criticality, task-performance and information theoretic fingerprint in a spiking neuromorphic network with synaptic plasticity is demonstrated, and an understanding of how the collective network state should be tuned to task requirement is provided.
Receiver operating characteristic curves for a simple stochastic process that carries a static signal.
The results demonstrate that the sampling approximation provides a reasonable description of the ROC curve for this system, and it clarifies limit cases for the R OC curve.
Coding of low-dimensional variables with spiking neural networks


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.
Self-sustained activity in a small-world network of excitable neurons.
The dynamics of excitable integrate-and-fire neurons in a small-world network is studied, finding thatceedingly long transients emerge at higher densities p; their activity patterns are disordered, in contrast to the mostly periodic persistent patterns observed at low p.
Firing-rate response of a neuron receiving excitatory and inhibitory synaptic shot noise.
The shot-noise description of the neuronal response to synaptic dynamics is shown to be richer and qualitatively distinct from that predicted by the diffusion approximation and can be generalized to multiplicative shot noise so as to better capture effects of the inhibitory reversal potential.
Slow fluctuations in recurrent networks of spiking neurons.
A transition is found in the long-term variability of a sparse recurrent network of perfect integrate-and-fire neurons at which the Fano factor switches from zero to infinity and the correlation time is minimized, corresponding to a bifurcation in a linear map arising from the self-consistency of temporal input and output statistics.

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
Chaotic Balanced State in a Model of Cortical Circuits
The chaotic nature of the balanced state of this network model is revealed by showing that the evolution of the microscopic state of the network is extremely sensitive to small deviations in its initial conditions.
Two types of asynchronous activity in networks of excitatory and inhibitory spiking neurons
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.
Dynamical entropy production in spiking neuron networks in the balanced state.
A strikingly high rate of entropy production is found that would limit information representation in cortical spike patterns to the immediate stimulus response in inhibitory networks.
Comparative study of different integrate-and-fire neurons: spontaneous activity, dynamical response, and stimulus-induced correlation.
This work presents results on the white-noise-driven perfect, leaky, and quadratic IF models, focusing on the spectral statistics in different dynamical regimes ( noise-induced and tonic firing regimes with low or moderate noise).
Optimal heterogeneity for coding in spiking neural networks.
Heterogeneity decreases the threshold for synchronization, and its strength is nonlinearly related to the network mean firing rate, and conditions are shown under which heterogeneity optimizes network information transmission for either temporal or rate coding.
