Correlation and Synchrony Transfer in Integrate-and-Fire Neurons:<? format?> Basic Properties and Consequences for Coding

E Shea-Brown, K Josić, J De La Rocha, B Doiron - Physical review letters, 2008 - APS
We study how pairs of neurons transfer correlated input currents into correlated spikes. Over
rapid time scales, correlation transfer increases with both spike time variability and rate; the …

Correlations and synchrony in threshold neuron models

T Tchumatchenko, A Malyshev, T Geisel, M Volgushev… - Physical review …, 2010 - APS
We study how threshold models and neocortical neurons transfer temporal and
interneuronal input correlations to correlations of spikes. In both, we find that the low …

Response of integrate-and-fire neurons to noisy inputs filtered by synapses with arbitrary timescales: Firing rate and correlations

R Moreno-Bote, N Parga - Neural Computation, 2010 - direct.mit.edu
Delivery of neurotransmitter produces on a synapse a current that flows through the
membrane and gets transmitted into the soma of the neuron, where it is integrated. The …
