Spike-timing computation properties of a feed-forward neural network model

Drew B. Sinha, Noah M. Ledbetter, Dennis L. Barbour
2014 Frontiers in Computational Neuroscience  
When background activity was correlated or parallel disynaptic pathways were added, however, robust polysynaptic spike timing relationships were observed, and application of STS yielded predictable changes  ...  We investigated how activity varied when dynamics were perturbed by an activity-dependent electrical stimulation protocol (spike-triggered stimulation; STS) in networks of different topologies and background  ...  ACKNOWLEDGMENTS We would like to thank Jeffery Gamble, Ruiye Ni, Xinyu Song, and Wensheng Sun for helpful comments on early drafts of this manuscript.

On how correlations between excitatory and inhibitory synaptic inputs maximize the information rate of neuronal firing

Pavel A. Puzerey, Roberto F. Galán
2014 Frontiers in Computational Neuroscience  
Conversely, inhibition that is too delayed broadens neuronal integration times, thereby diminishing spike-time precision and increasing the firing frequency.  ...  Cortical neurons receive barrages of excitatory and inhibitory inputs which are not independent, as network structure and synaptic kinetics impose statistical correlations.  ...  long lags will likely decrease the precision of neuronal firing by prolonging the window of integration of presynaptic inputs.  ...
