Effects of Pair-Wise and Higher Order Correlations on the Firing Rate of a Post-211 Synaptic Neuron. Software Engineering

摘要

Coincident firing of neurons projecting to a common target cell is likely to211u001eraise the probability of firing of this post-synaptic cell. Therefore 211u001esynchronized firing constitutes a significant event for post-synaptic neurons and 211u001eis likely to play a role in neuronal information processing. Physiological data 211u001eon synchronized firing in cortical networks is primarily based on paired 211u001erecordings and cross-correlation analysis. However, pair-wise correlations among 211u001eall inputs onto a post-synaptic neuron do not uniquely determine the distribution 211u001eof simultaneous post-synaptic events. We develop a framework in order to 211u001ecalculate the amount of synchronous firing that, based on maximum entropy, should 211u001eexist in a homogeneous neural network in which the neurons have known pair-wise 211u001ecorrelations and higher order structure is absent.
