'Balancing' of Conductances May Explain Irregular Cortical Spiking
Five related factors are identified which enable single compartment Hodgkin-Huxley model neurons to convert random synaptic input into irregular spike trains similar to those seen in in vivo cortical recordings. We suggest that cortical neurons may operate in a narrow parameter regime where synaptic and intrinsic conductances are balanced to reflect, through spike timing, detailed correlations in the inputs.
