Title:
"Membrane potential and response properties of populations of
cortical neurons in the high conductance state"


Authors:
Ruben Moreno-Bote and Nestor Parga

Abstract:

Because of intense synaptic activity, cortical neurons are in a high
conductance state. We show that this state has important consequences
on the properties of a population of independent model neurons with
conductance-based synapses. Using an adiabaticlike approximation we
study both the membrane potential and the firing probability
distributions across the population. We find that the latter is
bimodal in such a way that at any particular moment some neurons are
inactive while others are active. The population rate and the response
variability are also characterized.
