Effects of extracellular calcium on the volley activity of entorhinal cortex neurons in neonatal rats: computer simulation.

M G Sheroziya1, A V Egorov.   

Abstract

The calcium-dependent volley activity of neurons in the entorhinal cortex of neonatal rats increased when the extracellular Ca(2+) concentration decreased from 2 to 1 mM. This may be associated with changes in the properties of the slow sodium current. Computer simulation of volley neurons using a model including a relationship between the slow sodium current and extracellular Ca(2+) supported this suggestion.
