  • Resting potentials and input resistances of pyramidal and bipolar neurons grown for 2 d under the different experimental conditions. Values were measured under conditions where synaptic transmission was blocked with CNQX and bicuculline. Values are mean ± SEM for the number of neurons indicated in parentheses.
