Electrical properties of cortical neurons in culture

Pyramidal morphology	Membrane potential (mV)	Input resistance (GΩ)
Control (13)	−63.4  ± 1.3	0.97  ± 0.05
TTX (14)	−63.6  ± 0.8	1.02  ± 0.02
TTX + BDNF (10)	−62.4  ± 1.5	0.99  ± 0.06
Bipolar morphology
Control (11)	−62.6  ± 1.1	1.11  ± 0.05
TTX (11)	−60.9  ± 1.5	1.19  ± 0.07

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.
