Basic membrane properties of PGA and non-PGA pyramidal neurons. Cell membrane capacitance (Cm), input resistance (Rm), and decay time constant (tau), were similar between both groups.

Cell Type	Cm (pA)	Rm (MΩ)	Tau (ms)
Normal-like (n=24)	160.5±14	158.2±23	2.6±0.2
Immature (n=4)	78.0±17	610±214	0.9±0.4
Cytomegalic (n=5)	449.5±54	65.8±28	4.6±0.6

Basic Membrane Properties of Non-PGA Pyramidal Neurons
	Cm (pA)	Rm (MΩ)	Tau (ms)
