Passive and active membrane properties of lamina II EGFP- and non-EGFP-expressing neurones

	EGFP-labelled neurones	Non-EGFP-labelled neurones
Voltage-clamp measurements were made with a patch-clamp amplifier, current-clamp mesurements were made with a microelectrode amplifier in bridge mode. Statistical significance of differences of EGFP-labelled neurones as compared to non-EGFP-labelled neurones is indicated by * (P < 0.05) and ** (P < 0.01). Numbers of observations indicated in parentheses.
Resting membrane potential (RMP, mV)	−62 ± 1 (106)	−61 ± 1 (91)
Membrane resistance (MΩ)	1051 ± 50 (109)	1224 ± 75 (79)
Membrane capacitance (pF)	50 ± 2 (109) **	37 ± 2 (79)
Action potential threshold (mV)	−35 ± 1 (110) **	−31 ± 1 (90)
Action potential threshold – RMP (mV)	27 ± 1 (104) *	30 ± 1 (90)
Action potential width at base (ms)	1.9 ± 0.1 (15)**	2.4 ± 0.1 (13)
Action potential height from base (mV)	77 ± 2 (15) **	63 ± 5 (13)
