Summary of impedance measurements in dissociated Müller cells

Recording site	Condition of cell	Resistance (MΩ)	Time constant (ms)	Capacitance (pF)
Nuclear region	Intact	8.8 ± 0.7 (55)	0.95 ± 0.07 (40)	149 ± 17 (40)
	Cut	140 ± 16 (30)	12.5 ± 1.8 (29)	94 ± 7 (29)
	Ratio cut/intact	15.9	13.2	0.63
Endfoot	Intact	12.5 ± 2.5 (14)
	Cut	15.8 ± 2.9 (8)
	Ratio cut/intact	1.26

Values ± s.e. are given. The sample size is indicated in parentheses. Capacitance values are calculated from the relation: capacitance = τ/resistance. Time constants were not measured for endfoot penetrations.
