Analyses of Current Voltage and Conductance Voltage Relationships

	V_0.5	G_max	V_rev	k
	mV	nS	mV	mV/e-fold
Control	−16.76 ± 0.58	1.29 ± 0.06	67.27 ± 1.92	3.77 ± 0.43
Cocaine	−20.44 ± 0.35	2.57 ± 0.08	67.40 ± 1.41	3.76 ± 0.36

V _0.5 is the potential of half-maximal activation,G _max is the maximum wholecell conductance, V _rev is the reversal potential for the Ca²⁺ current, and k is the steepness factor.
