DTT effect on absolute sAHP amplitude from young and aged rats

		Holding current, nA
	sAHP amplitude, mV	Range	Mean ± SE
Young Control (n = 12)	4.23 ± 0.17	−0.8 to +0.4	−0.183 ± 0.114
Young DTT (n = 3)	4.38 ± 0.15	−0.2 to +0.1	−0.067 ± 0.088
Aged Control (n = 40)	6.44 ± 0.32	−0.7 to +0.7	−0.083 ± 0.051
Aged DTT (n = 5)	3.70 ± 0.78	−0.2 to +0.2	0.032 ± 0.078

The values for sAHP amplitude are indicated as mean ± S.E. The number in parentheses indicates the number of cells from the young and aged animals. The values of the holding. currents are presented as range and mean ± S.E.
