B. DPSP amplitude, duration, and area

	Amplitude (mV)	Standard ACSF duration (msec)	Area
Control	12.6 ± 1.1 (n = 28)^2_a	12.1 ± 0.7	149 ± 13^2_b
Mutant	14.6 ± 0.9 (n = 29)	13.9 ± 1.1	189 ± 13
		Mg²⁺-free ACSF + CNQX
Control	11.5 ± 1.3 (n = 21)	39.0 ± 3.6	494 ± 96
Mutant	11.7 ± 1.3 (n = 21)	49.4 ± 4.3	652 ± 118

↵F2_a Mean ± SE. Number for each group is in parentheses.
↵F2_b Difference between means for mutants and controls is statistically significantl (t = −2.11, df = 55,p = 0.0396).
