Table 1.

Mean baseline thresholds (in μA) and response latencies (in sec) for experimental groups during Phases 1 and 2 of Experiment 3. Baseline data during Phase 2 are averaged across both osmotic minipump exposures for each group.

	Phase 1		Phase 2
	Threshold (μA)	Latency (sec)	Threshold (μA)	Latency (sec)
Group 1	79.4 ± 13.7	2.3 ± 0.2	88.3 ± 15.1	2.3 ± 0.1
Group 2	76.5 ± 3.7	2.5 ± 0.2	75.6 ± 3.1	2.4 ± 0.1
Group 3	82.3 ± 10.8	2.9 ± 0.2	72.4 ± 5.0	2.6 ± 0.2
