Erratum: Reversal of Diminished Inhibitory Sensory Gating in Cocaine Addicts by a Nicotinic Cholinergic Mechanism

In the paper, Adler LE, et al., Reversal of Diminished Inhibitory Sensory Gating in Cocaine Addicts by a Nicotinic Cholinergic Mechanism. Neuropsychopharmacology 24:671–679, 2001, Figure 1 and Figure 2 are incorrect. Figures 1 and 2 corresponded to text references to Figure 1. Figures 3 and 4 are to replace the previous text references to Figure 2.

Figure 1

Comparison of the ratio of test to conditioning amplitudes (TC ratio) for normals (n = 10, from Griffith et al. 1995) and the cocaine addicts (n = 11 day 1, n = 10 day 2). For TC ratio day 1, Student's t test: t = 3.82, df 19, p < .001 (Bonferroni corrected p < .01, ^** in graph). For TC ratio day 2, Student's test: t = 2.44, df 18, p < .05 (^* in graph); not significant by Bonferroni correction: p = .06). Error bars are standard deviation.

Figure 2

Comparison of the conditioning amplitude (CAMP) and test amplitude (TAMP) between normal subjects (n = 10, Griffith et al. 1995) and the cocaine addicts (n = 11 day 1, n = 10 day 2). For CAMP, day 1, Student's t-test: t = 3.26, df 19, p < .001 (Bonferroni corrected p = .008, ^** on graph). For CAMP, day 2, Student's t-test: t = 2.85, df 18, p < .01 (^** on graph), (Bonferroni corrected p = .06, not significant). Error bars are standard deviation.

Here are the correct Figures 1 and 2 with their respective legends.
