ERRATUM
In the article "Leptin Attenuates Acute Food
Deprivation-Induced Relapse to Heroin Seeking," by Uri Shalev,
Jasmine Yap, and Yavin Shaham, which was originally published online as
a Rapid Communication (RC129) on February 5, 2001, a printer's error
caused several of the authors' proof corrections to be removed from
the article. The corrections are as follows: The title to Table 1 should be "Lever-pressing behavior during the training and extinction phases." In the first paragraph of Materials and Methods, one of the
suppliers mentioned, Med Associates, is actually located in Georgia,
VT. The first sentence of the second paragraph of Results should read
"Because of skewed distributions, a square-root transformation (Cohen
and Cohen, 1983) was used before conducting the repeated measures ANOVA
with leptin dose (0, 2, or 4 µg) as the between-subjects factor and
food deprivation (food deprived and food sated) as the within-subjects
factor." The last sentence of this same paragraph should read
"Leptin also decreased body weight gain when food was reintroduced
after 1 d of deprivation (vehicle group, 20.6 ± 3.7 gm per day; leptin
groups, 7.2 ± 2.3; p < 0.01) but had no effect on body
weight loss induced by food deprivation (vehicle group, 22.2 ± 7.7 gm
per day; leptin groups, 26.4 ± 2.1; p > 0.5)." The
second sentence of the second paragraph of Results should read "The
repeated measures ANOVA using leptin dose (0, 2, or 4 µg) as the
between-subjects factor and test condition (saline priming, heroin
priming, and footshock) as the within-subjects factor revealed
significant effects of test condition on responses on the previously
active lever (F(2,36) =12.2; p < 0.01) (Fig. 2A) and on the inactive lever
(F(2,36) = 3.2; p < 0.05) (Fig. 2B)." In the third and fifth paragraphs of the Discussion,
"CeA" should be changed to "amygdala." In the last sentence of
the fourth paragraph of the Discussion, "c-fos" should not be
italicized. The second sentence of the fifth paragraph of the
Discussion should read "Acute (24-48 hr) food deprivation increases
CRF (Heinrichs and Richard, 1999) and NA (Stanley et al., 1989)
utilization in the hypothalamus, a region that receives its major NA
input from the lateral tegmental NA nuclei via the ventral NA bundle
(Moore and Bloom, 1979; Pacak et al., 1998)." The fourth sentence of this same paragraph should read "The effect of acute food deprivation on extrahypothalamic CRF and NA has not been studied, but these systems
also might be activated by this deprivation condition." The heading
of the last paragraph of the Discussion should read "Concluding
remarks," and the last sentence of this final paragraph should read
"Thus, medications that target the central leptin system and/or other
hypothalamic hormones that are regulated by leptin (Ahima et al., 2000)
may be considered for the treatment of drug addicts with comorbid
eating disorders." These corrections are reflected in the online text
that appears at
