Fig. 4From: Behavioral characterization of early nicotine withdrawal in the mouse: a potential model of acute dependenceSomatic withdrawal signs. A Illustration of the somatic withdrawal sign examination. B The number of paw tremors was significantly increased after early precipitated withdrawal (PW) from nicotine (asterisks). C The total number of somatic signs was significantly increased after PW and early spontaneous withdrawal (SW) from nicotine (asterisks). The total number of somatic signs was significantly different from the hypothetical value 2 after SW and PW (crosses). Data represent the mean ± S.E.M. from 10–11 mice/groupBack to article page
