Apr 10 2018 IV ethanol self administration has been reliably demonstrated in mouse and human experimental models however models of IV self administration have been historically problematic in the rat. An operant multiple schedule study design was used to elucidate the role of each component of a compound IV ethanol plus oral sucrose reinforcer.
Apr 03 2020 In the short access intravenous cocaine self administration model the TA 1 agonist RO reduced cocaine intake in rats Revel Moreau et al. 2012 . However although these studies indicated a critical role of TA 1 in regulating cocaine use disorder more studies are in need to examine the translational values of TA 1 agonists in more
IV nicotine self administration in rats using a consummatory operant licking response Sensitivity to serotonergic glutaminergic and histaminergic drugs By Vanessa Cousins Jed E. Rose and Edward D. Levin
aim was to evaluate a new procedure for nicotine self admin istration in rats using infusion doses and durations that would more closely mimic the kinetics of nicotine delivery in human cigarette smokers. Third we sought to determine the effects of dopamine DA D 1 and D 2 receptor antagonists on nicotine self administration. Here we
Rats were extinguished from nicotine self administration followed by subchronic NAC administration 0 or 100 mg/kg/d for 4 days prior to cue induced reinstatement. NAcore synaptic potentiation was measured via dendritic spine morphology and mRNA and protein of relevant glutamatergic genes were quantified.
Caffeine is the most commonly consumed psychoactive substance yet its potential reinforcing properties have been understudied. This study examined the impact of caffeine administration and expectancy on coffee related craving withdrawal and cue reactivity via a balanced placebo design. Following 18 h caffeine abstinence 65 daily coffee consumers 54 male received
Aug 01 2014 Acquisition of METH self administration using FR schedules of reinforcement The initial 20 days of training The total number of days for all rats to reach the criterion of stability on the FR1 and FR3 schedules of reinforcement was 9 and 11 days respectively.Fisher s exact tests were used to determine if there were differences between the PN and PS offspring

May 30 2006 Two strains of mice C57BL/6J B6 and DBA/2J D2 were allowed to self‐administer intravenous iv ethanol. These two strains were selected because they differ greatly in their preference for drinking ethanol solutions 86 mice are preferrers whereas D2 mice are avoiders of ethanol.

Apr 01 2005 If this assumption is correct a preclinical model should be able to take an abused drug and use it to shape and maintain a behavior. The drug self administration task provides support for this assumption and is arguably the most face valid model of human drug taking. In this task rats are surgically prepared with an intravenous IV catheter.
Drug self administration procedures have played a critical role in the experimental analysis of psychoactive compounds such as cocaine for over 50 years. While there are numerous permutations of this procedure this paper will specifically focus on choice procedures using concurrent schedules of intravenous drug self administration. The aims of this paper are to
Previously we found that sazetidine A Saz A which selectively desensitizes α4β2 nicotinic receptors significantly decreased intravenous IV nicotine self administration SA in rats with an effective dose of 3 mg/kg in acute and repeated injection studies.
Oct 29 2020 The other 46 rats were trained by limited n = 9 for saline and n = 14 for cocaine or extended n = 10 for saline and n = 13 for cocaine IVSA procedures and whole cell patch clamp recordings were obtained either 1 or 45 days after the last IVSA session. 2.2 Intravenous self administration of cocaine 2.2.1 Catheter implantation
Aug 28 2020 8 lever press for intravenous nicotine 0.03 mg/kg/inf followed by access to sucrose 30 s later. After 1 3 9 and 9 20 nicotine sucrose training sessions appetitive learning in the form of a goal tracking response was assessed 10 using a non contingent nicotine alone test. All rats acquired nicotine self administration and learned to
Jan 05 2012 Effect of access to nicotine self administration. Rats trained in the IVSA paradigm treated with test compounds 1–7 at 15 mg/kg i.p. showed decreases in nicotine self administration ranging from 14 to 33 Table 1 .Certain compounds i.e. 2 5 and 6 tested in rats at 25 mg/kg showed decreases in nicotine self administration ranging from 60 to

The present study examined instead the impact of a motivationally neutral cue on self administration. Methods Adult male Long Evans rats were permitted to self administer nicotine 0.015 mg/kg IV given over 30 s 2 h/day or saline presented with or without a sensory stimulus light white noise .
This study compared the latency and proportion to acquire self administration maintenance of self administration and within session response patterns. Methods. Rats were given extended access 8 hour daily sessions to either methamphetamine MDMA or vehicle self administration over a period of 10 consecutive days.
Self administration of remifentanil an ultra short acting opioid under continuous and progressive ratio schedules of reinforcement in rats. Journal Article In Psychopharmacology Berl 150 1 pp. 61–66 2000 ISSN 0033 3158 Print 0033 3158 Linking .
Apr 01 1999 The reinforcing properties of a variety of drugs abused by humans have been investigated using the technique of intravenous self administration in the rat. To examine the effect of nicotine dose on nicotine self administration Wistar rats were allowed to self administer various doses of nicotine using a within subjects Latin square design.
Dec 01 1989 Hanson et al. 1979 investigated nicotine self administration in free feeding rats but animals were treated chronically with IV nicotine for 2 days before self administration sessions began. Nicotine intake was found to increase progressively over periods of weeks similarly extinction was a protracted process.
In a previous study of male and female smokers we examined self administration of IV nicotine using a choice procedure in which smokers were able to choose between three IV nicotine doses and saline.
caffeine self administration in rats. The self administration of caffeine was established and modified by a combination of behavioral and pharmacological factors including food restriction drug dose and infusion rate. The results suggest caffeine maintained behavior is comparable to nicotine self administration but distinct from that of
