Impulsive Choice in Lewis and Fischer 344 Rats: Effects of Extended Training
Delay discounting in Lewis and Fischer 344 was compared using a novel concurrent-chains procedure. In the initial-link, two levers were available and a random-interval schedule was in effect. One terminal link provided a smaller reinforcer (1 pellet) and the other terminal provided a larger reinforcer (4 pellets). Terminal-link entry was scheduled randomly, with the constraint that entries to e...
متن کاملTeratogenic assessment of 2,4-dichlorophenol in Fischer 344 rats.
The potential maternal, embryotoxic, and teratogenic parameters of 2,4-dichlorophenol (2,4-DCP) were evaluated in Fischer 344 rats following oral administration in corn oil on Days 6 through 15 of gestation. Dose levels were 0, 200, 375, and 750 mg/kg/day. Females were sacrificed on Gestation Day 20 and cesarean sections performed. The fetuses were weighed, sexed, measured for crown-rump length...
متن کاملAssessment of the aversive effects of peripheral mu opioid receptor agonism in Fischer 344 and Lewis rats.
The Fischer 344 (F344) and Lewis (LEW) inbred rat strains differ on a host of biochemical, neuroanatomical, immunological and behavioral endpoints. One behavioral difference of interest is their differential reactivity to the aversive effects of morphine as indexed by the conditioned taste aversion preparation (aversions acquired by F344 rats are significantly greater than those acquired by the...
متن کاملSpontaneous withdrawal in opiate-dependent Fischer 344, Lewis and Sprague-Dawley rats.
The Lewis (LEW) and Fischer 344 (F344) inbred rat strains react differentially to acute morphine administration for a variety of behavioral and neurochemical measures. Investigations into effects of chronic morphine are less common, and investigations assessing dependence have been limited to those utilizing antagonist-precipitated withdrawal. The present experiment extended these assessments b...
متن کاملIsolating the delay component of impulsive choice in adolescent rats
Impulsive choice-the preference for small immediate rewards over larger delayed rewards-has been linked to various psychological conditions ranging from behavioral disorders to addiction. These links highlight the critical need to dissect the various components of this multifaceted behavioral trait. Delay discounting tasks allow researchers to study an important factor of this behavior: how the...
