Although recreational drug use by human adolescents is a well-known and long-standing problem, relatively little is known regarding differences in behavioral and physiological responses to abused substances in adolescent vs adult animals. The present study compared effects of the psychomotor stimulant, cocaine, in periadolescent (postnatal days 37-52) and(More)
Despite increasing rates of opioid abuse by human adolescents, few laboratory experiments address adolescent vulnerability to opiates. We examined intravenous morphine self-administration after adolescent- vs. adult-onset, followed by extinction and cue-induced reinstatement. Adolescent male Sprague-Dawley rats [postnatal day (P) 35 at start] and adults(More)
Although onset of drug use during adolescence appears to increase long-term vulnerability to drug dependence in humans, relatively little is known about extinction and reinstatement of drug seeking after periadolescent onset of drug self-administration in laboratory animals. Furthermore, although cue-induced reinstatement of cocaine seeking increases(More)
Recreational drug use peaks in the developmental stage of adolescence, and exposure to drugs during adolescence may predict drug dependence in adulthood. Nevertheless, adolescent drug vulnerability is not widely studied in animal models of drug intake, and very few studies have investigated sex differences in drug-related behavior during adolescence. We(More)
Previously we reported that time-dependent increases in cue-induced reinstatement of cocaine seeking were attenuated in rats self-administering cocaine as adolescents, compared with adults (Li and Frantz (2009)). Now using sucrose self-administration, we report time-dependent increases in cue-induced reinstatement of sucrose seeking are similar across age(More)
Undergraduate students may be attracted to science and retained in science by engaging in laboratory research. Experience as an apprentice in a scientist's laboratory can be effective in this regard, but the pool of willing scientists is sometimes limited and sustained contact between students and faculty is sometimes minimal. We report outcomes from two(More)
Are we neuroscientists doing our part to help revive science education, to stimulate teachers' ingenuity, and diversify the intellectual capital among the next generation of scientists? Certainly we support progressive initiatives, including a major international Brain Awareness Campaign, local chapter grants for Society for Neuro-science (SfN) members, and(More)
Early onset of heroin use during adolescence might increase chances of later drug addiction. Prior work from our laboratory suggests, however, that adolescent male rats are actually less sensitive than adults to some enduring effects of heroin self-administration. In the present study, we tested two likely correlates of sensitivity to behavioral(More)
Adolescent drug abuse is hypothesized to increase the risk of drug addiction. Yet male rats that self-administer heroin as adolescents show attenuated drug-seeking after abstinence, compared with adults. Here we explore a role for neural activity in the medial prefrontal cortex (mPFC) in age-dependent heroin-seeking. Adolescent (35-day-old at start;(More)
Brains Rule! Neuroscience Expositions, funded through a National Institute on Drug Abuse Science Education Drug Abuse Partnership Award, has developed a successful model for informal neuroscience education. Each Exposition is a "reverse science fair" in which neuroscientists present short neuroscience teaching modules to students. This study focuses on(More)
