Relapse to cocaine-seeking involves impairments in plasticity at glutamatergic synapses in the nucleus accumbens. Integrins are cell adhesion molecules that bind to the extracellular matrix and regulate aspects of synaptic plasticity, including glutamate receptor trafficking. To determine a role for integrins in cocaine-seeking, rats were trained to self-administer cocaine, the operant response...
Claims for the effectiveness of treatment for drug and alcohol problems differ dramatically. A recent overview of alcoholism-treatment outcome studies documented widely differing claims, ranging from a better than 90% recovery rate reported by a free-standing hospital facility to a 7% abstinence rate reported by the Rand Corporation for U.S. federally funded facilities.(1) What accounts for suc...
OBJECTIVES We examined the longitudinal effect of schools' drug policies on student marijuana use. METHODS We used data from the International Youth Development Study, which surveyed state-representative samples of students from Victoria, Australia, and Washington State. In wave 1 (2002), students in grades 7 and 9 (n = 3264) and a school administrator from each participating school (n = 188)...
Perineuronal nets (PNNs) are aggregates of extracellular matrix that form structures surrounding a subset of GABAergic interneurons. The staining intensity of PNNs appears to be related to plasticity. Environmental enrichment (EE) influences plasticity during adulthood: EE decreases the rewarding effects of drugs of abuse and diminishes both drug- and sucrose-seeking behavior. We determined the...
Smoking cessation is a process that unfolds over time and is characterized by intermittent lapses. We used parametric recurrent event survival analyses to better understand the dynamic relationship between a set of Abstinence Violation Effect (AVE, Marlatt & Gordon, 1985) responses to lapsing and subsequent lapse-relapse progression. Participants were 203 smokers who achieved abstinence and res...
Alcohol and nicotine addiction are frequently co-morbid and share common genetic factors and molecular mechanisms, such as the involvement of the nicotinic acetylcholine receptors [1]. Epidemiological studies show that the consumption of alcohol can influence the consumption of nicotine, and vice versa, indicating that interactions between alcohol and nicotine use are important in their co-abus...
In standard drug self-administration settings, animals have no choice than drug use. As a result, serious doubt exists about the interpretation of drug use in experimental animals. Is it symptomatic of an underlying addiction state or merely an expectable response to lack of choice? This incertitude in turn casts a shadow over many behavioral and neurobiological changes that have been well docu...
Ibogaine is an indole alkaloid found in the roots of Tabernanthe Iboga (Apocynaceae family), a rain forest shrub that is native to western Africa. Ibogaine is used by indigenous peoples in low doses to combat fatigue, hunger and thirst, and in higher doses as a sacrament in religious rituals. Members of American and European addict self-help groups have claimed that ibogaine promotes long-term ...
