Assessment of reduction in stimulus generalization of ethanol-seeking during recovery: A rapid procedure
Previously, we developed a procedure which showed that longer histories of reinforced alternative behavior decrease the risk of relapse caused by a range of stimuli which had previously occasioned drinking. The decrease in relapse risk was likely due to a decrease in attention to the stimuli over the course of repeated engagement in the alternative behavior. However, this previous procedure was time consuming and did not mirror the procedure we used to observe changes in relapse risk. This study aimed at replicating the previous relationship between the duration of engaging in an alternative behavior and shift in stimulus generalization for drinking using a procedure that allows longitudinal analysis over time and is consistent with other procedures we have developed. Rats were trained to respond for ethanol in the presence of one stimulus (16 kHz tone; food Fixed Ratio (FR)150 and ethanol FR5), and for food in the under another stimulus (8 kHz tone; food and ethanol FR5). Then, recovery-like sessions with food predominant responding occurred in the presence of only the low-cost food stimulus. During these sessions, rats were exposed to non-reinforced graded stimuli alternation from 8 to 16 kHz alternating with the reinforced low-cost food stimulus. The number of responses on each (food and ethanol) lever before completing 5 responses on either lever was the main measure. Consistent with the earlier procedure, the current procedure showed that graded variation of tone from 8 to 16 kHz produced a graded increase in responding for ethanol compared to responding for food. In addition, longer periods of engaging in recovery-like responding shift the generalization function downwards. This procedure confirms the earlier pattern of stimulus generalization over longer periods of behavior consistent with recovery. This strengthens our hypothesis that shifts in attention to alcohol-related stimuli are important to the development of relapse resistance during recovery.
期刊介绍:
Alcohol is an international, peer-reviewed journal that is devoted to publishing multi-disciplinary biomedical research on all aspects of the actions or effects of alcohol on the nervous system or on other organ systems. Emphasis is given to studies into the causes and consequences of alcohol abuse and alcoholism, and biomedical aspects of diagnosis, etiology, treatment or prevention of alcohol-related health effects.
Intended for both research scientists and practicing clinicians, the journal publishes original research on the neurobiological, neurobehavioral, and pathophysiological processes associated with alcohol drinking, alcohol abuse, alcohol-seeking behavior, tolerance, dependence, withdrawal, protracted abstinence, and relapse. In addition, the journal reports studies on the effects alcohol on brain mechanisms of neuroplasticity over the life span, biological factors associated with adolescent alcohol abuse, pharmacotherapeutic strategies in the treatment of alcoholism, biological and biochemical markers of alcohol abuse and alcoholism, pathological effects of uncontrolled drinking, biomedical and molecular factors in the effects on liver, immune system, and other organ systems, and biomedical aspects of fetal alcohol spectrum disorder including mechanisms of damage, diagnosis and early detection, treatment, and prevention. Articles are published from all levels of biomedical inquiry, including the following: molecular and cellular studies of alcohol''s actions in vitro and in vivo; animal model studies of genetic, pharmacological, behavioral, developmental or pathophysiological aspects of alcohol; human studies of genetic, behavioral, cognitive, neuroimaging, or pathological aspects of alcohol drinking; clinical studies of diagnosis (including dual diagnosis), treatment, prevention, and epidemiology. The journal will publish 9 issues per year; the accepted abbreviation for Alcohol for bibliographic citation is Alcohol.
