Altered attention to alcohol-related cues is implicated in the craving and relapse cycle characteristic of alcohol dependence (ALC). Prior cue reactivity studies typically invoke explicit attention to alcohol cues, so the neural response underlying incidental cue exposure remains unclear. Here, we embed infrequent, task-irrelevant alcohol and non-alcohol(More)
BACKGROUND Evidence suggests that the transition from experimental to regular smoking is facilitated by the influence of tobacco on affective and attentional mechanisms. The objective of this study was to examine affective and attentional responses in young adult smokers using fear-potentiated startle and prepulse inhibition. METHODS Participants were 56(More)
Inhibition is a key executive function in adults and children for the acquisition and expression of cognitive abilities. Using event-related potentials in a priming adaptation of a Piaget-like numerical task taken from developmental psychology, we report a negative priming effect in adults measured just after the cognitive inhibition of a misleading(More)
One of the primary limitations of many psychiatric medications is weight gain, the mechanism of which remains to be fully elucidated. We conducted a 2-week double-blind placebo-controlled study on weight gain with olanzapine, which is frequently but unpredictably associated with this side effect, to address the possible mechanisms of weight gain independent(More)
Hyperactive intracellular calcium ion (Ca) signaling in peripheral cells has been a reliable finding in bipolar disorder. Some established mood stabilizing medications, such as lithium and carbamazepine, have been found to normalize elevated intracellular Ca concentrations ([Ca]i) in platelets and lymphocytes from bipolar disorder patients, and some(More)
vértice, que se desarrolla entre dos estímulos sucesivos relacionados con la tarea [4]. La nicotina/el fumar afectan a la amplitud de la VNC en una manera bifási-ca dependiente de la dosis y parecen producir efectos tanto estimulantes como depresores sobre la función cerebral [1, 8]. Los informes de diferencias de género en la sensibi-lidad a la nicotina/el(More)
Studies on the enhancing effects of nicotine on performance are usually pharmacological challenges using deprived male smokers. However, gender may be a factor that influences nicotine/smoking effects upon information processing. We investigated gender differences in contingent negative variation (CNV) amplitude in non-deprived dependent smokers performing(More)
