Does amygdala dysfunction attenuate frustration-induced aggression in psychopathic individuals in a non-criminal population?
The possibility that levels of psychopathic traits in a regular population were milder than in incarcerated populations cannot be ruled out.
Extending results of previous studies involving non-drug stimuli, the present study showed that extinguished cocaine cues can enhance cocaine seeking when compounded with other cocaine cues. These results illustrate the persistence of drug cues in controlling behavior despite extinction and highlight the need for developing treatments that eliminate this residual energizing capacity that survives extinction.
