Amphetamine-type central nervous system stimulants release norepinephrine more potently than they release dopamine and serotonin.
A large body of evidence supports the hypothesis that mesolimbic dopamine (DA) mediates, in animal models, the reinforcing effects of central nervous system stimulants such as cocaine and amphetamine. The role DA plays in mediating amphetamine-type subjective effects of stimulants in humans remains to be established. Both amphetamine and cocaine increase norepinephrine (NE) via stimulation of r...
متن کاملDopamine, serotonin and impulsivity
Impulsive people have a strong urge to act without thinking. It is sometimes regarded as a positive trait but rash impulsiveness is also widely present in clinical disorders such as attention deficit hyperactivity disorder (ADHD), drug dependence, mania, and antisocial behaviour. Contemporary research has begun to make major inroads into unravelling the brain mechanisms underlying impulsive beh...
متن کاملDopamine release during human emotional processing
Involvement of dopamine neurotransmission in human emotional processing is unclear but animal studies have indicated that it is critical for processing of fear response. In this experiment we examined dopaminergic involvement in the processing of human emotions. We used a novel dynamic molecular imaging technique to detect and map dopamine released during presentation of emotional stimuli. The ...
متن کاملBrain serotonin and dopamine modulators, perceptual responses and endurance performance during exercise in the heat following creatine supplementation
BACKGROUND The present experiment examined the responses of peripheral modulators and indices of brain serotonin (5-HT) and dopamine (DA) function and their association with perception of effort during prolonged exercise in the heat after creatine (Cr) supplementation. METHODS Twenty one endurance-trained males performed, in a double-blind fashion, two constant-load exercise tests to exhausti...
متن کاملCaffeine induces dopamine and glutamate release in the shell of the nucleus accumbens.
An increase in the extracellular concentration of dopamine in the nucleus accumbens (NAc) is believed to be one of the main mechanisms involved in the rewarding and motor-activating properties of psychostimulants such as amphetamines and cocaine. Using in vivo microdialysis in freely moving rats, we demonstrate that systemic administration of behaviorally relevant doses of caffeine can preferen...
