this review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms. several studies have established that morp...

BACKGROUND Interindividual variability in the processing of reward might be partially explained by genetic differences in the dopamine system. Here, we study whether brain responses (event-related potentials [ERPs], oscillatory activity) to monetary gains and losses in normal human subjects are modulated as a function of two dopaminergic polymorphisms (catechol-O-methyltransferase [COMT] valine...

Near-miss events are situations in which an action yields a negative result but is very close to being successful. They are known to influence behavior, especially in gambling scenarios. Previous neuroimaging studies have described an anomalous activity of brain reward areas following these events. The goal of the present research was to study electrophysiological correlates of near-misses in t...

introduction: activation of n-methyl-d-aspartate (nmda) glutamate receptors in the nucleus accumbens is a component of drug-induced reward mechanism. in addition, nmda receptors play a major role in brain reward system and activation of these receptors can change firing pattern of dopamine neurons. blockade of glutamatergic neurotransmission reduces the expression of conditioned place preferenc...

this study was aimed at investigating the impact of organizational factors, leadership style, reward system and job design on psychological empowerment and its dimensions. this study was also aimed at measuring the level of employees' psychological empowerment. applied research method was survey-correlation using questionnaire as the measurement tool. statistical population included all em...

Subjective preferences affect many processes, including motivation, along with individual differences. Although incentive motivations are proposed to increase our limited visual working memory (VWM) capacity, much less is known about the effects of subjective preferences on VWM-related brain systems, such as the prefrontal and parietal cortices. Here, we investigate the differences in VWM capac...

Near-miss events are situations in which an action yields a negative result but is very close to being successful. They are known to influence behavior, especially in gambling scenarios. Previous neuroimaging studies have described an 'anomalous' activity of brain reward areas following these events. The goal of the present research was to study electrophysiological correlates of near-misses in...
