Dopamine neurons of the ventral tegmental area (VTA) signal the occurrence of a reward-predicting conditioned stimulus (CS) with a subsecond duration increase in post-CS firing rate. Important theories about reward-prediction error and reward expectancy have been informed by the substantial number of studies that have examined post-CS phasic VTA neuron activity. On the other hand, the role of V...

Wastage of perishable and non-perishable products due to manual monitoring in shopping malls creates huge revenue loss supermarket industry. Besides, internal external factors such as calendar events weather condition contribute excess wastage different regions supermarket. It is a challenging job know about the manually supermarkets region-wise. Therefore, management needs take appropriate dec...

Conventional neuroimaging techniques provide information about condition-related changes of the BOLD (blood-oxygen-level dependent) signal, indicating only where and when the underlying cognitive processes occur. Recently, with the help of a new approach called "model-based" functional neuroimaging (fMRI), researchers are able to visualize changes in the internal variables of a time varying lea...

The mesolimbic dopamine (DA) system plays an integral role in incentive motivation and reward seeking and a growing body of evidence identifies signal transduction at cannabinoid receptors as a critical modulator of this system. Indeed, administration of exogenous cannabinoids results in burst firing of DA neurons of the ventral tegmental area and increases extracellular DA in the nucleus accum...

Dishonest acts are all too prevalent in day-to-day life. This article examines some possible psychological causes for dishonesty that go beyond the standard economic considerations of probability and value of external payoffs. The authors propose a general model of dishonest behavior that includes internal psychological reward mechanisms for honesty and dishonesty, and they discuss the implicat...
