Anticipation of increasing monetary reward selectively recruits nucleus accumbens.
TLDR
Findings suggest that whereas other striatal areas may code for expected incentive magnitude, a region in the NAcc codes for expected positive incentive value, which is correlated with individual differences in self-reported happiness elicited by the reward cues.Abstract:
Comparative studies have implicated the nucleus accumbens (NAcc) in the anticipation of incentives, but the relative responsiveness of this neural substrate during anticipation of rewards versus punishments remains unclear. Using event-related functional magnetic resonance imaging, we investigated whether the anticipation of increasing monetary rewards and punishments would increase NAcc blood oxygen level-dependent contrast (hereafter, "activation") in eight healthy volunteers. Whereas anticipation of increasing rewards elicited both increasing self-reported happiness and NAcc activation, anticipation of increasing punishment elicited neither. However, anticipation of both rewards and punishments activated a different striatal region (the medial caudate). At the highest reward level ($5.00), NAcc activation was correlated with individual differences in self-reported happiness elicited by the reward cues. These findings suggest that whereas other striatal areas may code for expected incentive magnitude, a region in the NAcc codes for expected positive incentive value.read more

The reward circuit: linking primate anatomy and human imaging.

TL;DR: It is shown that human functional and structural imaging results map increasingly close to primate anatomy, and advances in neuroimaging techniques allow better spatial and temporal resolution.

The Adolescent Brain
TL;DR: Evidence is provided that there is a heightened responsiveness to incentives and socioemotional contexts during this time, when impulse control is still relatively immature, which suggests differential development of bottom‐up limbic systems to top‐down control systems during adolescence as compared to childhood and adulthood.

TL;DR: It is concluded that self-referential processing in CMS constitutes the core of the authors' self and is critical for elaborating experiential feelings of self, uniting several distinct concepts evident in current neuroscience.

Relative Income, Happiness and Utility: An Explanation for the Easterlin Paradox and Other Puzzles
TL;DR: In this article, the authors review the evidence on relative income from the subjective well-being literature and discuss the relation (or not) between happiness and utility, and discuss some nonhappiness research (behavioral, experimental, neurological) related to income comparisons.

A Neural Substrate of Prediction and Reward
TL;DR: Findings in this work indicate that dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events can be understood through quantitative theories of adaptive optimizing control.

What is the role of dopamine in reward: hedonic impact, reward learning, or incentive salience?
TL;DR: It is suggested that dopamine may be more important to incentive salience attributions to the neural representations of reward-related stimuli and is a distinct component of motivation and reward.
