Reward expectation differentially modulates attentional behavior and activity in visual area V4
2015
Nature Neuroscience
Preserved Fulltext
We trained monkeys to discriminate the orientation of two stimuli presented simultaneously in different hemifields while we independently varied the reward magnitude associated with correct discrimination ...
By contrast, neurons in V4 were consistently modulated by absolute reward value, exhibiting increased activity, increased gamma-band power and decreased trial-to-trial variability whenever receptive field ...

The triadic neural systems model is a heuristic tool, which was developed with the goal of providing a framework for neuroscience research into motivated behaviors. ...
A first application of this model has been to account for adolescent behavior. ...
This shift in social orientation is likely to originate from the interaction among all three maturing modules of the triadic model, in addition to a reorganization of the social neural circuitry (Blakemore ...

Similar contextual modulation occurs widely in the sensory system, and efficient coding principles derived in the sensory domain suggest a new framework for understanding the neural coding of value. ...
Although normative theories of choice have outlined the theoretical structure of these valuations, recent experiments have begun to reveal how value is instantiated in the activity of neurons and neural ...
Introduction The activity in many brain regions is sensitive to reward, a modulation that can reflect not just value but processes such as sensation, motivation, and attention. ...
