Reward activates stimulus-specific and task-dependent representations in visual association cortices

AM Schiffer, T Muller, N Yeung… - Journal of …, 2014 - Soc Neuroscience
Humans reliably learn which actions lead to rewards. One prominent question is how credit
is assigned to environmental stimuli that are acted upon. Recent functional magnetic …

Learning to like: a role for human orbitofrontal cortex in conditioned reward

SML Cox, A Andrade, IS Johnsrude - Journal of Neuroscience, 2005 - Soc Neuroscience
A great deal of human behavior and motivation is based on the intrinsic emotional
significance of rewarding or aversive events, as well as on the associations formed between …

Using fMRI to study reward processing in humans: past, present, and future

KS Wang, DV Smith… - Journal of …, 2016 - journals.physiology.org
Functional magnetic resonance imaging (fMRI) is a noninvasive tool used to probe cognitive
and affective processes. Although fMRI provides indirect measures of neural activity, the …

Ventral midbrain stimulation induces perceptual learning and cortical plasticity in primates

JT Arsenault, W Vanduffel - Nature communications, 2019 - nature.com

[PDF][PDF] Dopamine-induced dissociation of BOLD and neural activity in macaque visual cortex

D Zaldivar, A Rauch, K Whittingstall, NK Logothetis… - Current Biology, 2014 - cell.com
Neuromodulators determine how neural circuits process information during cognitive states
such as wakefulness, attention, learning, and memory [1]. fMRI can provide insight into their …

Subregions of the ventral striatum show preferential coding of reward magnitude and probability

J Yacubian, T Sommer, K Schroeder, J Gläscher… - Neuroimage, 2007 - Elsevier
As shown in non-human primate and human fMRI studies the probability and magnitude of
anticipated rewards modulate activity in the mesolimbic dopaminergic system. Importantly …
