Neuronal reward and decision signals: from theories to data
W Schultz - Physiological reviews, 2015 - journals.physiology.org
Rewards are crucial objects that induce learning, approach behavior, choices, and
emotions. Whereas emotions are difficult to investigate in animals, the learning function is …

What the orbitofrontal cortex does not do
TA Stalnaker, NK Cooch, G Schoenbaum - Nature neuroscience, 2015 - nature.com
The number of papers about the orbitofrontal cortex (OFC) has grown from 1 per month in
1987 to a current rate of over 50 per month. This publication stream has implicated the OFC …

[HTML][HTML] Orbitofrontal cortex uses distinct codes for different choice attributes in decisions motivated by curiosity
TC Blanchard, BY Hayden, ES Bromberg-Martin - Neuron, 2015 - cell.com
Decision makers are curious and consequently value advance information about future
events. We made use of this fact to test competing theories of value representation in area …

Reward value comparison via mutual inhibition in ventromedial prefrontal cortex
Recent theories suggest that reward-based choice reflects competition between value
signals in the ventromedial prefrontal cortex (vmPFC). We tested this idea by recording …

Dynamic salience processing in paraventricular thalamus gates associative learning
The salience of behaviorally relevant stimuli is dynamic and influenced by internal state and
external environment. Monitoring such changes is critical for effective learning and flexible …

An oxytocin-induced facilitation of neural and emotional responses to social touch correlates inversely with autism traits
D Scheele, KM Kendrick, C Khouri, E Kretzer… - …, 2014 - nature.com
Social communication through touch and mutual grooming can convey highly salient socio-
emotional signals and has been shown to involve the neuropeptide oxytocin (OXT) in …

Disentangling neural representations of value and salience in the human brain
A large body of evidence has implicated the posterior parietal and orbitofrontal cortex in the
processing of value. However, value correlates perfectly with salience when appetitive …

The dopamine prediction error: contributions to associative models of reward learning
HM Nasser, DJ Calu, G Schoenbaum… - Frontiers in …, 2017 - frontiersin.org
Phasic activity of midbrain dopamine neurons is currently thought to encapsulate the

Targeted stimulation of human orbitofrontal networks disrupts outcome-guided behavior
Outcome-guided behavior requires knowledge about the current value of expected
outcomes. Such behavior can be isolated in the reinforcer devaluation task, which assesses …

Dopamine error signal to actively cope with lack of expected reward
S Ishino, T Kamada, GA Sarpong, J Kitano… - Science …, 2023 - science.org
To obtain more of a particular uncertain reward, animals must learn to actively overcome the
lack of reward and adjust behavior to obtain it again. The neural mechanisms underlying …
