Neural systems supporting interoceptive awareness
In right anterior insular/opercular cortex, neural activity predicted subjects' accuracy in the heartbeat detection task and local gray matter volume correlated with both interoceptive accuracy and subjective ratings of visceral awareness. Expand

It is hypothesized that the neural substrate for these processes during motivational and affective behavior lies within the interactions of anterior cingulate, insula, and orbitofrontal cortices. Expand
Human cingulate cortex and autonomic control: converging neuroimaging and clinical evidence.
Converging neuroimaging and clinical findings suggest that ACC function mediates context-driven modulation of bodily arousal states during effortful cognitive and motor behaviour. Expand
Temporal Difference Models and Reward-Related Learning in the Human Brain
Regression analyses revealed that responses in ventral striatum and orbitofrontal cortex were significantly correlated with this prediction error signal, suggesting that, during appetitive conditioning, computations described by temporal difference learning are expressed in the human brain. Expand
Regret and its avoidance: a neuroimaging study of choice behavior
It is demonstrated that medial orbitofrontal cortex modulates the gain of adaptive emotions in a manner that may provide a substrate for the influence of high-level emotions on decision making. Expand
Dissociating Valence of Outcome from Behavioral Control in Human Orbital and Ventral Prefrontal Cortices
Functional heterogeneity within the orbitofrontal cortex is suggested, with a role for this region in representing stimulus-reward values, signaling changes in reinforcement contingencies and in behavioral control. Expand
Beauty in a smile: the role of medial orbitofrontal cortex in facial attractiveness
Brain regions that respond to attractive faces which manifested either a neutral or mildly happy face expression were investigated, suggesting that the reward value of an attractive face as indexed by medial OFC activity is modulated by a perceiver directed smile. Expand
Explicit and implicit neural mechanisms for processing of social information from facial expressions: A functional magnetic resonance imaging study
The processing of changing nonverbal social signals such as facial expressions is poorly understood, and it is unknown if different pathways are activated during effortful (explicit), compared toExpand
Neural Activity in the Human Brain Relating to Uncertainty and Arousal during Anticipation
Brain activity during delay between reward-related decisions and their outcomes is measured to highlight distinct contributions of cognitive uncertainty and autonomic arousal to anticipatory neural activity in prefrontal cortex. Expand
Neural Activity Relating to Generation and Representation of Galvanic Skin Conductance Responses: A Functional Magnetic Resonance Imaging Study
The results suggest that areas implicated in emotion and attention are differentially involved in generation and representation of peripheral SCR responses, and propose that this functional arrangement enables integration of adaptive bodily responses with ongoing emotional and attentional states of the organism.
