Partially overlapping neural networks for real and imagined hand movements.
Results suggest that a specific neuronal substrate is involved in the processing of hand motor representations in the form of cortico-subcortical areas.

Patients with lesions restricted to the parietal cortex were found to be impaired selectively at predicting, through mental imagery, the time necessary to perform differentiated finger movements and visually guided pointing gestures, in comparison to normal individuals and to a patient with damage to the primary motor area.
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.

It is found that after oxytocin inhalation, patients exhibited stronger interactions with the most socially cooperative partner and reported enhanced feelings of trust and preference, suggesting a therapeutic potential of Oxytocin through its action on a core dimension of autism.

Parietal and premotor cortex regions are serious contenders for bringing motor intentions and motor responses into awareness and consciousness arise from increased parietal activity before movement execution.
The Involvement of the Orbitofrontal Cortex in the Experience of Regret
- N. Camille, G. Coricelli, J. Sallet, P. Pradat-Diehl, J. Duhamel, A. Sirigu

Facing the consequence of a decision we made can trigger emotions like satisfaction, relief, or regret, which reflect our assessment of what was gained as compared to what would have been gained by…
Racial Bias Reduces Empathic Sensorimotor Resonance with Other-Race Pain
Motor and Visual Imagery as Two Complementary but Neurally Dissociable Mental Processes
This work investigates the performance, by normal individual and subjects with a selective impairment in either motor or visual imagery, of an imagery task involving a mental rotation, and highlights the distinct but complementary contribution of covert motor and visual processes during mental rotation.
Altered awareness of voluntary action after damage to the parietal cortex
It is proposed that when a movement is planned, activity in the parietal cortex, as part of a cortico-cortical sensorimotor processing loop, generates a predictive internal model of the upcoming movement that might form the neural correlate of motor awareness.
Motor activation prior to observation of a predicted movement

- 1 December 2004
It is demonstrated in human subjects that motor activity also occurs prior to observing someone else's action, suggesting that the mere knowledge of an upcoming movement is sufficient to excite one's own motor system, enabling people to anticipate, rather than react to, others' actions.
