Research Abstract |
It has been hypothesized that the emotion is embodied from psychological, behavioral and physical reactions elicited by reward. This is the first study that shows the correlation between behavioral and physical reactions under reward-guidedbehavior performed by macaque monkeys. Furthermore, the recordings from single neurons in monkey insulae during reward-seeking showed that the insulae responded to reward expectation. These results suggest that the interoception elicited by reward might provide a foundation for emotional and motivational reactions. These findings were reported in Journal of neurophysiology in 2012.
