Distinct cognitive mechanisms in a gambling task share neural mechanisms.
Distinct psychological processes have been proposed to unfold in decision-making. The time course of neural mechanisms supporting these processes has not been fully identified. The present MEG study examined spatio-temporal activity related to components of decision-making proposed to support reward valuation, reward prediction, and outcome evaluation. Each trial presented information on reward...
متن کاملCommon and Distinct Neural Mechanisms
Emotions are generally thought to arise through the interaction of bottom-up and top-down processes. However, prior work has not delineated their relative contributions. In a sample of 20 females, we used functional magnetic resonance imaging to compare the neural correlates of negative emotions generated by the bottom-up perception of aversive images and by the top-down interpretation of neutr...
متن کاملTwo distinct neural mechanisms underlying indirect reciprocity.
Cooperation is a hallmark of human society. Humans often cooperate with strangers even if they will not meet each other again. This so-called indirect reciprocity enables large-scale cooperation among nonkin and can occur based on a reputation mechanism or as a succession of pay-it-forward behavior. Here, we provide the functional and anatomical neural evidence for two distinct mechanisms gover...
متن کاملComputational and neural mechanisms of task switching
Switching between tasks that overlap in perceptual and response characteristics is assumed to rely upon the maintenance of task representations in prefrontal cortex (PFC). However, task-switching studies demonstrate ‘‘switch costs,’’ even when there is sufficient time to prepare for a new task. These costs suggest that task-switching performance reflects a complex interplay between priming and ...
متن کاملCOMMEMORATIVE LECTURE Neural mechanisms of cognitive memory
It is my great honor to be here for the award of the 2003 Keio Medical Science Prize. I express my gratitude to Keio University and Dr. Mitsunada Sakaguchi. Knowledge or experiences are voluntarily recalled from memory by reactivation of their neural representations in the cerebral association cortex. Four questions are central in understanding this process: (1) Where in the brain is the mnemon...
