Assembly and Use of New Task Rules in Fronto-parietal Cortex

Iroise Dumontheil, Russell Thompson, John Duncan
2011 Journal of Cognitive Neuroscience  
We suggest that, as a new task is learned, a fronto-parietal representation of relevant rules and facts is assembled for future control of behavior.  ...  ■ Severe capacity limits, closely associated with fluid intelligence, arise in learning and use of new task rules.  ...  Conclusion Together, our results show a broad role of fronto-parietal MD regions in comprehension, assembly, and use of new task rules.  ...

A Long-Range Fronto-Parietal 5- to 10-Hz Network Predicts "Top-Down" Controlled Guidance in a Task-Switch Paradigm

J. M. Phillips, M. Vinck, S. Everling, T. Womelsdorf
2013 Cerebral Cortex  
Subdivisions within prefrontal cortex are implicated to encode attentional task sets and to update changing task rules, particularly when changing task demands require top-down control.  ...  These findings reveal a 5-to 10-Hz coordinated, long-range fronto-parietal network prior to actual task-relevant stimulus processing, particularly when subjects engage in controlled task processing modes  ...  The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Fronto-parietal, cingulo-opercular and striatal contributions to learning and implementing control policies [article]

Apoorva Bhandari, David Badrre
2020 bioRxiv   pre-print
The cognitive and neural basis of control policy implementation remains poorly characterized, in part because it is typically confounded with implementing new stimulus-response rules.  ...  This pattern of activity dissociated these regions from a fronto-parietal network including dorsolateral PFC, inferior frontal junction, inferior parietal sulcus, and rostrolateral PFC, which showed a  ...  We thank Celia Ford and Brittany Ciullo for assistance with data collection, and Christopher Chatham & Theresa Desrochers for useful discussions.  ...

An integrative architecture for general intelligence and executive function revealed by lesion mapping

A. K. Barbey, R. Colom, J. Solomon, F. Krueger, C. Forbes, J. Grafman
2012 Brain  
Impaired performance on these measures was associated with damage to a distributed network of left lateralized brain areas, including regions of frontal and parietal cortex and white matter association  ...  The observed findings support an integrative framework for understanding the architecture of general intelligence and executive function, supporting their reliance upon a shared fronto-parietal network  ...  Reding and G.

Dissociating the Roles of the Rostral Anterior Cingulate and the Lateral Prefrontal Cortices in Performing Two Tasks Simultaneously or Successively

J.-C. Dreher
2003 Cerebral Cortex  
In contrast, switching between two tasks, relative to performing them simultaneously, activated the left lateral prefrontal cortex and the bilateral intra-parietal sulcus region.  ...  More importantly, we found that the anterior cingulate and the lateral prefrontal cortices were differently activated in dual-task and task-switching situations.  ...  A recent event-related fMRI study of task switching also supported a specific role of the left fronto-lateral cortex in the selection of cue-related task rules (Brass and von Cramon, 2002) .  ...

Behavior in Oblivion: The Neurobiology of Subliminal Priming

Christianne Jacobs, Alexander T. Sack
2012 Brain Sciences  
However, this is not to say that recurrent processing is sufficient for consciousness, as a neural definition of consciousness in terms of recurrent connectivity would imply.  ...  Subliminal priming refers to behavioral modulation by an unconscious stimulus, and can thus be regarded as a form of unconscious visual processing.  ...  Acknowledgements We express gratitude to Felix Duecker for useful discussions and to two anonymous referees for suggestions how to further improve the manuscript.  ...
