An evolutionary computational theory of prefrontal executive function in decision-making
The prefrontal cortex subserves executive control and decision-making, that is, the coordination and selection of thoughts and actions in the service of adaptive behaviour. We present here a computational theory describing the evolution of the prefrontal cortex from rodents to humans as gradually adding new inferential Bayesian capabilities for dealing with a computationally intractable decisio...
متن کاملRole of the lateral prefrontal cortex in executive behavioral control.
The lateral prefrontal cortex is critically involved in broad aspects of executive behavioral control. Early studies emphasized its role in the short-term retention of information retrieved from cortical association areas and in the inhibition of prepotent responses. Recent studies of subhuman primates and humans have revealed the role of this area in more general aspects of behavioral planning...
متن کاملNeuronal mechanisms of executive control by the prefrontal cortex.
Executive function is considered to be a product of the coordinated operation of various processes to accomplish a particular goal in a flexible manner. The mechanism or system responsible for the coordinated operation of various processes is called executive control. Impairments caused by damage to the prefrontal cortex are often called dysexecutive syndromes. Therefore, the prefrontal cortex ...
متن کاملPrefrontal cortical minicolumn: from executive control to disrupted cognitive processing.
The prefrontal cortex of the primate brain has a modular architecture based on the aggregation of neurons in minicolumnar arrangements having afferent and efferent connections distributed across many brain regions to represent, select and/or maintain behavioural goals and executive commands. Prefrontal cortical microcircuits are assumed to play a key role in the perception to action cycle that ...
متن کاملExecutive control and decision-making in the prefrontal cortex
action sets thus comprise multiple stimulusaction and (stimulus)-action-outcome associations, which are learned and continuously adjusted online for maximizing rewards. Computational modeling suggest that stimulus-action and (stimulus)-action-outcome associations are learned and adjusted through reinforcement and statistical learning respectively [33 ,34], while abstract action sets emerge thro...
