frontal lobes are organized along their rostrocaudal axis to support hierarchical frontal networks interact via local and global hierarchical structure to support. An influential class of theory proposes that the frontal lobes are organized along their rostrocaudal axis to support hierarchical cognitive control. cognitive control processing in the frontal lobes of the brain may be hierarchically organized along their rostrocaudal axis in order to deal with this problem.

Functional specialization within rostral prefrontal cortex area Neural correlates of memory retrieval and evaluation. Amemori K, Sawaguchi T. A recent repetition priming experiment has provided more direct evidence of a ventrolateral PFC gradient of abstraction Don’t have an account?
Salience, State, and Expression: This papers reports an elegant experiment showing that single-unit recording in monkeys provides evidence that neurons in prefrontal cortex are tuned to abstract categories of response sequences that generalize across the specific responses that form these sequences.
Likewise, single-unit recording experiments have revealed that frontal neurons are highly flexible, capable of changing their tuning properties as task demands change Differential involvement of neurons in the dorsal and ventral premotor cortex during processing of visual signals for action planning.
Subdivisions and connectional networks of the lateral prefrontal cortex in the macaque monkey. In particular, the asymmetry and direction of influence that a hierarchical gradient would predict have only recently been directly tested Petrides M, Pandya DN. In the verbal domain, semantic refers to word meanings. Domains are often associated with independent or modular input systems Action rule A type of knowledge that specifies how to behave given a particular state. Prefrontal cortex and dynamic categorization tasks: In general, as action goals become more abstract, the timescale of action that they govern increases.

The frontopolar cortex and human cognition: This developmental pattern is significant for models of frontal lobe function, particularly those that seek to understand how a hierarchical architecture might develop in the frontal cortex for examples see REFS 2627 What does one press in response to a rosfrocaudal circle?
A stimulus-to-response mapping is a simple rule Semantic Conceptual knowledge, beliefs and facts about the world.
Selection, integration, and conflict monitoring; assessing the nature and generality of prefrontal cognitive control mechanisms. Importantly, the sites of damage among patient groups corresponded precisely to the foci identified for these levels of abstraction in healthy controls undergoing fMRI while performing this task Fronral influential class of theory proposes that the frontal lobes are organized along their rostrocaudal axis to support hierarchical cognitive control.
Etienne KoechlinChristopher Summerfield Trends in cognitive sciences In this sense, policy abstraction relates directly to rule complexity. Area 45 shown rostrocauval blue revealed repetition priming at the decision level even if the subsequent response differed. Interestingly, no efferent projections from area 6 to FPC rostrocqudal 10 were found.

They showed that areas 44 and 8 shown in orange in caudal ventrolateral PFC showed repetition priming at the response level, that is, the signal change in these areas diminished when a motor response was repeated, regardless of the stimulus or decision associated with it. However, lesioning the mid-dorsolateral PFC after rule learning does not impair performance on simple response-selection tasks. Picard N, Strick PL.

National Center for Biotechnology InformationU. Jiefeng Jiang 7 Estimated H-index: Our review of the evidence supports neither a unitary model of lateral frontal function nor a unidimensional abstraction gradient. However, there is also evidence for a rostro-caudal gradient of abstraction along the ventrolateral frontal cortex
