IS THE ROSTROCAUDAL AXIS OF THE FRONTAL LOBE HIERARCHICAL PDF

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.

Two potential explanations have been given to reconcile this result with those reported in the broader literature on abstraction and PMd 69 First, we evaluate neural recording, neuropsychological and functional imaging data that support a rostro-caudal gradient of function, focusing on possible regional differences in the response to different levels of abstraction.

Is the rostro-caudal axis of the frontal lobe hierarchical?

Evidence for a functional gradient along the dorsal rostro-caudal axis The strongest evidence to date for hiierarchical functional gradient along the rostro-caudal axis of the frontal lobes comes from human fMRI studies in which the level of abstraction of response selection was progressively varied in each individual participant. Specifically, during the course of learning, monkeys often adopt abstract strategies, like shifting to hierarchicsl new response after receiving negative feedback but sticking to the same response after positive feedback.

Prefrontal neural correlates of memory for sequences.

Is the rostro-caudal axis of the frontal lobe hierarchical?

In particular, these patients were impaired at making action decisions at a level of abstraction that was dependent on whether their damage was in pre-PMd caudal, more concrete or mid-DLPFC more rostral, more abstract. A simple rule linking a stimulus and a response is a first order policy.

Meier 2 Estimated H-index: Hence, although having a structurally arrayed hierarchical organization is not a requirement for the control of complex sequential behaviourwhen such an architecture exists, the same action can be represented at different levels of abstraction.

Author manuscript; available in PMC Jan Functional magnetic resonance imaging evidence for a hierarchical organization of the prefrontal cortex. Part b is reproduced, with permission, from REF.

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 fronfal responses that form these sequences. Facilitated processing of a stimulus upon repetition, which happens even following an extended delay.

Simulating a skilled typist: In this chapter, anatomists Petrides and Pandya report an extensive comparison of the architecture of the frontal cortex between monkeys and humans. See other articles in PMC that cite the published article. Evidence for a Functional Hierarchy of Association Networks. This revealed that both in monkeys and humans, areas 9 and 46 are in the mid-dorsolateral sector of the lateral prefrontal cortex.

But do these distinct rostro-caudal tracts form coherent functional systems, as would be required by a special rostro-caudal processing architecture such as a hierarchy?

In this sense, policy abstraction relates directly to rule complexity. Monkeys learnt to respond depending on whether a presented stimulus did or did not match a target stimulus. Die Cortexgliederung des Menschen.

Role of the lateral prefrontal cortex in executive behavioral control. Integrated externally and internally generated task predictions jointly guide cognitive control in prefrontal cortex Jiefeng JiangAnthony D. This authoritative review provides a fundamental background on the cognitive control function of the PFC. To resolve these discrepancies, Petrides and Pandya 10, performed an extensive comparison of the architecture of the frontal cortex between monkeys and humans.

The network also included regions of medial frontal cortex, anterior insula, the head of yierarchical caudate nucleus and anterior inferior parietal lobule.
