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.

Brain Res Cogn Brain Res. Neural mechanisms of visual working memory in prefrontal cortex of the macaque.
However, what distinguishes this ventral gradient from the dorsal gradient discussed previously remains an open question. Maintenance versus manipulation of information held in working memory: Are the functional gradients hierarchical? 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 To understand why actions might be processed hierarchically by the brain, consider the act of making a sandwich.
Lesioning the PMd following training results in a loss of the ability to select responses on the basis of previously learnt rules 5159 — An integrative theory of prefrontal cortex function.
Interestingly, a recent experiment has provided evidence for interactions between parallel rostro-caudal gradients along lateral and medial frontal cortex as more-abstract motivational factors are taken into consideration during cognitive control MyersRachel M. BlumenfeldDaniel P.
Rostro-caudal Architecture of the Frontal Lobes in Humans. Christoff K, et al. Amitai Shenhav 13 Estimated H-index: Thus, PFC neurons can maintain an abstract sequential movement plan, rather than individual movements. Neuroscience of Rule-Guided Behavior. Sakai K, Passingham RE. Prefrontal cortex and dynamic categorization tasks: This potential independence is intriguing considering the functional evidence, discussed earlier, for distinct dorsal and ventral rostro-caudal gradients.
Cognitive control refers to the ability of humans and other primates to internally guide behavior in concert with goals, plans, and broader contextual knowledge. Showing of 5 extracted citations.
Anatomy, Physiology, and Neuropsychology of the Frontal Lobe. Each of these two broad cortical regions shows a gradient of laminar organization for example, differentiation from the most anterior to more-posterior portions of the frontal cortex.

Oxford University Press; New York: Giovanni Pezzulo 32 Estimated H-index: This review discusses the various forms of abstraction that have been proposed to account for functional differences along the rostro-caudal axis of the frontal cortex, considering their common and potentially distinguishing characteristics.
Carolyn Ranti 1 Estimated H-index: Important differences along the rostro-caudal axis of the frontal lobe can be seen during grey matter development throughout childhood and early adolescence. An information theoretical approach to prefrontal executive function. This strategy becomes obsolete once the arbitrary associations have been learnt; thus, PFC lesions have little effect after learning.
This revealed that both in monkeys and humans, areas 9 and 46 are in the mid-dorsolateral sector of the lateral prefrontal cortex. For example, these cells will fire in advance of the push-push-pull-pull and pull-pull-push-push sequences even though these differ in terms of their specific movements Shaw P, et al.
For example, rostral area 46 projects to area 10, which is less differentiated, and to area 8, which is more differentiated. In this framework, the cerebral cortex evolved from two primordial parts: This paper reviews computational accounts of hierarchical control of behaviour and their relationship to frontal lobe function.

Is the rostro-caudal axis of the frontal lobe hierarchical?
Adding additional contingencies will progressively result in more abstract policy. The lateral premotor cortex area 6 is divided into a dorsal region containing a representation of the trunk and a ventral region representing the neck, head and face.
