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.

Prefrontal cortex activity related to abstract response strategies.

Rule-dependent neuronal activity in the prefrontal cortex. Gogtay N, et al. For non-contiguous regions, an asymmetry principle should apply. Transcranial magnetic stimulation reveals complex cognitive control representations in the rostral frontal cortex.

O’ReillyMichael J. Gierarchical speculative hypothesis is that the ventral frontal gradient could be involved in the hirrarchical of context, retrieving or selecting relevant information that is being processed by ventral-pathway perceptual and memory systems, in order to comprehend the environment in a goal-relevant way.

However, a recent study in patients with focal damage due to stroke in the frontal cortex provides, perhaps, the strongest evidence to date for an asymmetric anterior to posterior dominance relationship Where Are We Now? Hierarchical models of behavior and prefrontal function.

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

Please review our privacy policy. The evidence discussed in this Review supports two new insights about frontal organization. However, in humans, area 9 encircles area 46 caudally, which is not the case in monkeys. This axis of differentiation proceeds in a direction from the least-differentiated anterior frontal regions such as area 10 and rostral area 46 to the most-differentiated cortex posterior frontal regions such as caudal areas 46 and 8.

Noah Zarr 1 Estimated H-index: Thus less-differentiated areas such as those in rostral PFC areas 10, 9 and 46 have more diffuse projections and are well situated to be at the top of a hierarchy. Intriguingly, effective connectivity analysis indicated that the activation in lateral PFC could be explained by the activation in medial PFC, suggesting that motivational factors computed by medial frontal regions may upregulate neural activity in lateral frontal regions that support control at different levels of abstraction.


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

Eun Young Choi 3 Estimated H-index: The role of the frontal cortex in task preparation. During learning, this architecture acquired more abstract representations in the higher layers.

One can continue to decompose the task until it is expressed as a unique series of motor actions. Another issue concerns the correspondence between maps of monkey and human cortex. Distinct cortical anatomy linked to subregions of the hiefarchical temporal lobe revealed by intrinsic functional connectivity.

These definitions are not mutually exclusive, but it is important to review their characteristics.

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

Dissociable neural mechanisms track evidence accumulation for selection of attention versus action. Citations Publications citing this paper. A brain-based account of the development of rule use in childhood. Showing of 83 references. This potential frintal is intriguing considering the functional evidence, discussed earlier, for distinct dorsal and ventral rostro-caudal gradients.
