Task Difficulty Manipulation Reveals Multiple Demand Activity but no Frontal Lobe Hierarchy
It has been proposed that task control is functionally implemented by a distributed frontoparietal system. It has been argued that one component of this system, the lateral frontal cortex, is functionally organized through a caudal to rostral gradient. Here, we tested 2 competing models, the Information Cascade and Rule Abstraction hypotheses, which suggest different principles underlying the r...
متن کاملTwenty questions task and frontal lobe dysfunction.
Performance on the Twenty Questions task has been assumed to be deficient in those with frontal lobe damage, although few studies have specifically examined this. In the present study, 88 participants with frontal lobe epileptic dysfunction were assessed on this task, as were 57 participants with temporal lobe epileptic disturbance and 28 participants with no evidence of any neurological damage...
متن کاملGlobal Increase in Task-related Fronto-parietal Activity after Focal Frontal Lobe Lesion
A critical question for neuropsychology is how complex brain networks react to damage. Here, we address this question for the well-known executive control or multiple-demand (MD) system, a fronto-parietal network showing increased activity with many different kinds of cognitive demand, including standard tests of fluid intelligence. Using fMRI, we ask how focal frontal lobe damage affects MD ac...
متن کاملContent- and task-specific dissociations of frontal activity during maintenance and manipulation in visual working memory.
Working memory, the short-term maintenance and manipulation of information, relies strongly on neural activity in the frontal cortex. Understanding the functional role of this activity is a prerequisite for the understanding of cognitive control mechanisms. Functional imaging studies in human participants have attempted to reveal neural correlates of the subdivision of visual working memory int...
