The prefrontal cortex: response selection or maintenance within working memory?
It is controversial whether the dorsolateral prefrontal cortex is involved in the maintenance of items in working memory or in the selection of responses. We used event-related functional magneticExpand

Connectivity-based subdivisions of the human right "temporoparietal junction area": evidence for different areas participating in different cortical networks.
Controversy surrounds the role of the temporoparietal junction (TPJ) area of the human brain. Although TPJ has been implicated both in reorienting of attention and social cognition, it is stillExpand

Shared Representations for Working Memory and Mental Imagery in Early Visual Cortex
Early visual areas contain specific information about visual items maintained in working memory, suggesting a role for early visual cortex in more complex cognitive functions [1-4]. It is an openExpand

On the relationship between the “default mode network” and the “social brain”
The default mode network (DMN) of the brain consists of areas that are typically more active during rest than during active task performance. Recently however, this network has been shown to beExpand

Integration of target and effector information in the human brain during reach planning.
To plan a reaching movement, the brain must integrate information about the location of the target with information about the limb selected for the reach. Here, we applied rapid event-related 3-TExpand

Spatial remapping of cortico-striatal connectivity in Parkinson's disease.
Parkinson's disease (PD) is characterized by striatal dopamine depletion, especially in the posterior putamen. The dense connectivity profile of the striatum suggests that these local impairments mayExpand

Gait-related cerebral alterations in patients with Parkinson's disease with freezing of gait.
Freezing of gait is a common, debilitating feature of Parkinson's disease. We have studied gait planning in patients with freezing of gait, using motor imagery of walking in combination withExpand

The Time Course of Changes during Motor Sequence Learning: A Whole-Brain fMRI Study
There is a discrepancy between the results of imaging studies in which subjects learn motor sequences. Some experiments have shown decreases in the activation of some areas as learning increased,Expand

Subcortical correlates of craving in recently abstinent alcoholic patients.
OBJECTIVE This study investigated functional cerebral correlates of craving in alcoholic patients and examined the state/trait characteristics of the regional cerebral network implicated in craving.Expand

A Functional Anatomy of Anticipatory Anxiety
Anticipatory anxiety is a complex combination of a future-oriented cognitive state, negative affect, and autonomic arousal. A dual-task paradigm of anticipation of electric shocks and aExpand
