Cerebral causes and consequences of parkinsonian resting tremor: a tale of two circuits?
… (B) In the cerebello-thalamo-cortical circuit, we found two separate effects: (i) cerebral activity
… The line graphs in B and C show three relevant time courses: (i) brain activity (motor cortex …

No double-dissociation between optic ataxia and visual agnosia: Multiple sub-streams for multiple visuo-manual integrations
The current dominant view of the visual system is marked by the functional and anatomical
dissociation between a ventral stream specialised for perception and a dorsal stream …

The pathophysiology of essential tremor and Parkinson's tremor
We review recent evidence about the pathophysiology of essential tremor and tremor in
Parkinson’s disease. We believe that a network perspective is necessary to understand this …

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 …

[HTML][HTML] 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 …

Connectivity-based subdivisions of the human right “temporoparietal junction area”: evidence for different areas participating in different cortical networks
… The size of this cross-correlation matrix is number of seeds × number of seeds and the (i,j)th
element value is the correlation between the connectivity profile of TPJ voxel i and the …

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 …

[PDF][PDF] 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 …

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 …
