Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Mapping the cortical representation of the lumbar paravertebral muscles [PDF]
, 2007 Objective: The aim of this study was to map the cortical representation of the lumbar spine paravertebral (LP) muscles in healthy subjects. Methods: Transcranial magnetic stimulation (TMS) was employed to map the cortical representations of the LP ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

Neuronal activity (c-Fos) delineating interactions of the cerebral cortex and basal ganglia
Frontiers in Neuroanatomy, 2014 The cerebral cortex and basal ganglia (BG) form a neural circuit that is disrupted in disorders such as Parkinson’s disease. We found that neuronal activity (c-Fos) in the BG followed cortical activity, i.e., high in arousal state and low in sleep state.

Cortical development: A role for spontaneous activity? [PDF]
Current Biology, 1997 Patterned spontaneous activity seems important in the development of the retina and its projections, and it has now been shown that early retinal activity is faithfully transmitted through the thalamus. The modular organization of the visual cortex is also dependent on activity but not necessarily that originating in the retina.

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Cortical control of smooth pursuit eye movements [PDF]
, 2007 In this PhD project, the functions of cortical regions that control smooth pursuit eye movements (SPEM) and visual attention were investigated. Combining behavioural (eye movement) measurements and functional magnetic resonance imaging (fMRI) the ...
