Diffusion Weighted Magnetic Resonance Imaging (DW-MRI) and tractography approaches are the only tools that can be utilized to estimate structural connections between different brain areas, non-invasively and in-vivo. A first step that is commonly utilized in these techniques includes the estimation of the underlying fibre orientations and their uncertainty(More)
Integrating electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) data may help to optimize anatomical and temporal resolution in the investigation of cortical function. Successful removal of fMRI scanning artifacts from continuous EEG in simultaneous recordings has been reported. We assessed the feasibility of recording reliable(More)
We investigated the neural correlates underlying response inhibition and conflict detection processes using ERPs and source localization analyses simultaneously acquired during fMRI scanning. ERPs were elicited by a simple reaction time task (SRT), a Go/NoGo task, and a Stroop-like task (CST). The cognitive conflict was thus manipulated in order to probe(More)
OBJECTIVES The time course of mu and beta sensorimotor rhythms, with event-related desynchronisation (ERD) to preparation and execution of voluntary movement followed by synchronisation (ERS) after movement, is considered to indicate cortical activation and idling, respectively. We investigated ERD and ERS in amyotrophic lateral sclerosis (ALS) patients and(More)
Normal aging is associated with several modifications in the cerebral motor system that reflect into an increased and more bilateral activation in elderly subjects. Twelve young and nine elderly healthy right-handed subjects performed a self-initiated brisk right thumb extension while recorded with 32-channel EEG. The aging effect over cortical generators(More)
The localization of human hand primary motor area (M1) has been the object of several studies during the last decades. EEG source analysis, functional magnetic resonance imaging (fMRI) and focal transcranial magnetic stimulation (TMS) are non-invasive methods for localizing M1 with good accuracy compared to direct electrocorticography (ECoG) results. EEG(More)
Cortico-striatal-thalamic network functional connectivity (FC) and its relationship with levodopa (L-dopa) were investigated in 69 patients with hemiparkinsonism (25 drug-naïve [n-PD] and 44 under stable/optimized dopaminergic treatment [t-PD]) and 27 controls. Relative to controls, n-PD patients showed an increased FC between the left and the right basal(More)
Resting state functional connectivity of the sensorimotor and extramotor brain networks was studied in 24 patients with primary lateral sclerosis (PLS) relative to 26 healthy controls. The relationships of RS functional connectivity with patient clinical and cognitive status and white matter tract damage (i.e., corticospinal tracts, corpus callosum, and(More)
After acute stroke several changes in cortical excitability occur involving affected (AH) and unaffected hemisphere (UH) but whether they contribute to motor recovery is still controversial. We performed transcranial magnetic stimulation mapping of several upper limb muscles over the two hemispheres in thirteen patients at 4-12 days from subcortical stroke(More)
Cortical reorganization to simple movement in patients with amyotrophic lateral sclerosis (ALS) has been investigated in neuroimaging studies, reporting recruitment of ipsilateral primary sensorimotor (iSMC) and premotor regions (PMd). In order to investigate the spatiotemporal pattern of such overactivation, EEG source analysis to brisk self-paced finger(More)
