Broca's area has been considered, for over a century, as the brain centre responsible for speech production. Modern neuroimaging and neuropsychological evidence have suggested a wider functional role is played by this area. In addition to the evidence that it is involved in syntactical analysis, mathematical calculation and music processing, it has recently(More)
OBJECTIVE To evaluate the viability of MEG source reconstruction in the presence of large interference due to orthodontic material. METHODS We recorded the magnetic fields following a simple hand movement and following electrical stimulation of the median nerve (somatosensory evoked field -SEF). These two tasks were performed twice, once with and once(More)
Studies on the distribution of multiple sclerosis (MS) carried out in Southern Europe in the last years have shown a significant increase in the frequency of the disease. A previous descriptive survey in the Republic of San Marino, northern Italian peninsula, published in 1984 established that this area is at high risk for MS. We updated the frequency(More)
The antagonistic interaction between adenosine and dopamine receptors could have important pathophysiological and therapeutic implications in Parkinson's disease (PD). The primary aim of this study was to investigate the expression, affinity, and density of A(1), A(2A), A(2B), and A(3) adenosine receptors (ARs) and D(2) dopamine receptors (D(2)Rs) in PD. An(More)
OBJECTIVE Recent evidence mainly based on hemodynamic measures suggests that the impairment of functional connections between different brain areas may help to clarify the neuronal dysfunction occurring in patients with disorders of consciousness (DOC). The aim of this study was to evaluate effective EEG connectivity in a cohort of 18 patients in a chronic(More)
The purpose of the present study is to evaluate accelerometric parameters of gait in different neurological conditions with pathological gait impairment compared to healthy subjects. We studied 17 patients affected by Parkinson’s disease, 24 with ataxic gait due to different diseases and 24 healthy subjects supplied with a triaxial accelerometer with a(More)
We performed simultaneous acquisition of EEG-fMRI in seven patients with Unverricht-Lundborg disease (ULD) and in six healthy controls using self-paced finger extension as a motor task. The event-related desynchronization/synchronization (ERD/ERS) analysis showed a greater and more diffuse alpha desynchronization in central regions and a strongly reduced(More)
UNLABELLED (18)F-(E)-N-(3-iodoprop-2-enyl)-2β-carbofluoroethoxy-3β-(4'-methyl-phenyl) nortropane ((18)F-FE-PE2I) is a recently developed radioligand for the in vivo quantification of the dopamine transporter (DAT) in the striatum and substantia nigra (SN). The aim of this study was to examine the suitability of (18)F-FE-PE2I as a tool for imaging the(More)
In Alzheimer’s disease (AD), increased metabolism of monoamines by monoamine oxidase type B (MAO-B) leads to the production of toxic reactive oxygen species (ROS), which are thought to contribute to disease pathogenesis. Inhibition of the MAO-B enzyme may restore brain levels of monoaminergic neurotransmitters, reduce the formation of toxic ROS and reduce(More)
OBJECTIVE To determine the prevalence of anaemia and to evaluate the factors that condition its occurrence.Setting. Out-patient clinics in the La Plata area, Buenos Aires, Argentina. DESIGN Observational and prospective study. PARTICIPANTS All the pregnant women consulting for the first time, excluding those with prior pathology or regular use of(More)
