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)
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)
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)
In the nineteenth century, epilepsy became subject of experimental research. Lombroso established a relationship between epilepsy and criminality believing in the existence of epileptoid traits and atavism. He tried to demonstrate the common origin of epilepsy, criminality, and genius; factors deteriorating the CNS would act upon centers, which control(More)
Electrophysiological studies indicate that Unverricht-Lundborg's disease (ULD), the most common form of progressive myoclonus epilepsy in Europe, is characterized by the involvement of multiple cortical regions in degenerative changes that lead to enhanced excitation and deficient inhibition. We searched for the haemodynamic correlates of these effects(More)
This paper reviews experimental evidence and presents new data supporting the idea that human language may have evolved from hand/mouth action representation. In favor of this hypothesis are both anatomical and physiological findings. Among the anatomical ones is the fact that the monkey homologue of human Broca's area is a sector of ventral premotor cortex(More)
Central pontine myelinolysis is an acquired, non-inflammatory demyelinating lesion usually localized in the brainstem pons basis; it usually affects patients with a history of chronic alcoholism, malnutrition or dysionemia. The exact pathogenesis of myelinolysis is still unclear. A 69-year-old Caucasian male presented intensive headache and underwent(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)
The reported annual incidence of juvenile stroke ranges from 9 to 47 cases per 100,000 inhabitants. We sought to estimate the incidence of first-ever stroke in young adults through a population-based stroke registry in a well-defined and stable population. We planned to collect all cases of new stroke in people aged 15-44 years in Ferrara, Italy, over the(More)
