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 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)
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)
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)
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)
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)
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)
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)
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)
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)
