Abstract
In the last years the role of sensory rhythmic stimulation (SRS) on motor rehabilitation in PD has become a new line of interest for researches and therapists given the promising results reported in scientific literature. This kind of strategies present a whole range of features which make it very appealing for its daily use, namely, they are easy to use, they have not distorting side-effects, and, chiefly, their effectiveness have been reported either in presence as in absence of antiparkinsonian medication.

A 2D Positioning Application in PET Using ANNs
PET is a nuclear imaging technique based on the administration of radioactive substances (radiotracers), whose molecules have a radioactive isotope (radionuclide), to a patient under study, with the aim to trace some chemical or physiological process that takes place in the body, typically for diagnosis of heart diseases, cancer, etc. The images obtained in a PET system are 2D sections of the concentration distribution of a radiotracer inside the body. When joining these sections, a medical 3D image can be obtained.

A Grid Paradigm for e-Science Applications
A nuclear medicine medical imaging technique which produces a three-dimensional image or map of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radioisotope, which is introduced into the body on a metabolically active molecule; images of metabolic activity in space are then reconstructed by computer analysis.
