Diffusion, perfusion and spectroscopy yield information, respectively, on the degree of cellularity, neoangiogenesis, presence/absence of necrosis and specific metabolites. Functional magnetic resonance imaging allows the presurgical planning and evaluation of risk and enables the patient to be fully aware at the time of informed consent. All these techniques represent an invaluable tool, otherwise unavailable in vivo, in the diagnosis of brain tumours

The experiments were carried out on one young monkey of 80-90 days of life and on three adult monkeys. The eye movements were detected by magnetic field technique, in the dark and in the light. A soft cup was used for painless fixation of young animal's head. The analysis of eye movements was done by a PDP 11/73. The results show that the spatio-temporal pattern of eye movements is prevalently vertical or slightly oblique in young monkey, contrary it is prevalently horizontal or slightly oblique in the adult: besides the amplitudes are smaller and the velocities are slower in the adult. From these preliminary results we may think that maturation modifies the static and dynamic characteristics of eye movements

The aim of this research is to study the effects of maturation, if there are any effects, on spatio-temporal characteristics of eye movements in the monkey. The experiments were carried out on one infant monkey (aged 80-90 days) and three adult monkey (Macaca nemestrina). Eye movements were detected by means of a magnetic field technique, in the dark and in the light. For painless fixation of the head Evart's technique was employed in adult monkeys while in the infant monkey a soft cup fixed to a suitable chair was used. The behavioural state was monitored by EEG and EMG. Eye movements were analised off-line by a PDP 11/73. Preliminary results show that the spatio-temporal pattern is prevalently vertical or slightly oblique in the infant monkey; on the contrary it is prevalently horizontal or oblique in the adults. Furthermore, the amplitudes of the saccades are smaller and the peak velocities are slower in the infant than in the adults. We may then argue that maturative processes act on ocular motility

Le "Tecniche avanzate di Risonanza Magnetica" consentono, al momento attuale, di ottenere informazioni su: 1) La velocita di diffusione delle molecole di acqua (Diffusione) nel tessuro cerebrale, alterata, ad esempio, in presenza di patologie che determinano una modificazione della cellularita o una condizione di edema vasogenico o citotossico; 2) La direzione preferenziale di movimento delle molecole di acqua (Tensore di diffusione), condizionata in primis dall' orientamento e dall'integrita dei fasci della sostanza bianca; 3) La perfusione ematica del tessuto cerebrale (Perfusione), alterata in tutte le condizioni che determinano una neoangiogenesi oppure una ipoperfusione; 4) Metaboliti, ad esempio correlati al metabolismo delle membrane cellulari, alla funzionalita dei neuroni, ai fenomeni di necrosi cellulare (Spettroscopia); 5) Le variazioni del consumo di ossigeno del tessuto cerebrale (Attivazione), determinate ad esempio dall'esecuzione di un compito motorio, ideativo, o dalla percezione di stimoli uditivi, visivi, etc
