MEMORIA MOTORIA Protocollo di riabilitazione cognitiva dei disturbi del movimento, il ruolo della corteccia motoria primaria. Utilizzo di metodiche d…
l'obiettivo della presenti tesi è stato quello di verificare il ruolo della corteccia motoria primaria in un test cognitivo di memorizzazione e riconoscimento di immagini di movimento suddivisi in sequenza. Sono stati utilizzati strumenti di modulazione dell'attività cerebrale quali la TMS ( stimolazione magnetica transcranica) e per la registrazione dei MEP (potenziali evocati motori) e la tDCS (stimolazione cerebrale a corrente diretta) e per la modulazione dell'attività cerebrale durante lo svolgimento del compito cognitivo. Questi studi sono stati condotti grazie alla partecipazione di soggetti sani e soggetti con lesione cerebrale dell'emisfero desrtro. I risultati ottenuti sembrano di…

Clinical effects of different montages of Transcranial Direct Current Stimulation (tDCS) in patients with Parkinson’s Disease
2016
Background: Parkinson’s disease (PD) is characterized by motor deficits which may not completely respond to the dopaminergic therapy, thus posing a therapeutic challenge. Non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) have shown promising results as possible alternative of treatment in different neurological disorders including PD. The therapeutic effect of tDCS, which may increase (anodal currents) or decrease (cathodal currents) the cortical excitability level, likely relies on modulation of cortico-subcortical interactions and abnormal patterns of cortical activation. Objective: To investigate safety and therapeutic potential of different…
Functional connectivity modulation induced by transcranial direct current stimulation of the motor network: a Resting-State fMRI study
2016
Resting-state functional connectivity represents a novel fMRI approach that allows detection of temporal correlations in spontaneous BOLD signal oscillations while subjects rest quietly in the scanner. Functional connectivity (FC) can be defined as the synchrony of neural activity among spatially distant regions. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that is known to modulate cortical activity and FC among brain regions. This study is aimed at measuring the variation of functional connectivity between cortical brain regions after tDCS along time. The temporal concatenation group ICA showed that immediately after anodal stimulation the a…
SHORT-TERM SYNAPTIC PLASTICITY IN MIGRAINE MOTOR CORTEX: EVIDENCE BY PRECONDITIONING OF HIGH-FREQUENCY REPETITIVE TRANSCRANIAL MAGNETIC STIMULATION (…
2011
Background: Brief 5Hz repetitive transcranial magnetic stimulation (rTMS) trains at 120% of the resting- motorthreshold (RMT) intensity determine in healthy subjects a potentiation of motor evoked potentials (MEPs), likely due to short-term presynaptic plasticity facilitation. We recently showed paradoxical intensity-dependent MEP changes to 5Hz rTMS in migraine with MEP facilitation at 110% and inhibition at 130% RMT. This provides evidence of both hyper-responsivity and self-limiting hyperexcitability capacity in migraine, likely due to earlier activation of inhibitory homeostatic plasticity mechanisms. To explore this, we applied in migraineurs cathodal transcranial Direct Current Stimul…

This study is aimed at measuring the variation of functional connectivity between cortical brain regions after tDCS along time. For this purpose we enrolled 20 healthy right-handed subjects.
The transcranial stimulation with direct currents (tdcs): An historical and conceptual minireview
2018
Transcranial Stimulation with Direct Currents (tDCS) is a method for non invasive brain stimulation created to induce functional changes in cerebral cortex. tDCS consists of application on the scalp of electrodes providing a low intensity direct current influencing neuronal functions. tDCS is not the only neurostimulation method for neuroscience clinical practice and research and can be used for treat many different clinical conditions such as migraine prevention, autism spectrum disorders (ASD), cerebral palsy rehabilitation, post-traumatic brain injury neuropsychological disorders.
