FUNCTIONAL CONNECTIVITY MODULATION INDUCED BY TRANSCRANIAL DIRECT CURRENT STIMULATION OF THE MOTOR NETWORK
Background: Brain functions arise from the orchestrated activation and cooperation of networks of regions whose specific relationship varies dynamically across functional states. Resting state functional Magnetic Resonance Imaging (RS-fMRI) analyses focuses on spontaneous low frequency fluctuations (< 0.1 Hz) in the BOLD signal and investigates synchronous activations between regions that are spatially distinct (functional connectivity, FC), occurring in the absence of a task or stimulus. Transcranial Direct Current Stimulation (tDCS) is a non-invasive brain stimulation technique that is known to modulate cortical activity and FC among brain regions, as measured by functional Magnetic Reson…
POST-THALAMOTOMY NEUROFUNCTIONAL FINDINGS ON PATIENTS TREATED WITH TRANS-CRANIAL MAGNETIC RESONANCE GUIDED FOCUSED ULTRASOUND SURGERY (TCMRGFUS): PRELIMINARY RESULTS
BACKGROUND AND PURPOSE: We present functional connectivity (FC) changes found in the very first patients treated with the first Italian installation of a trans-cranial MRI-guided Focused Ultrasound Surgery (tcMRgFUS) certified system for functional neurosurgery. TcMRgFUS is a promising new technique for non-invasive treatment of neurologic disorders such as Essential Tremor, tremor associated to Parkinson's Disease and Neuropathic Pain. TcMRgFUS is able to focally target and destroy specific regions in the brain through intact skull, by using a high intensity focused ultrasound beam. Resting state functional Magnetic Resonance Imaging (RS-fMRI) analyses focuses on spontaneous low frequency …
Atti del Workshop: Tecniche Speciali e Avanzate di Dosimetria e Radioprotezione
Atti del Workshop organizzato dall'Associazione Italiana di Radioprotezione (AIRP) in collaborazione con l'Università degli Studi di Palermo, dal titolo "Tecniche Speciali e Avanzate in Dosimetria e Radioprotezione" che si svolgerà venerdì 24 Giugno a Palermo presso l'Aula Magna del Dipartimento di Fisica e Chimica, Viale delle Scienze Edificio 18. L'evento rientra tra i 210 Eventi organizzati per i 210 anni dalla fondazione dell'Ateneo palermitano su iniziativa del Magnifico Rettore, Prof. Fabrizio Micari. L’evento prevede la discussione di 4 tematiche in ambito della dosimetria e della radioprotezione in campo sanitario ed ambientale (Dosimetria Clinica, Dosimetria Ambientale, Dosimetria …
