The MR-compatible VISUASTIM system includes: a slim visor 20/20 and an integrated eye-tracker camera; a high-resolution projector-based system; an accompanying stereo audio stream with complete frequency response at the range of 40-40,000 hz ; a 10 button response pad subdivided in 2 blocks of five for every hand, adequate even in the need for bimanual response; a 5-button
Background: Chronic migraine (CM) can be associated with aberrant long-range connectivity of MRI-derived resting-state networks (RSNs). Here, we investigated how the fractal dimension (FD) of blood oxygenation level dependent (BOLD) activity may be used to estimate the complexity of RSNs, reflecting flexibility and/or efficiency in information processing in CM patients respect to healthy controls (HC). Methods: Resting-state MRI data were collected from 20 untreated CM without history of medication overuse and 20 HC. On both groups, we estimated the Higuchi's FD.
