In the present study, we investigated whether EEG indices derived from passive brain-computer interfaces can be used to track emotional arousal changes during continuous EEG recording. Global synchronization index (GFS), a measure known to reflect human cognitive process, was evaluated to quantify the global synchronization of multichannel EEG data recorded from a group of participants while they...
The recently developed global synchronization index (GSI) quantifies synchronization between neuronal signals at multiple sites. This study explored the clinical significance of the GSI in Alzheimer's disease (AD) patients.Electroencephalograms were recorded from 25 AD patients and 22 age-matched healthy normal controls (NC). GSI values were computed both across the entire frequency band and separately...
Global field synchronization (GFS) has recently been introduced to measure functional synchronization in frequency-domain EEG data. This study explored GFS values and its clinical significance in patients with Alzheimer's disease (AD).EEGs were recorded from 22 AD patients and 23 age-matched healthy controls. GFS values were computed in the delta, theta, alpha, beta1, beta2, beta3, gamma, and full...
