“…Furthermore, the superior test-retest reliability for eyes-closed compared to eyes-open restingstate conditions was consistent with previous findings (Corsi-Cabrera et al, 2007, Fernández et al, 1993, Cannon et al, 2012, suggestive of a higher reactivity to environmental influences with eyes-open than with eyes-closed (Barry et al, 2007, Corsi-Cabrera et al, 2007.…”

“…These findings are in accord with reliability data obtained for conventional lab-based EEG recording systems (Fernández et al, 1993, McEvoy et al, 2000, Salinsky et al, 1991, Burgess and Gruzelier, 1993, Corsi-Cabrera et al, 2007, Cannon et al, 2012. Reliability values from the portable EEG device also compare well to those reported for other commonly utilized functional measures, include resting (Zuo and Xing, 2014) and active fMRI (Bennett and Miller, 2010), PET/SPECT (Egerton et al, 2010, Catafau et al, 2008, and MEG (Martín-Buro et al, 2016).…”

“…Test-retest reliabilities of resting state qEEG in healthy individuals typically exceed 0.80 over intervals ranging from one-hour (Burgess andGruzelier, 1993, McEvoy et al, 2000), to onemonth (Cannon et al, 2012), to more than one-year (Hatz et al, 2014).…”

“…This normative data from across the lifespan during both resting and active EEG tasks can be used to reliably detect change in repeated measurements. The low CR values also suggest the stability of qEEG obtained from the ThinkGear system is a potentially sensitive biological marker for tracking longitudinal changes deviant from healthy individuals, but this requires further investigation (Cannon et al, 2012, Gudmundsson et al, 2007.…”

Recording systems to acquire electroencephalogram (EEG) data are traditionally lab-based. However, there are shortcomings to this method, and the ease of use and portability of emerging wireless EEG technologies offer a promising alternative. A previous validity study demonstrated data derived from a single-channel, wireless system (NeuroSky ThinkGear, San Jose, California) is comparable to EEG recorded from conventional lab-based equipment. The current study evaluated the reliability of this portable system using test-retest and reliable change analyses. Relative power (RP) of delta, theta, alpha, and beta frequency bands was derived from EEG data obtained from a single electrode over FP1 in 19 healthy youth (10-17 years old), 21 healthy adults (18-28 years old), and 19 healthy older adults (55-79 years old), during eyes-open, eyesclosed, auditory oddball, and visual n-back conditions. Intra-class correlations (ICCs) and Coefficients of Repeatability (CRs) were calculated from RP data re-collected one-day, one-week, and one-month later. Participants' levels of mood and attention were consistent across sessions. Eyes-closed resting EEG measurements using the portable device were reproducible (ICCs 0.76-0.85) at short and longer retest intervals in all three participant age groups. While still of at least fair reliability (ICCs 0.57-0.85), EEG obtained during eyes-open paradigms was less stable, and any change observed over time during these testing conditions can be interpreted utilizing the CR values provided. Combined with existing validity data, these findings encourage application of the portable EEG system for the study of brain function.

“…The sum of these processes is frequently called "brain maturation" by pediatric neurologists. LORETA results are of very good reliability in the run of 30 days (Cannon et al, 2012).…”
