Exploring resting-state EEG brain oscillatory activity in relation to cognitive functioning in multiple sclerosis

Early and late dot‐probe attentional bias to mild and high threat pictures: Relations with EEG theta/beta ratio, self‐reported trait attentional control, and trait anxiety

“…Contrary to Angelidis et al (2018), a significant correlation between TBR and ACS scores (independent of trait anxiety) was found in the current sample, which is in line with previous studies from our lab (Angelidis et al, 2016;Putman et al, 2010Putman et al, , 2014 and with reported negative correlations between TBR and task-based objective measures of attention (Keune et al, 2017). Conceptualizing TBR as a marker of attentional control, we also predicted that ACS scores (which indicate trait AC) would show a similar relation with dot-probe task performance as TBR.…”

“…This conceptually replicates the TBR effect, but only when taking cue‐target delay into consideration, which is largely consistent with our predictions. Although TBR was reported to have a very high 1‐ and 2‐week retest reliability (Angelidis et al, ; Keune et al, ), little is known about transient state fluctuations of TBR, and operationally our TBR measure was done at a single point in time. Since acute fluctuations in trait AC may occur as a function of factors as diverse as fatigue (Van der Linden, Frese, & Meijman, ) or circadian rhythm (Van Dongen & Dinges, ), results for trait and state measures of trait AC should not be expected to correlate perfectly.…”

“…TBR has been suggested to reflect functional reciprocal cortical–subcortical interactions in healthy as well as clinical populations (Knyazev, ; Schutter & Knyazev, ), and it might reflect voluntary top‐down processes of executive control (including AC), mediated by (dorsolateral) PFC, over bottom‐up processes from limbic areas (such as the anterior cingulate cortex, hippocampus, and amygdala; Bishop, ; Gregoriou, Rossi, Ungerleider, & Desimone, ; Hermans, Henckens, Joels, & Fernandez, ; Knyazev, ; Schutter & Knyazev, ). Besides TBR's association with ADHD, its status as an index of AC is based on repeated observations that frontal TBR is associated with PFC‐mediated cognitive and cognitive‐emotional processes (Angelidis, Hagenaars, van Son, van der Does, & Putman, ; Angelidis, van der Does, Schakel, & Putman, ; Keune et al, ; Massar, Kenemans, & Schutter, ; Putman, van Peer, Maimari, & van der Werff, ; Putman, Verkuil, Arias‐Garcia, Pantazi, & van Schie, ; Sari, Koster, Pourtois, & Derakshan, ; Schutte, Kenemans, & Schutter, ; Schutter & Van Honk, ). PFC‐mediated cognitive control seems to play an important role in the attentional processing of threatening information (see also Mogg & Bradley, ; Shechner & Bar‐Haim, ).…”

Electroencephalography theta/beta ratio covaries with mind wandering and functional connectivity in the executive control network

“…Resting-state electroencephalography (EEG) provides measures of neural oscillatory activity in different frequency bands, such as the slow theta (4-7 Hz) and faster beta (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). Lubar 1 reported higher theta/beta ratio (TBR) in attention-deficit hyperactivity disorder (ADHD) and attention deficit disorder, which has been frequently replicated since (e.g., see Refs.…”

“…[14][15][16] TBR also correlated negatively with objectively measured AC. 17 Higher TBR has also been related to more reward-motivated decision making that requires executive reversal learning and inhibition of dominant approach−motivated behavior [18][19][20] and to lower trait anxiety, 10,14,15 also implying potential benefits of having a higher TBR. Taken together, these studies demonstrate that TBR is related to a variety of psychological functions that require prefrontal executive regulation of emotional and motivational processes that are likely subcortically mediated.…”
