“…In a subsequent study conducted by the same research group , only right-sided parietal activity in the β2 (13-30 Hz) frequency range was a significant predictor of decreased AC. In any case, in both studies Morillas-Romero et al, 2013), results regarding the role of the parietal cortex fit with previous literature claiming that this brain area is critically involved in attentional capabilities (Kanai et al, 2011;Mevorach et al, 2009;Ochner et al, 2009;Posner and Rothbart, 2009) and processes (Deiber et al, 2007;McRae et al, 2010;Schutter et al, 2001;Szczepanski and Kastner, 2013) which, in turn, seem to be crucial to regulate emotions.…”

“…Importantly, this asymmetry was also found at the brain level in the rTPJ where a greater congruity effect on brain activation was found for the numerical condition compared with the nonnumerical condition. The rTPJ has been suggested to have the role of a "circuit breaker" during top-down attention (Corbetta, Patel, & Shulman, 2008;Corbetta & Shulman, 2002), biasing attention based on the relative saliency of the stimuli (Mevorach, Humphreys, & Shalev, 2009). For example, if a fire alarm were to sound while concentrating on a top-down, goaldirected task, like reading these lines, the rTPJ will be activated to redeploy the attention from the goal-directed task (i.e., reading) to stimulus-driven action (i.e., listening to the alarm).…”

It is well established that, when comparing nonsymbolic magnitudes (e.g., dot arrays), adults can use both numerical (i.e., the number of items) and nonnumerical (density, total surface areas, etc.) magnitudes. It is less clear which of these magnitudes is more salient or processed more automatically. In this fMRI study, we used a nonsymbolic comparison task to ask if different brain areas are responsible for the automatic processing of numerical and nonnumerical magnitudes, when participants were instructed to attend to either the numerical or the nonnumerical magnitudes of the same stimuli. An interaction of task (numerical vs. nonnumerical) and congruity (congruent vs. incongruent) was found in the right TPJ. Specifically, this brain region was more strongly activated during numerical processing when the nonnumerical magnitudes were negatively correlated with numerosity (incongruent trials). In contrast, such an interference effect was not evident during nonnumerical processing when the task-irrelevant numerical magnitude was incongruent. In view of the role of the right TPJ in the control of stimulus-driven attention, we argue that these data demonstrate that the processing of nonnumerical magnitudes is more automatic than that of numerical magnitudes and that, therefore, the influence of numerical and nonnumerical variables on each other is asymmetrical.

“…In this sense, the study of potential physiological correlates that are associated with both state and trait AC, such as EEG SW/FW ratio and coupling measures, could shed light on the topic. Moreover, we decided also to include EEG recordings of parietal areas, in addition to recordings at frontal electrodes, because the parietal cortex has also been recognized as playing a relevant role in attentional and executive control functioning (e.g., Balle et al, 2013;Kanai, Dong, Bahrami, & Rees, 2011;Mevorach, Humphreys, & Shalev, 2006;Mevorach, Humphreys, & Shalev, 2009;MorillasRomero, Tortella-Feliu, Bornas, & Aguayo-Siquier, 2013;Posner, Rueda, & Kanske, 2007).…”

Relationships between electroencephalographic (EEG) slow-and fast-wave frequency bands are considered to be of interest in the study of dispositional affective traits, emotion regulation, and attentional phenomena. However, to date, no previous studies had explored whether both state performance-based and self-reported attentional control (AC) measures potentially relate to different patterns of spontaneous EEG measures, in the absence of emotional stimuli. In the present study, individual differences in spontaneous EEG theta/beta ratio and delta-beta coupling at frontal and parietal sites were explored in a sample of 110 healthy volunteers as potential correlates of individual differences in performancebased attentional network functioning, as measured through the Attentional Network Test for Interactions (ANT-I) and self-reported AC. We found that stronger delta-beta coupling at parietal sites was associated with higher self-reported AC. However, no significant associations were found between executive control network functioning and the EEG ratio or coupling measures. Furthermore, a lower spontaneous frontoparietal theta/beta ratio was found to be associated with better orienting network functioning. These results are discussed with a focus on the potential utility of spontaneous EEG measures in several cortical regions for capturing trait-like individual differences in temperament-related factors.Keywords Spontaneous EEG . Theta/beta ratio . Delta-beta coupling . Attentional network functioning . Attentional control Relationships between spontaneous electroencephalographic (EEG) slow-wave (SW; i.e., the theta 4-7 Hz, delta 1-3 Hz bands) and fast-wave (FW; i.e., the beta 13-30 Hz band) frequency band activity may reflect the cortical-subcortical interactions involved in affective processes (Knyazev, 2007) and are considered to be of interest in the study of emotional states, dispositional affective traits, emotion regulation, and related processes and capabilities (e.g., Arns, Conners, & Kraemer, 2013;Massar, Kenemans, & Schutter, 2014;Putman, Arias-Garcia, Pantazi, & van Schie, 2012;Schutter & Knyazev, 2012;Schutter & Van Honk, 2005a;van Peer, Roelofs, & Spinhoven, 2008;Velikova et al., 2010).Two often-used EEG indices are the SW/FW ratio and SW-FW coupling. The SW/FW ratio results from dividing the SW power density (i.e., theta) by the FW power density (i.e., beta) for each individual participant's EEG recording at a selected brain site or selected sites, with higher ratio scores reflecting relatively more SW than FW power. It has been postulated that a relative predominance of SW over FW power may reflect reduced cortical control function over subcortical drives related to motivational imbalances (Schutter & Van Honk, 2005a). On the other hand, SW-FW coupling (usually delta-beta coupling) is operationalized as the positive correlation between SW and FW in a selected sample, which usually compares samples that have scored high or low on a criterion variable (e.g., trait anxiety; see Putman et al., ...
