“…Then, the time interval was cue-locked from −500 ms to 1,000 ms around cue onset, and the alpha modulation index (MI) from cue-locked data was used to investigate the cue-elicited modulation in the alpha band (8-12 Hz). The degree of lateralization for alpha band power was defined by using the formula (Vollebregt et al, 2015) hemisphere. Note that the contralateral waveform for the target was the average of the left-hemisphere electrode when the target was in the right visual field and the right-hemisphere electrode when the target was in the left visual field.…”

In covert visual attention, one fundamental question is how advance knowledge facilitates subsequent neural processing and behavioral performance. In this study, with a rapid event‐related simultaneous electroencephalography (EEG) and functional near infrared spectroscopy recording in humans, we explored the potential contribution of anticipatory electrophysiological activation and hemodynamic activation by examining how anticipatory low‐frequency oscillations and changes in oxygenated hemoglobin (HbO) concentration influence the subsequent event‐related potential (ERP) marker of attentional selection. We found that expecting a target led to both a posterior lateralization of alpha‐band (8–12 Hz) oscillation power and a lateralization of HbO response over the visual cortex. Importantly, the magnitude of cue‐induced alpha lateralization was positively correlated with the nearby HbO lateralization in the visual cortex, and such a cue‐induced alpha lateralization predicted the subsequent target‐evoked N2pc amplitudes assumed to reflect attentional selection. Our results suggest that each individual's attentional selection biomarker as reflected by N2pc is predictable in advance via the anticipation‐induced alpha lateralization, and such cue‐induced alpha lateralization seems to play an important role in the functional coupling effects between the low‐frequency EEG and the nearby hemodynamic activation.

“…Suppressive modulation, or event‐related desynchronization (ERD) of alpha, then, reflects cortical activation. In hemi‐field sensory attentional contexts, cortical hemispheric lateralization of alpha ERD corresponds to lateralization of attentional deployment (Blacker, Ikkai, Lakshmanan, Ewen, & Courtney, ; Ikkai, Blacker, Lakshmanan, Ewen, & Courtney, ; Vollebregt et al, ). Children with ADHD have shown an impaired ability to modulate alpha ERD asymmetrically, with corresponding deficits in lateralized attention (ter Huurne et al, ).…”

Children with ADHD show developmentally abnormal levels of mirror overflowunintentional movements occurring symmetrically opposite of intentional movements. Because mirror overflow correlates with ADHD behavioral symptoms, the study of disinhibition in motor control may shed light on physiologic mechanisms underlying impaired behavioral/cognitive control. This is a case-controlled study of EEG recording from 25 children with ADHD and 25 typically developing (TD) controls performing unilateral sequential finger tapping, with overflow movements measured using electronic goniometers. Consistent with previously published findings, children with ADHD showed increased mirror overflow as compared with TD peers. EEG findings revealed less lateralized alpha modulation (event-related desynchronization; ERD) and decreased magnitude of beta ERD in ADHD; both alpha and beta ERD reflect cortical activation. Moderation analysis revealed a significant association between beta ERD and overflow, independent of diagnosis; and an equivocal (p = .08) effect of diagnosis on the relationship between alpha ERD and overflow, with a significant effect in children with ADHD but not TD children. These results suggest two mechanisms involved with mirror overflow: one reflected in beta ipsilateral to the intentional movement and relevant to both children with ADHD and controls, and the other seemingly more specific to ADHD (alpha, contralateral to movement).

“…Thus, the increase of alpha activity is considered as reflecting system-level inhibition in the brain while the suppression of alpha activity is considered as a release from inhibition or the allocation of attention to relevant aspects of a task (Klimesch, 2012). This phenomenon has been successfully used to point to neural mechanisms underlying anticipatory visual attention in general (Jensen and Mazaheri, 2010;Vollebregt et al, 2015) and to changed attentional capacity in attention deficit disorder (Vollebregt et al, 2016). This visuospatial covert attention paradigm may offer a sensitive enough measure to demonstrate changes in attentional resources related to variance in the level of PA or AF.…”

Underlying brain processes of exercise-related benefits on executive functions and the specific contribution of physical activity vs. aerobic fitness are poorly understood, especially during adolescence. We explored whether and how physical activity and aerobic fitness are associated with selective attention and the oscillatory dynamics induced by an anticipatory spatial cue. Further, we studied whether the link between physical exercise level and cognitive control in adolescents is mediated by the task-related oscillatory activity. Magnetoencephalographic alpha oscillations during a modified Posner’s cueing paradigm were measured in 59 adolescents (37 females and 22 males, 12 to 17 years). Accelerometer-measured physical activity and aerobic fitness (20-m shuttle run test) were used to divide the sample into higher and lower performing groups. The interhemispheric alpha asymmetry during selective attention was larger in the high than in the low physical activity group, but there was no difference between the high and low aerobic fitness groups. Exploratory mediation analysis suggested that anticipatory interhemispheric asymmetry mediates the association between physical activity status and drift rate in the selective attention task. Higher physical activity was related to increased cue-induced asymmetry, which in turn was associated with less efficient processing of information. Behaviorally, higher physically active males showed stronger dependence on the cue while higher fit females showed more efficient processing of information. Our findings suggest that physical activity may be associated with a neural marker of anticipatory attention in adolescents. These findings have implications for understanding the varying results on the association between physical activity and attention in adolescents.HIGHLIGHTSPhysical activity and aerobic fitness link differently with attention in adolescents.Higher physical activity relates with stronger cue-induced oscillatory asymmetry.Brain hemispheric interaction mediates the link between physical activity and attention.
