Discerning measures of conscious brain processes associated with superior early motor performance: Capacity, coactivation, and character

All talk? Challenging the use of left-temporal EEG alpha oscillations as valid measures of verbal processing and conscious motor control

“…As such, it also becomes difficult to interpret our finding that T8-Fz connectivity was significantly higher than T7-Fz connectivity for all conditions across the majority of our task phases. Previously, researchers have inferred the involvement of visuospatial processes in motor performance from T8-Fz connectivity (Bellomo et al, 2018;Cooke, 2013;van Duijn, Buszard, Hoskens, & Masters, 2017). It could therefore be argued that this observed hemispheric asymmetry reflects the obvious visuospatial component of our reaching and grasping task.…”

EEG correlates of verbal and conscious processing of motor control in sport and human movement: a systematic review

“…Three studies measured pre-post changes in T7-Fz connectivity after extended practice, reporting a steady increase in a golf putting task (Gallicchio, 2017), a significant decrease in a pursuit tracking motor skill (Ghasemian et al, 2017), and no change in a sequential finger tapping task (Zhu et al, 2010). Of the five studies that examined performance accuracy, two found lower T7-Fz connectivity for more accurate performance (Cheng et al, 2017;, and three found no difference between accurate and inaccurate performances (Dyke et al, 2014;Hunt et al, 2013;van Duijn et al, 2017). One study experimentally decreased T7-Fz using pre-performance hand contractions, but this had no significant effect on performance or kinematics (Hoskens et al, 2020).…”

“…Six studies examined whether the propensity to reinvest in conscious control processes could affect left-temporal-frontal connectivity. These studies reported no differences between high and low reinvestors (Chu & Wong, 2019;Ellmers et al, 2016), no correlation between MSRS scores and T7-Fz connectivity (Chow et al, 2019;van Duijn et al, 2017), higher MSRS scores to be associated with less change in T7-Fz connectivity during postural threat (Chan et al, 2019), and high reinvestors to exhibit greater T7-Fz connectivity compared to low reinvestors in golf putting (Zhu et al, 2011a, exp 1). One study found that larger verbal working memory scores were associated with increased T7-F3 connectivity (Buszard et al, 2016).…”

Investigating Changes in Real-time Conscious Postural Processing by Older Adults during Different Stance Positions Using Electroencephalography Coherence

“…Previous studies using EEG suggested that conscious processing during motor performance is associated with coherence between the verbal-analytical (T3) 1 and motor planning (Fz) regions of the brain (Chow, Ellmers, Mak, Young, & Wong, 2019;Chu & Wong, 2018;Deeny, Hillman, Janelle, & Hatfield, 2003;Gallicchio, Cooke, & Ring, 2016;Hatfield, Landers, & Ray, 1984;van Dujin, Buszard, Hoskens, & Masters, 2017;; but see Bellomo, Cooke, & Hardy, 2018, who found power to be more sensitive to verbal analytical processing than coherence). High coherence implies highly synchronized communication between two regions, with low coherence indicating the opposite (Weiss & Mueller, 2003).…”
