“…Here we approach these challenges through the variability of neural activity, which has been hypothesized to enable the formation of the connectome 5,6,8,29,37 , and which is increasingly recognized to carry important functional links to age and behavior 30,31,[38][39][40] . Using timeresolved complexity estimation of resting-state BOLD signals, we uncover the universal phenomenon of "complexity drops" that represent spontaneous episodes of increased pattern regularity in the brain.…”

“…Lastly, we turn to the behavioral implications of our findings, given that the variability of neural activity is increasingly recognized to be functionally relevant [29][30][31][38][39][40][51][52][53] . Even over the narrow range of early adulthood, complexity dynamics were highly sensitive to age and reflected inter-individual differences in cognition and motor performance, suggesting that an increased capacity for complexity drops represents a beneficial functional profile of the brain.…”

“…This study took an individual differences approach, relating individual differences in behavior (i.e, individual DRB effects in RT and accuracy) to individual differences in neural oscillations (i.e., individual postmovement beta ERS effects). Neural variability both within and between subjects is considered a key dimension for understanding brain-behavior correlations ( Waschke, Kloosterman, Obleser, & Garrett, 2021). Theoretically, individual (DRB and beta ERS) effects in within-subject designs are composed of mean group effects, meaningful individual deviations from the mean group effect, and measurement error (see Seghier & Price, 2018).…”

“…M. Churchland & Abbott, 2012;Deco & Hugues, 2012;Goris et al, 2014;Shadlen & Newsome, 1998). In particular, neural response variability is believed to change during development and to be correlated with behavioral performance, stimuli conditions and to vary across different neural states (Lombardo et al, 2018;McIntosh et al, 2008;Mišić et al, 2010;Voytek et al, 2015;Waschke et al, 2021). Several studies have shown that spike count variability changes across different conditions in several cortical, subcortical, and cerebellar regions (A. K. Churchland et al, 2011;M.…”
