“…Future studies could also explore how neural variability quenching and boosting in different timescales are related to various aspects of decision making such as perceptual sensitivity and different kinds of biases ( Fleming et al, 2010 ; Talluri et al, 2018 ; Urai et al, 2019 ), as well as to confidence and metacognitive processes ( Fleming and Dolan, 2012 ; Yeung and Summerfield, 2012 ). Furthermore, individual decision bias has also been linked to the magnitude of transient dilations of the pupil ( de Gee et al, 2017 , de Gee et al, 2014 ) and to entropy of EEG ( Waschke et al, 2019 ), suggesting that pupil-linked neuromodulation ( Joshi and Gold, 2020 ) could be related to decision bias through adjustments to moment-to-moment neural variability. Further investigation of such relationships could yield fruitful insights about the neurochemical mechanisms underlying associations between neural variability and higher order cognitive function ( Alavash et al, 2018 ; Garrett et al, 2015 ).…”
