Bromocriptine modulated the blood-oxygen-level-dependent (BOLD) signal during rule switching: rule-switching-related activity in the left posterior lateral frontal cortex and in the striatum was increased compared to placebo, at comparable performance levels.
We tested a cohort of early HD patients and presymptomatic HD gene carriers on a series of oculomotor tasks designed to measure saccade initiation, inhibition and rule switch cost.
To the best of our knowledge, a constructive way to design a switching rule, switching regions, and mean square exponential stability of switched stochastic systems with interval time-varying delay, non-differentiable time-varying delays, which are important in both theory and applications, have not been fully studied yet (see, e.g., [25 38] and the references therein).
Rushworth et al. (2002, 2005) and Ravizza and Carter (2008) proposed a distinction between attentional and intentional set switching, and perceptual and rule switching, respectively.
It should be noted that the distinction between task and source switching considered here differs from the distinction between intentional and attentional set switching proposed by Rushworth et al. (2002, 2005) or the similar distinction between rule switch and perceptual switch proposed by Ravizza and Carter (2008).
(the so-called Switching Property of the switching rule ): the switching sequence ST is defined according to the -Property: (2.3).
We don't need to pass any new laws or rules, switch any committee chairs or assignments, spend a dime of new money or wait for another election.
Close correlations have been demonstrated between this cortical cholinergic dysfunction in PDD and worsening scores on tests of working memory, rule-switching and response inhibition (Bohnen et al., 2006), all of which require a strong attentional component.
Cognitive flexibility in rule-switching tasks such as the WCST relies on the interplay of multiple cognitive processes, and impairment in any one of them might lead to a performance deficit.
