Apparently, different pontine neuronal groups may underlay the executive process of sequencing movement segments and of computing their direction, in parallel to the separate cortical fields that manage executive functionality, as opposed to visuo-motor transformations.
Adding the change score for the executive process of selective attention and conflict resolution to the model resulted in an R-square change of 7.5% and significantly improved the regression model (F Change = 11.6, P = 0.001).
An important clinical implication of these results is that clinicians may need to consider the specific executive process of selective attention and conflict resolution and falls-related self-efficacy in the rehabilitation of gait among community-dwelling seniors.
Since these discrepant results could be due to the paradigms used (subtraction designs), recent results obtained with conjunction and interaction analyses are presented, which confirm the role of parietal areas in executive functioning and also demonstrate the existence of some specificity in the neural substrates of the executive processes of updating, shifting and inhibition.
Our study highlights the specific executive processes of set shifting and working memory were independently associated with QALYs -- a measure of health related quality of life.
Although we have so far stressed the differences between the executive processes of attentional control and reward-based behaviour, it is clear that these two processes must operate together when the appropriate cognitive set depends on reward or reward expectation.
Our multivariate linear regression model demonstrated the specific executive processes of set shifting and working memory, as measured by Trail Making Test (Part B) and Digits Verbal Span Backward Test (p < 0.01) respectively, were independently associated with QALYs after accounting for age, comorbidities, general mobility, and global cognition.
Therefore, ERP features in conflicting process were similar with those in deceptive process; the cue-target procedure was more consistent with the real deceptive procedure, while the target-cue procedure in measuring deception served as an executive process in the minds of the participants.
It has also been suggested that the lateral PFC is organized as a cascade of executive processes from a representation of simple stimulus response mappings in premotor cortex to a representation of the overarching task context in the anterior PFC (Koechlin et al. 1999, 2000, 2001, 2003).
In these experiments, we use counter switching and response inhibition tasks to examine the neural underpinnings of two cognitive processes that have often been identified as potential executive processes: the switching of attention between tasks, and the resolution of interference between competing task responses.
Interestingly, MPX, in addition, showed a drug-specific upregulation effect during the executive go process of the task in key regions for response selection and motor execution in ACC/SMA, left premotor cortex, and basal ganglia (Haber 2003).
