By trial and error, reactions of coal tar compounds were found to yield useful dyes.
With the biochemical information acquired from public databases such as KEGG [ 51], MetaCyc [ 52], BRENDA [ 53], and TCDB [ 54], manual revisions including deletion of error reactions, addition of organism-specific information, checking of mass-charge balance and filling of metabolic gaps were conducted one by one.
Reduced fronto-thalamo-parietal activation that was normalized with MPH was, furthermore, negatively associated with faster post-error reaction times in patients, which were trendwise slowed with MPH.
This would be in line with the behavioral effect of MPH of modulating go and post-error reaction times, but not inhibition speed, which, furthermore were correlated with the reduced frontothalamic error-processing activation that was normalized with MPH.
There was a significant positive correlation in patients between post-error reaction times and left and right IFC activation (r =.7, p <.02) and between go reaction times and right IFC activation (r =.6, p <.05) and a negative correlation between response variability and right inferior parietal activation (r = −.7, p <.02).
All participants completed the CPT, with performance measures of omission errors, commission errors, reaction time and reaction standardization computed.
WCST: The following performance variables were considered: number of achieved categories, percentage of perseverative errors, reaction time (RT) of 2nd and 3rd trials as means of set shift (note: only RTs were included where, in fact, a set shift had taken place), and RT of 5th and 6th correct trials as means of maintaining set [ 9].
Errors were defined as commission errors (reactions to punishing stimuli), which are equivalent to perseveration errors in reversal and extinction.
Omission errors, committed errors, average reaction time and intraindividual variance of reaction time are analyzed in both subtests to estimate changes in the attention performance.
