However, as noted earlier, the WCST has been associated with left frontal activity [9], right frontal activation [8], and bilateral frontal activation [7].
Alternatively, competition for frontal "workspace" might be stronger than in parietal cortex [13], correlating to stronger modulation of frontal activity as compared to parietal activation.
The frontal activity vanishes briefly at about 500 ms after valve activation and reappears between 500 and 700 ms with a medial maximum (see Supplementary Material, Video S2).
We showed that while self- and other-face processing involve virtually overlapping right frontal activity in TD children, children with ASD only exhibit such activation when viewing their own faces.
Most of the precipitation results from atmospheric frontal activity, though some is a result of convection or condensation.
Three of these four patients showed no left frontal activity by completion of treatment, indicating that right posterior lateral frontal activity supported category-member generation.
Results were indicative of a relative increase of right frontal activity with cortisol.
This is likely a result of the dearth of tests that are associated with right frontal activity.
During the later 550-to 900-ms time period, right inferior parietal and bilateral inferior frontal activity was again observed for moving sounds, whereas strong bilateral superior frontal activity was seen in the case of stationary sounds.
Patients who improved in treatment showed no difference in lateralization of lateral frontal activity from normal controls pre-treatment, but post-treatment, their lateral frontal activity during category-member generation was significantly more right lateralized than that of controls.
A number of studies have identified that frontal activity is related to approach and withdraw behaviors and increased responsiveness to valenced affective stimuli [39, 41, 42, 43].
