Cortical thickness correlates with impulsiveness in healthy adults

Right frontal stroke: extra-frontal lesions, executive functioning and impulsive behaviour

“…These results are consistent with an earlier study suggesting that structures outside the frontal region, such as the right inferior temporal gyrus are involved in planning and control of impulsivity (Schilling et al 2012). It seems that impulsivity in extrafrontal lesions individuals influences performance on tasks requiring EF or inhibitory control, particularly at the cognitive level.…”

“…Along with the superior frontal gyrus (SFG) and the orbitofrontal region, MFG seem to be involved in mediating inhibitory behaviour after RH stroke , and in planned actions and attention (Schilling et al 2012). The similarity of rates of errors of omission and commission when switching from one trial type to another on the Go/No-Go Task suggests that there were no behaviour alteration arising from the change from the trials and suggests that the results do not arise from variables that may interfere in go/no-go performance, as fatigue, for example.…”

Fiber connectivity between the striatum and cortical and subcortical regions is associated with temperaments in Chinese males

“…Brain anatomical studies found that NS was correlated with white matter volume in the frontal cortex, and gray matter volume in the frontal cortex and PCC (Gardini et al, 2009;Van Schuerbeek et al, 2011), and cortical thickness of the OFC, superior frontal gyrus and left middle frontal gyrus (Schilling et al, 2012). Functionally, patients with lesions centered in either the OFC or lPFC showed reduction of the frontal P3 response to novel stimuli compared to controls (Lovstad et al, 2011).…”

Relationship between trait impulsivity and cortical volume, thickness and surface area in male cocaine users and non-drug using controls

“…Unfortunately, only few VBM studies directly investigated the relation between cortical morphometry and trait impulsivity in cocaine users and controls. These studies reported a positive correlation between trait impulsivity and the volume of the prefrontal cortex in cocaine users (Crunelle et al, 2014;Ersche et al, 2011;Moreno-López et al, 2012) but a negative correlation in controls (Matsuo et al, 2009;MorenoLópez et al, 2012;Schilling et al, 2012). These studies also reported a negative correlation between trait impulsivity and the volume of the insula and temporal cortex in cocaine users (Ersche et al, 2011;Moreno-López et al, 2012) but a positive correlation in controls (Cho et al, 2013;Moreno-López et al, 2012).…”
