There is now compelling evidence that motor imagery (MI) and actual movement share
common neural substrate. However, the question of how MI inhibits the transmission of …

Heightened impulsivity and inefficient inhibitory control are increasingly recognized as risk
factors for unhealthy eating and obesity but the underlying processes are not fully …

Diffusion weighted imaging (DWI) studies in humans have shown that seniors exhibit
reduced white matter integrity compared with young adults, with the most pronounced …

The subthalamic nucleus (STN) is a small but vitally important structure in the basal ganglia.
Because of its small volume, and its localization in the basal ganglia, the STN can best be …

Background Cognitive control refers to the ability to selectively attend and respond to task-
relevant events while resisting interference from distracting stimuli or prepotent automatic …

Background Impulsivity is a hallmark of problem gambling. However, impulsivity is not a
unitary construct and this study investigated the relationship between problem gambling …

Stopping an initiated response is an essential function, investigated in many studies with
go/no-go and stop-signal paradigms. These standard tests require rapid action cancellation …

Goal-oriented signals from the prefrontal cortex gate the selection of appropriate actions in
the basal ganglia. Key nodes within this fronto-basal ganglia action regulation network are …

Less supervision by the executive system after disruption of the right prefrontal cortex leads
to increased risk taking in gambling because superficially attractive—but risky—choices are …

Rapidly stopping action engages a network in the brain including the right
presupplementary motor area (preSMA), the right inferior frontal gyrus, and the basal …
