Background Impulsivity is an enduring personality trait that is highly relevant for the
development of neuropsychiatric disorders. Although impulse control disorders (ICD) are …

Introduction Lower limb motor dysfunction is common in patients with stroke, and usually
caused by brain neural connectivity disorder. Previous studies have shown that the whole …

Executive dysfunction is common in Parkinson's disease (PD) patients. The catechol-O-
methyltransferase (COMT) Val158Met polymorphism has been proposed to affect executive …

The neuroanatomical and molecular substrates for cognitive impairment in Parkinson
Disease (PD) are far from clear. Evidence suggests a non-dopaminergic basis, and a crucial …

Diminished synthesis of the neurotransmitter serotonin (5-HT) has been linked to disrupted
impulse control in aversive contexts. However, the neural correlates underlying a …

The motor manifestations of Parkinson's disease (PD) are secondary to a dopamine
deficiency in the striatum. However, the degenerative process in PD is not limited to the …

Many people with Tourette syndrome are able to volitionally suppress tics, under certain
circumstances. To understand better the neural mechanisms that underlie this ability, we …

A number of repetitive transcranial magnetic stimulation (rTMS) protocols have been
developed for modulating brain function non-invasively. To identify the most powerful one …

The neural network mediating successful response inhibition mainly includes right
hemisphere activation of the pre‐supplementary motor area, inferior frontal gyrus (IFG) …

Background Response inhibition is a key neurocognitive factor contributing to impulsivity in
mood disorders. Here, we explored the common and differential alterations of neural circuits …
