The serotonergic precursor tryptophan and the dopaminergic precursor tyrosine have been
shown to be important modulators of mood, behaviour and cognition. Specifically, research …

Cortico-basal ganglia circuits are thought to play a crucial role in the selection and control of
motor behaviors and have also been implicated in the processing of motivational content …

Background Recent evidence suggests that transcranial direct current stimulation (tDCS)
may interact with the dopaminergic system to affect cognitive flexibility …

Molecular and functional imaging techniques have been used and combined with
pharmacological probes to evaluate the role of dopamine in impulsivity. Overall, strong …

Increasing evidence, particularly from animal studies, suggests that dopamine and GABA
are important modulators of cognitive flexibility. In humans, increasing dopamine synthesis …

The creativity impairment under acute stress may be closely related to the down-regulation
of the prefrontal cortex function caused by stress-related neurotransmitters and hormones. In …

Objective The current study aimed to investigate the impact of transcranial alternating
current stimulation (tACS) on working memory and selective attention in athletes with …

Transcranial direct current stimulation (tDCS) can sometimes cause the opposite of its
intended effect. These reverse effects may be related in part to individual differences in …

Background Gait disturbances are exacerbated in people with Parkinson's disease (PD)
during dual-task walking (DTW). Transcranial direct current stimulation (tDCS) has been …

This study aimed to investigate the moderating role of aerobic fitness on the effect of acute
exercise on improving executive function from both behavioral and cerebral aspects. Thirty …
