Modulation of Cognitive Flexibility by Transcranial Direct Current Stimulation, Tyrosine Administration and Polymorphisms in the COMT Gene
Mod of Cognitive Flexibility by tDCS, Tyrosine Polymorphisms in the COMT Gene
The current study would examine whether increases in endogenous dopaminergic activity via tyrosine and the (presumed) excitation of these by anodal tDCS of the dlPFC could causally be related to cognitive flexibility as measured…

Nicotine Dependence
Association of Functional COMT Val108/Met Polymorphism With Smoking Cessation in Nicotine Replacement Therapy
Nicotine replacement treatment (NRT) can be efficacious for smoking cessation, but used by only a minority of smokers in China. Pharmacogenetic matching may improve treatment outcomes for NRT in subgroups of smokers.
