Dual Site-Dual Channel Non-invasive Brain Stimulation for Language and Cognitive Function in Healthy Subjects

Effect of Dual Site-Dual Channel Non-invasive Brain Stimulation for Recovery of Language and Cognitive Function in Healthy Subjects

The aim of this study is to investigate the effect of dual site-dual channel non-invasive brain stimulation for recovery of language and cognitive function in healthy. Simultaneous dual site-dual channel stimulation was applied by using two sets of transcranial direct current stimulation devices. All subjects will go through four conditions of transcranial direct current stimulation with for 30 minutes. Four conditions are 1) Dual stimulation: i) anodal stimulation on left inferior frontal cortex, ii) anodal stimulation on left dorsolateral prefrontal cortex. 2) IFG stimulation: anodal stimulation on left inferior frontal cortex; 3) DLPFC stimulation: anodal stimulation on left dorsolateral prefrontal cortex area. 4) sham stimulation

Inclusion Criteria:

• healthy subjects with age over 19 years old

Exclusion Criteria:

• history of disorders involving central nervous system
• patients with severe medical or psychiatric disease
