Local and remote effects of transcranial direct current stimulation on the electrical activity of the motor cortical network.

abstract：:Increased cerebral blood flow in the anterior cingulate cortex (ACC) has been noted in a range of cognitively demanding tasks studied with PET. A PET study of 10 normal males was carried out using the bolus H2(15)O intravenous injection technique to examine the effects of anticipation on blood flow to the ACC. In a se...
