Impact of tDCS on Cerebral Autoregulation

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01865604
Recruitment Status : Completed
First Posted : May 31, 2013
Last Update Posted : March 16, 2016

Brief Summary:
The aim of the study is to investigate whether there is a polarity-specific influence of tDCS on cerebral vasomotor reactivity monitored by transcranial doppler sonography.
