In
this work, we implemented tDCS experiments on a monkey brain and a phantom at a 7T human
MRI scanner to investigate
the possibility to measure current flow during tDCS. Our results showed that
imaging distortions caused by current in lead wires but not in brain is a
possible source of BOLD-like MRI signal changes.
