Transcranial direct current stimulation (tDCS) induces an electrical field in the target zone of the brain, polarizing or depolarizing neurons. Actually tDCS protocols only consider current, time and sometimes current density as main variables to design therapeutic paradigms. Brain is a highly anysotropic mass and electrical fields, which are responsable of neuromodulation, are hardly calculated.
Hi Carlos,
EEG and ECoG have been previously used to monitor the response to tDCS. If you are looking for the least invasive approach see this paper for reference on scalp EEG.

Hi,
The attached paper uses MEG but may also be of interest:

Theoretically, we should be able to do it. I am looking for what is available in reality, too. If anybody has some information about any device, please let me know. Thanks.
at NUST we are working on ultra wide band antennas (arrays) to measure cortical electric field. At this stage the work is purely model based. But in future we intend to use the same concept on realistic phantoms.if someone is interested please do let me know, I will be more than happy to assist.
