Publisher Summary Achieving short-or even long-term neuroplastic functional modifications
of cortical networks through the modulation of activity and excitability of neuronal ensembles
has been the focus of many research activities in the last decades. The application of weak
direct currents has been shown to elicit cortical excitability and activity shifts during, and after
the end of stimulation in animals and humans, and thus could evolve as a promising
technique in this field of research. In animals, intracortical or epidural electrodes have been …
