چکیده (انگلیسی):

In recent years there has been an exponential rise in the
number of studies employing transcranial direct current
stimulation (tDCS) as a means of gaining a systems-level
understanding of the cortical substrates underlying behaviour.
These advances have allowed inferences to be
made regarding the neural operations that shape perception,
cognition, and action. Here we summarise how
tDCS works, and show how research using this technique
is expanding our understanding of the neural basis
of cognitive and motor training. We also explain how
oscillatory tDCS can elucidate the role of fluctuations in
neural activity, in both frequency and phase, in perception,
learning, and memory. Finally, we highlight some
key methodological issues for tDCS and suggest how
these can be addressed.
