non-invasive transcranial electrical stimulation (tES) provides us with the opportunity to study the influence of neuronal modulations on cognitive processes
transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), or transcranial random noise stimulation (tRNS) can be applied via electrodes attached to the scalp
this non-invasive brain stimulation allows us to modulate the cortical excitability of the stimulated brain regions
Lab equipment:
4-channel DC stimulator (version MC) from NeuroConn (approved as a medical product in Germany)
bi-polar stimulation, sinusoidal stimulation up to 250Hz
current selectable up to 4.5 mA
stimulation duration up to 30 min
controlled by a panel PC (1.6 GHz)
the validation of current flow directions and stimulation of underlying brain regions can be simulated using simulation software (e.g., HD-Explore (Sosterix medical) or SimNIBS)
