What is tDCS?
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that modulates neuronal activity.
How is electrode placement determined?
Electrode placement is determined by measuring the subject's head circumference and following specific montage guidelines.
What materials are needed for tDCS?
Basic materials include pre-saturated electrodes, headgear, and a tDCS device.
Is consent required for tDCS studies?
Yes, informed consent must be obtained from participants before starting the tDCS session.
What should be checked before starting tDCS?
Ensure all equipment is connected properly, the subject is comfortable, and impedance is within acceptable limits.
What sensations might participants feel during tDCS?
Participants may experience tingling or itching sensations under the electrodes, which usually fade after a short period.
