Hvidovre Hospital is looking for participants for a new project, which seeks to evaluate the efficacy of widely used non-invasive brain stimulation modality, transcranial alternating current stimulation, using a more systematic approach in larger scalp area. The study is harmless and safe.
You can participate if you:

• are from 18 to 39 years old
• have normal or corrected-to-normal vision
• have the ability to give written or oral informed consent.

You cannot participate if you:

• Have self-reported pregnancy or are breastfeeding. Any subject with the potential to become pregnant must ensure against this (e.g. by taking oral contraceptives, or other high efficacy method).
• Have self-reported medical conditions that may interfere with the study (e.g., epilepsy, heart disease).
• Have previously been diagnosed a neurological or psychiatric condition.
• Use medication which may have cognitive effects (e.g., stimulants, antidepressants, neuroleptics).
• Have severe scalp skin lesions (i.e., razor nicks, wounds that have not healed, recent scare tissue, broken skin, etc.).
• Have had previous craniotomy or other acute neurosurgical interventions.
• Have claustrophobia, pacemakers, implanted electronic devices, metal in the body (e.g., pacemaker, deep brain stimulator, cochlear implant), or other contraindications for MR scans.
• Have an alcohol intake exceeding 28 units per week, smoking more than 20 cigarettes per day.
• Use illicit substances in the week prior to the experimental session.
• If you don’t wish to be informed about incidental health findings from the MRI.
