What the study is about

This study is to find out whether and how a type of non-invasive electrical brain stimulation called transcranial electrical stimulation with temporal interference (TES-TI) can temporarily change brain activity in healthy adults. A structural MRI scan will be used to customize where the stimulation electrodes are placed for each participant to deliver TES-TI during three afternoon sessions at rest with eyes closed. Brain activity is recorded with high-density EEG. Up to 24 participants will be enrolled and on study for 3 to 12 weeks.

Being studied: TES-TI with hdEEG

Conditions: Transcranial Electric Stimulation

Inclusion Criteria

  • Medically healthy (based on self-report and study team review)
  • U.S. citizen or holding permanent resident status
  • English-speaking (able to provide consent and complete questionnaires)

Exclusion Criteria

  • Current or past history of clinically significant neurological disorder or acquired neurological disease (e.g., stroke, traumatic brain injury), including intracranial lesions (including clinically significant findings identified on the structural MRI)
  • History of inpatient psychiatric hospitalization
  • History of head trauma resulting in prolonged loss of consciousness; or a history of >3 grade I concussions
  • Current poorly controlled headaches, including intractable or frequent migraines
  • Any systemic illness or unstable medical condition that may cause a medical emergency in case of a provoked seizure (cardiac malformation, cardiac dysrhythmia, asthma, etc.)
  • History of seizures, diagnosis of epilepsy, history of abnormal (epileptiform) EEG, or family history of treatment resistant epilepsy except for a single seizure of benign etiology (e.g. febrile seizures) in the judgment of a board-certified neurologist
  • Possible pregnancy or plan to become pregnant in the next 6 months (self reported)
  • Any metal in the head or body
  • Any medical devices or implants (i.e. cardiac pacemaker, medication infusion pump, cochlear implant, vagal nerve stimulator)
  • Dental implants
  • Permanent retainers
  • Any hair braid, dreadlocks, hair pieces, or extensions which cannot be taken out before the study sessions
  • Any head coverings or headdress that participant feels uncomfortable removing for the purposes of study sessions
  • Current use of medications known to substantially lower seizure threshold, specifically chlorpromazine, clozapine, bupropion, clomipramine, or maprotiline; or other medications at doses known to substantially lower seizure threshold in the judgment of the PI
  • Active scalp lesions, broken skin, or skin conditions at planned electrode sites that would preclude safe electrode application
  • Claustrophobia (a fear of small or closed places)
  • Back problems that would prevent lying flat for up to two hours
