Recruitment & Eligibility

Status: ot yet recruiting

Sex: All

Target Recruitment: 33

Inclusion Criteria

•Are aged between 18 and 50 years. The upper age limit of 50 years has been chosen based on evidence suggesting the onset of very mild cognitive decline may begin past this age.
•Engage in regular cardiovascular activities (e.g., at least twice a week).
•Agree to fast for 3 hours prior to testing (only water or herbal tea is allowed). This is because glucose levels are known to modulate performance in several cognitive domains. By having all participants fast for 3 hours prior to testing, we aim to control for any potential enhancing effects of glucose on executive function.

Exclusion Criteria

Participants will not be able to participate if they:
•Suffer from cardiac, hepatic, renal, and/or neurological disorders.
•Have damaged or diseased skin on your face and scalp or have a sensitive scalp.
•Have a history of alcohol or drug addiction, or severe psychiatric illness.
•Are receiving drug treatment known to lower the seizure threshold (e.g., treatments for epilepsy).
•Are pregnant.
•Are sleep deprived, meaning you have slept less than 6 hours the night before testing.
•Have metallic dental fillings, orthodontic appliances, a cardiac pacemaker, cochlear implant, and/or surgical clips in your body.
•Have a medical history of migraine or frequent headaches.
