Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Adult subjects (18-30 years of age) with no history of neurological disorder/disease and no counter-indications to MRI will be included in this study. All participants will be right-handed native Dutch speakers with normal vision or contact lenses.

Exclusion criteria

Exclusion criteria: The participants have to be able to breath without problems through each nostril. Potential participants will be prescreened for contra-indications for fMRI, which include metal implants, heart arrhythmia, claustrophobia, and possible pregnancy (in adult females). They will additionally be prescreened for head trauma, premature birth, learning disabilities, and history of neurological or psychiatric illness and/or use of psychotropic medications. Finally, left-handed individuals will be excluded from the study because some left-handers have substantially different brain organization relative to right-handers.
