This project investigates the effects of a single dose of ondansetron on brain function in healthy adults. The investigators hypothesize that there will be a dose-dependent reduction in activation of the insula and somatosensory brain regions associated with the use of ondansetron.

Inclusion Criteria: - All subjects must be medically healthy, between 18 and 60 years of age, and fluent (speaking and writing) in English Exclusion Criteria: - Present or previous diagnosis of any psychiatric disorder or major developmental disorder (autism/Asperger's disorder, pervasive developmental disorder), based on psychiatric evaluation using the Mini International Neuropsychiatric Interview (M.I.N.I.) or Structured Clinical Interview for DSM disorders (SCID) - Any disability or health problem that prevents them from completing study procedures (e.g. color blindness, severe carpal tunnel syndrome, etc.) - History of organic mental syndromes, head trauma, migraines, seizures, other CNS neurological disease, recent use of illegal drugs or current substance dependence, or significant medical illness other than that listed above (by self-report) - Pregnant or nursing women - Subjects with a medical condition or other predisposition that increases the risk of adverse effects when taking ondansetron. These include individuals with drug allergies or known hypersensitivity to ondansetron (or other 5-HT3 antagonists), heart disease, congestive heart failure, heart rhythm disorder, congenital long QT syndrome, electrolyte abnormalities (e.g., hypokalemia, hypomagnesemia) or hepatic impairment - Subjects who report taking apomorphine will be excluded - Subjects with abnormal EKG will either be excluded from participation, or referred to a cardiologist for further assessment of eligibility - Subjects with abnormal liver function or electrolytes (as determined by blood test) will be excluded from participation if a study team physician determines it is unsafe for them to participate - Cross-reactivity with other 5-HT3 antagonists has been reported, so any individual taking a 5-HT3 antagonist will be excluded |

Primary | BOLD signal in the insula and somatosensory cortex measured by fMRI | On Day1, Functional magnetic resonance imaging (fMRI) will be done 90 minutes after drug or placebo ingestion to measure the blood oxygen level dependent (BOLD) signal in insula and somatosensory cortex. | Day 1 | |
Primary | BOLD signal in the insula and somatosensory cortex measured by fMRI | At week 1, fMRI will be done 90 minutes after drug or placebo ingestion to measure the BOLD signal in insula and somatosensory cortex. | 1 week | |
Secondary | BOLD signal in the whole brain measured by fMRI | On Day1, fMRI will be done 90 minutes after drug or placebo ingestion to measure the BOLD signal across the whole brain. | Day 1 | |
Secondary | BOLD signal in the whole brain measured by fMRI | At week 1, fMRI will be done 90 minutes after drug or placebo ingestion to measure the BOLD signal across the whole brain. | 1 week |
