A Wada test, also known as an intracarotid amobarbital procedure, is a medical procedure used to determine where the language center is located in the brain. During the test, a small amount of amobarbital is injected into one of the carotid arteries, which temporarily puts half of the brain to sleep. While the brain is asleep, the doctors can test the other half of the brain to determine language function. This is important for patients like Jill who are undergoing surgery that may affect the language center of the brain. PET scans, fMRI, and CT scans may also be used in preparation for brain surgery, but they do not specifically test for language function.
