The Wada Test

The intra-carotid amobarbital "Wada" test is performed primarily on epilepsy surgical candidates to determine on which side of the brain speech, memory, and motor functions reside. The Wada is used to decide whether a patient can be sedated during brain surgery or must remain awake in order to have cognitive testing. Cognitive testing pinpoints the precise areas of the brain associated with speech and memory.
