==History== The Wada test is named after Japanese neurologist and epileptologist [[Juhn Atsushi Wada]], of the [[University of British Columbia]].<ref>Loring, D.W., Meador, K.J., Lee, G.P., King, D.W. (1992). Amobarbital Effects and Lateralized Brain Function: The Wada Test.

Wada developed the technique of transient hemispheric anesthetization through carotid amytal injection to decrease the cognitive side effects associated with bilateral electroconvulsive therapy.<ref>{{cite journal | author = Wada J | year = 1997 | title = Youthful Season Revisited | journal = Brain and Cognition | volume = 33 | issue = 1| pages = 7β10 | doi=10.1006/brcg.1997.0879| pmid = 9056271 | s2cid = 5530070 }}</ref> He published the initial description of motor, sensory, language, and effects on the "conscious state" in 1949, in [[Japanese language|Japanese]]. During his fellowship at the [[Montreal Neurological Institute]], he introduced the test to Dr. [[Brenda Milner]] and associates, who modified the test to assess language laterality and memory function prior to a unilateral lobectomy. As this is now the primary use of the procedure, some neuropsychologists argue for it to be renamed the Wada-Milner Test in recognition of her significant contributions.<ref>{{cite web |last1=Andrew-Gee |first1=Eric |title=Doctor Juhn Wada revolutionized epilepsy surgery (Obituary) |url=https://www.theglobeandmail.com/canada/article-doctor-juhn-wada-revolutionized-epilepsy-surgery/ |website=The Globe and Mail |access-date=29 December 2023 |date=4 May 2023}}</ref><ref>{{cite web |last1=Loring |first1=David |last2=Meador |first2=Kimford |title=History of the Wada Test |url=https://med.emory.edu/departments/neurology/_documents/loring_meador_wada_history_chapter.pdf |publisher=Oxford Handbook of History of Clinical Psychology}}</ref>
