[[Pierre Flourens]], a French experimental psychologist, challenged the localizationist view by using animal experiments.{{sfn|Kosslyn|Andersen|1995|p={{pn|date=March 2025}}}} He discovered that removing the [[cerebellum]] (brain) in rabbits and pigeons affected their sense of muscular coordination, and that all cognitive functions were disrupted in pigeons when the [[cerebral hemisphere]]s were removed.
