Quizplus · Accepted Answer

The decision to fly in this scenario is made by interneurons in the ganglia, not the brain, as the behavior persists even when the fly's head (and thus its brain) has been removed. This indicates that the control mechanism for this behavior is located in the fly's body, specifically in the ganglia, which are clusters of nerve cells that process sensory input and control motor output independently of the brain.
