Human analogue of the Morris Water Maze task. A) The real-space navigation setting. B) The scheme of the task showing an aerial view of the arena (large white circle) with starting point (red filled circle), orientation cues (red and green lines), and goal (purple circle). C) The scheme of 4 individual tasks: allocentric-egocentric (i.e., training; designed to use the starting point and 2 orientation cues for navigation), egocentric (designed to use the starting point for navigation), allocentric (designed to use 2 orientation cues for navigation) and allocentric delayed (identical to the allocentric task administered 30 minutes after its completion). D) An aerial view of the arena rotated 180 degrees from the previous trial shown in B.
