Paradoxically one of the greatest advantages of mind maps is that they are seldom needed again. The very act of constructing a map is itself so effective in fixing ideas in memory that very often a whole map can recalled without going back to it at all. A mind map is so strongly visual and uses so many of the natural functions of memory that frequently it can be simply read off in the mind's eye.
