Have you heard of the 'strange loop'? In Quantum Physics, it's called tangled hierarchy.
Douglas Hofstadter was the first person to describe it in his famous book Gödel, Escher, Bach: An Eternal Golden Braid when he was researching on the sense of "I" consciousness. He then went one step further in his next book, I Am a Strange Loop to elaborate more.
Dr. Amit Goswami describes him as one of the brilliant physicists of today's time. Hofstadter was in fact one of Dr. Goswami's students.
This strange loop is a system that moves upwards or downwards only and finds itself back to where it started.
Our brain has this tangled hierarchical system (a system of the consciousness) where this strange loop tends to appear. Our perception and memory is the very system where one cannot function without the other. Perception needs memory at the same time memory needs perception. They basically co-create each other and are depended on each other. Both arrive at the same time and both find themselves back to where they started.
