I heard about this theory. In general also our body is made of atoms, electrons, ions and subatomar elements. As consequence the laws of physics have to be applied. The brain is a huge neural network and therefore it can be assumed that also the electrons or energy in the brain make quantum leaps (jumps). If you want so such jumps are not within our body or measurable spectrum, like in an other dimension. Very theoretical physics.
The term for such science regarding the brain is called "neuroquantology". Already 1924 Alfred Lotka examined Quantum Leap in mind brain relations. In 1928 Arthur Eddington examined Quantum mechanics-determinism in the brain. So its nothing new.
Today there is a lot of more science and literature. Just search for neuroquantology and you will find a lot.
