How Can the Visual Quantum Information be Transferred to The Brain Intact, Collapsing There and Causing Consciousness?

The main problem which this paper tries to address is whether collapse of the wave function describing the state of a quantum mechanical system occurs, or, rather can occur in the brain of the observer or not. One of the first (relatively) detailed “collapse models” following the original abstract suggestion by von Neumann that collapse occurs in the brain of the observer and is related to consciousness, is the Orch OR model of Penrose and Hameroff. This model was first criticized by Tegmark on the ground that due to decoherence, quantum processing cannot occur in the human brain. This criticism was countered by saying that due to structural shielding, microtubules inside the neurons can be protected against the wet and warm environment inside the brain. Thaheld, however, in a number of papers argued that quantum visual information carried by the photons from the environment cannot reach the brain intact. In other words, the quantum states of the photons would collapse inside the human eye and only classical information would finally reach the brain and hence no collapse and quantum processing in the brain can take place. In this paper we advance a hypothesis that there is the possibility for the quantum states of photons to be transmitted to the brain in a quantum-like manner. Our approach is based on the quantum teleportation mechanism which includes both classical and quantum aspects of information transfer, but the process itself is wholly quantum mechanical.
