Photons Do Collapse In the Retina Not in the Brain Cortex: Evidence from Visual Illusions
While looking for evidence of quantum coherent states within the brain, many quantum mind advocates proposed experiments based on the assumption that the coherent state of a photon entering the visual system could somehow be preserved through the neural processing, or in other words they suppose that photons collapse not in the retina, but in the brain cortex. In this paper we show that photons do collapse within the retina and subsequent processing of information at the level of neural membranes proceeds. Moreover, we explicitly stress on the fact that due to existent amplification of the signal produced by each photon, a basic quantum mechanical theorem forbids the photon state to be teleported from the retina to the brain cortex. The changes of the membrane potential of the neurons in the primary visual cortex are shown to be relevant to inputting visual sensory information that is already processed and is not identical to the visual image entering in the retina. A striking evidence for the existent processing of the incoming visual information by the retina is provided by visual illusions resulting from the lateral inhibition mechanism.
