Sensory Hubs Drift around Brain although They Should Not

Abstract

Sensory hubs of the sensory cortex responsible for integrated brain function are found to behave in an unexpected manner. According to the textbook wisdom, sensory hubs responsible for sensory percepts should be static structures. Sensory hubs are however drifting in a time scale of months. The phenomenon is called representational drift. In this article a model for the drift is discussed. The TGD based model for the brain relies on the notion of the magnetic body (MB) carrying phases of ordinary matter with a non-standard value of Planck constant h_eff = nh₀behaving like dark matter. MB with h_eff > h is in the role of master and receives sensory information from BB and controls it. This leads to a radically new view about information processing in the brain. MB would take care of the necessary teaching of the neurons of the shifted sensory hub - in analogy with associative learning. In the teaching MB would use virtual sensory input to the neuronal hub, which is also necessary for the generation of sensory mental images as standard mental images. The standard mental images could be genetically inherited and represented at MB using "dark genes".
