Pages: 31, Unpublished, PDF - Acrobat A Cortical EMS (Electromagnetic Multipole Solution) model proposes an explanation for why the cortex has features such as an apparent dipole structure, cortical folds, hemispheres, and the reverse lateralization of processing, which occurs in these hemispheres. The mammalian brain is proposed in terms of a dipole structure for the cortex (Cortical EMS) and a linear quadrupole for the limbic system (Limbic EMS). Cortical grey matter is reviewed and it is determined that to have chemical distributions consistent with the structure of a dipole system. It is hypothesised that magnetic interactions through radial glial connexins at the cortex surface form stripe domains which explain its sulci and gryi. The limbic system is similarly explored and proposed to possess that it posseses the structure of a harmonically oscillating linear quadrupole. The emphasis of this project is then on attempting to understand the composite brain structure and their interactions rather than any of its single parts in isolation. From a systems view Limbic EMS tends towards collapse, entwined inside a radiating cortex dipole which tends towards expansion. To elaborate on this interaction further, a ‘collapse-expansion’ paradox and the recurrent cycle between these two systems is contended to a possible developmental model for the evolution of mammalian consciousness. We propose a CorticoLimbic EMS model will aid with understanding the brain’s overall structure. Cortical evolution is proposed as primarily selecting the optimization of gap junction mechanisms to increasingly facilitate brain wide electromagnetic coherence in neurodevelopment as the larger machinery to provide the structure by which its subcomponents can overcome environmental challenges.
