Schrödinger wave holography in brain cortex

An explanation for electroencephalogram (EEG) activity is proposed. Under suitable assumptions concerning the active transport of ${\mathrm{Na}}^{+}$-${\mathrm{K}}^{+}$ ions through the glial tissue in brain cortex, a Schrödinger-like equation for ion displacement waves is easily obtained. Theoretical wave-propagator diagrams are in perfect agreement with experimental stimulus-response patterns directly recorded on brain cortexes. Conditions for effective Schrödinger wave holography and its greater efficiency in comparison with D’Alembert wave holography, are briefly discussed. The need for ‘‘reference-wave’’ recruiting device and for a receptor arrangement, for holographic information recovery in proximity of the signal sources, lead to brain-organization models in good agreement with diagrams reported by neurophysiologists.
