Why Holograms? In the everyday world, a hologram is a special kind of photograph that generates a full three-dimensional image when it is illuminated in the right manner. All the information describing the 3-D scene is encoded on a two-dimensional piece of film, ready to be regenerated If you cut a hologram in half you will have 2 smaller whole images in each half. The "whole in every part" nature of a hologram provides us with an entirely new way of understanding organization and order.

Why Holograms II. Extraction of Relevant Information from Data Assignment of Meaning to Information – Contextual Interpretation Prepare for the Future by Learning from Experience Higher Flexibility for Better Adaptability Identification of Causal Correlations – making sense of Repetitions and Variations Turing, the secrets of Intelligence and Meaning-Based Natural Intelligence

Einstein His Universe His Preserved Brain Was it a Special Brain ? And if so, in what sense ? Einstein Who thought in Holograms
6
Einstein’s Brain Like all of us, Einstein’s Brain had: ~ 10 11 Neurons ~ 10 16 Synaptic connections
8
Not only Einstein, but we all generate 4-Dimensional Causal Holograms How? and How can we prove it?

Epilepsy – the source of recorded human brain activity Some facts: ~ 1% of the population ~ 30% need operation (usually children) ~ 40% of operations fail ~ ?% of operations cause severe damage Recording of Brain Activity for several weeks before dissection Subdural Grids

The Challenge - Onset Normal (inter ictal) Seizure (ictal)
12
Questions: Looking for “function-follow-form” in action What causes brain cells to go into seizures? Could epileptogenic areas be identified when brain is calm? Can functionally distinct areas of cortex be identified? Can information flow be tracked in the cortex? Can we simplify the complexity ?

II. Construction of similarity networks The colors of the lines indicate the similarity The Current Approach mV Time 1 2 3 For example C(1,2) >> C(1,3) Computation of the inter-electrode coherences – C(i,j) The similarity of the activity I. 12 3

Ask anybody what the physical world is made of, and you are likely to be told "matter and energy." Information in the Holographic Universe Theoretical results about black holes suggest that the universe could be like a gigantic hologram By Jacob D. Bekenstein Scientific AmericanScientific American August 2003 A current trend, to regard the physical world as made of information, with energy and matter as incidentals.

In the everyday world, a hologram is a special kind of photograph that generates a full three-dimensional image when it is illuminated in the right manner. All the information describing the 3-D scene is encoded on a two-dimensional piece of film, ready to be regenerated. Holography may be a guide to a better theory. What is the fundamental theory like? The chain of reasoning involving holography suggests that such a final theory must be concerned with information exchange among physical processes. If so, the vision of information as the stuff the world is made of will have found a worthy embodiment. Boltzmann -> Hasenohrl -> Herzfeld -> Wheeler -> Bekenstein
46
Yet if we have learned anything from engineering, biology and physics, information is just as crucial an ingredient. A ribosome in a cell in can synthesize no proteins without the information brought to it from the DNA in the cell's nucleus. Likewise, a century of developments in physics has taught us that information is a crucial player in physical systems and processes. Indeed, a current trend, initiated by John A. Wheeler is, to regard the physical world as made of information, with energy and matter as incidentals. Ask anybody what the physical world is made of, and you are likely to be told "matter and energy."

As Francis Bacon said: “It would be an unsound fancy and self-contradictory to expect, that things which have never yet been done can be done except by means which never have yet been tried”
