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.

Was it a Special Brain ?And if so, in what sense ?

Einstein’s Brain
Like all of us,
Einstein’s Brain had:
~ 1011 Neurons
~ 1016 Synaptic connections

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

Seizure (ictal)

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 ?

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

All the information describing the 3-D scene is encodedon 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
![Page 46: Based on a Series of Public Lectures, University of Indiana, Bloomington 1972](https://reader036.vdocuments.us/reader036/viewer/2022081514/56649d575503460f94a35f4e/html5/thumbnails/46.jpg)
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”
