Our topic today is the mind-brain relationship, and.
For thousands of years, philosophers have pondered our role in the universe. The study of social structures began as the study of our souls. Only by turning inward could we unravel the mysteries of our institutions. Society was viewed as a reflection and extension of our inner-selves. A few hundred years ago, Descartes introduced the scientific method of inquiry and dramatically changed the way that we searched for answers. The scientific method stressed the individuality and separateness of things.
Institutions could be understood by dissecting and analyzing the individual components. The inquirer was simply a passive observer of external phenomena. This paradigm went unchallenged for over three hundred years. The twentieth century began with Einstein’s theory of relativity. The observer was no longer external to the phenomena being studied. In fact, all patterns could be described only relative to the observer. At first, Einstein’s theory was confined to the physical world, however, twenty years later, von Bertalanffy extended the idea of relativity to the social sciences.
General systems theory could be used to examine both the physical and social sciences. The role of the mind in the construction of reality became an issue of concern. In fact, for some scientists, it had now become a central theme. In the ‘s Wilder Penfield presented convincing evidence that memories were stored in specific locations in the brain. Penfield performed surgery on epileptic patients and found that when he stimulated the temporal lobes, the patients relived experiences from the past.
He found that whenever he stimulated a specific region of the brain, it evoked the same memory. In his book The Mystery of the MindPenfield described the patients experience as a “flashback”, where the patient actually re-lived the experience. Penfield concluded that this meant that all experiences were stored in specific locations of the brain in memory engrams. In an effort to verify Penfield’s experiments, biologist Karl Lashley began searching for the elusive engrams.
He had trained rats in maze-running abilities and then attempted to surgically remove the portion of the rat’s brains that contained the maze-running knowledge. Lashley found that no matter what portion of the brain he removed, the rats retained their maze-running knowledge.
Even when massive portions of the brain were removed, the rats were still able to navigate through the maze.
Karl Pribrama student of Penfield, was astonished by Lashley’s research. Pribram noticed that when brain-injured patients had large sections of their brain removed, they did not suffer a loss of any specific memories. Instead, the patient’s memory became increasingly hazy as greater portions of the brain were removed. Further research indicated that Penfield’s experiments could be only duplicated on epileptic patients. Pribram came to the conclusion that memories are not localized in any specific brain cells, but rather, memory seemed to be distribution throughout the whole brain.
The problem was that there was simply no known mechanism that would explain how this was possible.
Pribram remained puzzled until the mid ‘s, when he ran across an article in Scientific American describing the priram of laser hologram. He immediately synthesized the information and hypothesized that the mind itself was operating in a holographic manner. Anatomist Paul Pietsch simply could not believe Pribram’s theory, and he set out to disprove the holographic theory of the brain. After performing thousands of operations on salamanders, he became convinced that the mind perceives and stores information by encoding and decoding complex interference patterns.
A hologram is created by splitting a laser beam into two separate beams.
One beam is bounced off an object, and the other serves as a reference beam. An interference pattern is created that bears little resemblance to the object, however, it contains all the information necessary to recreate the image of the object. The most remarkable feature to Hollgraphic was the idea that a photographic plate containing a laser image could be broken in two, and each half would contain the complete image of the object, but with less resolution.

This was identical to the way that memory in the brain seemed to be operating. Regardless of how many times the photographic plate was broken, each piece contained the information necessary to reconstruct the entire image. Pribram hypothesized that kadl neurons, axions, and dendrites of the brain create wave-like patterns that cause an interference pattern.
In he published his findings and during the kwrl few years he refined his theory. According to Pribram, a holographic theory explains many of the mysteries of the brain, including the enormous capacity of the brain for the storage and retrieval of information. By the ‘s several other researchers had expanded Pribram’s theory. British physicist Pieter van Heerden proposed that our ability to recognize familiar objects is similar to recognition holography.
A similar technique known as interference holography could explain our ability to perceive differences in a object that has changed. Harvard researchers Daniel Pollen and Michael Tractenberg studied individuals with eidetic photographic memories and proposed the idea that memory is related to an individual’s ability to create holographic images in the brain.
People with outstanding memories are better able to access larger portions of their brains. One distinguishing characteristic of a hologram is the ability to create a pribbram image.
A virtual image is a three-dimensional extension in space that appears to exist, yet contains no substance. We generally believe that we are able to clearly distinguish between external and internal events, however, considerable holograhpic has shown that the division marl not as well-defined as we perceive.
The Holographic Brain – Ascension Now
The “world-out-there” and the “world-in-here” are not always clearly delineated. In the late ‘s Georg von Bekesy demonstrated that blindfolded subjects could be induced to experience sensations in areas outside of marl body. By attaching vibrators to their knees, von Bekesy was able to alter subject’s perceptions of the location of the vibrators so they believed that they were experiencing sensations in the space between their knees.
This artificially created phenomena is similar to the phantom limb pain experienced hoolgraphic amputees. Research in the ‘s had shown that each brain cell in the visual cortex responds to a specific pattern.
Some brain cells fired when horizontal lines were perceived, while others responded to vertical lines.
Berkeley neurophysiologists Russel and Karen DeValois demonstrated kalr the brain was using Fourier mathematics to decode visual images. Recently, Fourier analysis has been used to explain our perception of hearing and smell.
Holonomic brain theory
The brain operates as a complex frequency analyzer. The problem with the holographic model comes when we try to understand what the brain is actually perceiving.
The holographic model implies that our perceptions are merely an illusion. If we are perceiving an interference pattern, what is the true nature of thing we are perceiving? The hologram consists of pgibram a reflected and reference beam. What is the nature of the thing being reflected? Or equally illusive, what is the brain’s equivalent of a reference beam?
Quantum physics has presented us with a puzzling picture of the nature kagl reality. Physicists hologrqphic demonstrated that quanta can manifest themselves as either particles or waves. When scientists are not looking at electrons, they always exist as a wave, and whenever they design an experiment to observe the elections, they always appear as particles. Danish physicist Niels Bohr pointed out that it is meaningless to talk about the properties and characteristics of a particle that is not being observed.
Einstein did not accept Bohr’s argument.
He believed that Bohr had to be wrong because the implications of quantum theory were simply too astounding Talbot,p. At the heart of the controversy was the idea of instantaneous communication between particles. When two complimentary hollographic were allowed to travel apart, their polarizations could be simultaneously measured. Quantum theory predicted that regardless of the distance between the particles, their polarizations would always be the same. The act of measuring one would force the polarization of the other.
Einstein interpreted this to mean that quantum theory braij incorrect because nothing could travel faster than the speed of light. Bohr argued that Einstein was incorrect in thinking of the particles as separate. He maintained that they were part of an indivisible system. Quantum theory proved to be incredible successful and became the accepted theory even though the technology did not exist to actually perform the experiment. Princeton physicist David Bohm became a believer in holographic systems during his study of plasma systems.
He found that when a gas became a plasma, the individual electrons began behaving as a unified whole. The electrons became engaged in a process of self-organization. Bohm became disillusioned with quantum theory because privram attempted to isolate cause-and-effect relationships from the universe as a whole.
He maintained that only a holistic view would explain the electron co-ordination in high energy plasma systems. Furthermore, Bohm argued that space grain was an illusion, and that it was meaningless braun discuss the separateness of things at the quantum level.
Physicists began describing the quantum potential in terms of nonlocal connections. By the ‘s Bohm began to view chaos as a misnomer. He believed that “randomness” contains a hidden order, and that we perceive disorder only because of our limited understanding of the complexity of the processes involved.
InBohm published his first book on the holographic nature of the universe entitled Wholeness and the Implicate Order. In it, he referred to our level of existence as the explicate unfolded order. He maintained that there was a deeper level of order in the universe which he called the implicate order. The constant flow of energy between the explicate holographif implicate pribeam of reality offered an explanation of nonlocal phenomena.
Bohm referred to the universe as a dynamic holomovement. Our Cartesian akrl of the world makes it difficult to comprehend the implications of Bohm’s theory. We have a tendency to divide things into parts and give them unique names. Holographic theory is an extension of general system theory because it recognizes that the boundaries of a system are an artificial construct.
System theory stresses the relationships between the components of the system, however, the boundaries of the system are defined to suit the researcher’s purpose.
