Karl H. Pribram (/ˈpraɪbræm/; German: [ˈpʁiːbram]; February 25, 1919 – January 19, 2015) was a neurosurgeon, neuroscientist and theoretical philosopher described by his peers as the “Einstein of Brain Science” and the “Magellan of the Mind” for his groundbreaking research into the “functions of the brain’s limbic system, frontal lobes, temporal lobes, and their roles in decision making and emotion.”

Pribram is internationally known for his pioneering research on the structure and function of the brain, his development of the Holonomic Brain Model of cognitive function (with quantum physicist David Bohm) and his multiple contributions to neurological research focused "the relationship between brain function and mental processes" including memory, perception, emotion, motivation, consciousness and the related structures of the brain.

Teaching Career and Research

In the 1940s, Pribram became one of the first 300 board-certified neurosurgeons in the world after receiving his MD from University of Chicago. Throughout his life, Pribram would engage in pioneering work on the definition of the limbic system, the relationship of the frontal cortex to the limbic system, the sensory-specific association cortex of the parietal and temporal lobes, and the classical motor cortex of the human brain.

Pribram's interest in research led him to work with Karl Lashley at the Yerkes Primate Center, known as the “most important institute for neuropsychological research on animals in the 1940s.” Shortly after the end of WWII, Pribram succeeded Lashley as director of Yerkes and “added neurosurgical sophistication” that allowed the field of animal neuropsychology to expand and flourish during his time as director. These early years would prove to be influential in his development of theories about the structure of the brain and related mental processes. Two of the earliest discoveries Pribram made while at Yerkes were of the relationship between the frontal cortex and the limbic forebrain, and the relationship between the posterior cortex and sensory specific sectors.

In 1948, Pribram was invited to join the Department of Physiology at Yale University, where he would continue his research and teach neurophysiology and physiological psychology for the next decade. While at Yale, Pribram established and directed the Psychophysiology Laboratory at the Institute for Living in Hartford, which “became a mecca for students intensely interested in the relationship between brain and behavior.” As Director of the Psychophysiology Laboratory, Pribram would conduct some of the earliest research on brain circuitry with Mortimer Mishkin.

During this time, Pribram established relationships with psychologists at Harvard University and “learned a great deal from S.S. Stevens, Gary Boring, and Georg von Bekesy.” Additionally, Pribram noted that his interactions with B.F. Skinner at Harvard would influence his research into cognitive neuropsychology.

After his tenure at Yale, Pribram moved to the Center for Advanced Study in the Behavioral Sciences at Stanford University, where he continued to teach neurophysiology and physiological psychology for the next 30 years. During this time, Pribram pioneered the field of neuropsychology (a term that he coined), leading groundbreaking research into the interrelations of the brain, behavior, and the mind.

In 1975, Barbara Honegger, a medical school secretary at Stanford University, alleged that Pribram "struck her in the head" and that she was "denied a job rank she was entitled to." Stanford University put Pribram on two years probation and lowered his salary following a university investigation. Honegger is known for her connection to the 1980 October Surprise theory.

While at Stanford, Pribram received a Lifetime Research Career Award from the National Institutes of Health as Professor Emeritus of Neuroscience in the Departments of Psychology and Psychiatry.

Upon becoming emeritus at Stanford University, Pribram accepted the position of the James P. and Anna King Distinguished Professor at Radford University and, in 1989, was appointed Eminent Scholar of the Commonwealth of Virginia. Radford built the Center for Brain Research and Informational Sciences (B.R.A.I.N.S.) for Pribram to direct with the support of Alastair Harris, chair of the psychology department.

After 60 years of leading research and development in the field of brain research, Pribram was appointed Distinguished Professor of Psychology and Cognitive Neuroscience at Georgetown University in 1998. Simultaneously, he was appointed Distinguished Professor in the Engineering and Computer Science Department at George Mason University.

Holonomic model

Main articles: Holonomic brain theory and Holographic consciousness

Pribram's holonomic model of brain processing is described in his 1991 Brain and Perception, which contains the extension of his work with David Bohm. It states that, in addition to the circuitry accomplished by the large fiber tracts in the brain, processing also occurs in webs of fine fiber branches (for instance, dendrites) that form webs, as well as in the dynamic electrical fields that surround these dendritic "trees". In addition, the processing occurring around these dendritic trees can influence that occurring in those trees of nearby neurons whose dendrites are entangled but not in direct contact (known as ephaptic signaling). In this way, processing in the brain can occur in a non-localized manner. This type of processing is properly described by Dennis Gabor, the inventor of holography, as quanta of information he called a "holon", an energy-based concept of information. These wavelets are used in quantum holography, the basis of MRI, PET scans and other image-processing procedures .

Gabor wavelets are windowed Fourier transforms that convert complex spatial and temporal patterns into component waves whose amplitudes at their intersections become reinforced or diminished . Fourier processes are the basis of holography. Holograms can correlate and store a huge amount of information and have the advantage that the inverse transform returns the results of correlation into the spatial and temporal patterns that guide us in navigating our universe.

David Bohm suggested that were we to view the cosmos without the lenses that outfit our telescopes, the universe would appear to us as a hologram. Pribram extended this insight by noting that were we deprived of the lenses of our eyes and the lens-like processes of our other sensory receptors, we would be immersed in holographic experiences.

Other contributions

In the late 1940s and early 1950s, Pribram's neurobehavioral experiments established the composition of the limbic system and the executive functions of the prefrontal cortex. Pribram also discovered the sensory specific systems of the association cortex, and showed that these systems operate to organize the choices we make among sensory stimuli, not the sensing of the stimuli themselves.

His account of how his discoveries were made is in his book The Form Within which was published in 2013. It includes stories of his encounters with leading scientists and scholars of the day, and amusing stories like how he lost part of a finger when his hand was slammed down by the chimpanzee Washoe at the University of Oklahoma.

In 1999, he was the inaugural winner of the Dagmar and Václav Havel Award for uniting the sciences and the humanities. He died in 2015 in Virginia, aged 95.
