Holonomic brain theory is a branch of neuroscience investigating the idea that consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [ 1 ]
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. [1] 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 ...
In the 1970s, a number of researchers invoked holography as a structure that could explain the distribution of memory within the brain. [ 10 ] [ 13 ] These theories later gained more credence with the discovery of quantum effects in neuron microtubules by Karl Pribram , suggesting the possibility of highly coherent informational states similar ...
The quantum mind or quantum consciousness is a group of hypotheses proposing that local physical laws and interactions from classical mechanics or connections between neurons alone cannot explain consciousness, [1] positing instead that quantum-mechanical phenomena, such as entanglement and superposition that cause nonlocalized quantum effects, interacting in smaller features of the brain than ...
In the case of consciousness, Bohm pointed toward evidence presented by Karl Pribram that memories may be enfolded within every region of the brain rather than being localized (for example, in particular regions of the brain, cells, or atoms). Bohm went on to say:
Notable theories falling into this category include the holonomic brain theory of Karl Pribram and David Bohm, and the Orch-OR theory formulated by Stuart Hameroff and Roger Penrose. Some of these QM theories offer descriptions of phenomenal consciousness, as well as QM interpretations of access consciousness.
Orch OR has been criticized both by physicists [14] [54] [34] [55] [56] and neuroscientists [57] [58] [59] who consider it to be a poor model of brain physiology. Orch OR has also been criticized for lacking explanatory power ; the philosopher Patricia Churchland wrote, "Pixie dust in the synapses is about as explanatorily powerful as quantum ...
A number of researchers, most notably Karl Pribram and David Bohm, have proposed holographic models of consciousness [13] as a way to explain number of problems of consciousness using the properties of hologram. A number of these theories overlap to some extent with quantum theories of mind.
