Holonomic Brain Theory - Lens-defined Model of Brain Function

Lens-defined Model of Brain Function

In this model, each sense functions as a lens, refocusing wave patterns either by perceiving a specific pattern or context as swirls, or by discerning discrete grains or quantum units. David Bohm has said that if you take the lenses away, what you are left with is a hologram.

According to Pribram and Bohm, "future orientation" is the essence of cognitive function, which they have attempted to define through use of the Fourier theorem and quantum mechanical formulae. According to Pribram, the tuning of wave frequency in cells of the primary visual cortex plays a role in visual imaging, while such tuning in the auditory system has been well established for decades. Pribram and colleagues also assert that similar tuning occurs in the somatosensory cortex.

Pribram distinguishes between propagative nerve impulses on the one hand, and slow potentials (hyperpolarizations, steep polarizations) that are essentially static. At this temporal interface, he indicates, the wave interferences form holographic patterns.

Pribram has written, "What the data suggest is that there exists in the cortex, a multidimensional holographic-like process serving as an attractor or set point toward which muscular contractions operate to achieve a specified environmental result. The specification has to be based on prior experience (of the species or the individual) and stored in holographic-like form. Activation of the store involves patterns of muscular contractions (guided by basal ganglia, cerebellar, brain stem and spinal cord) whose sequential operations need only to satisfy the 'target' encoded in the image of achievement much as the patterns of sequential operations of heating and cooling must meet the setpoint of the thermostat."

Famous quotes containing the words model, brain and/or function:

    “The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
    —Erik H. Erikson (20th century)

    “I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose.”
    —Sir Arthur Conan Doyle (1859–1930)

    “The function of comedy is to dispel ... unconsciousness by turning the searchlight of the keenest moral and intellectual analysis right on to it.”
    —George Bernard Shaw (1856–1950)
