The paper develops a new theory of chronic pain and pain relief by extracorporeal shock wave treatment. Chronic pain without underlying anatomical disorder is looked at as a pathological control function of memory. Conditioned reXexes are considered to be engraved memory traces linking sensory input of aVerent signals with motor response of eVerent signals. This feature can be described by associative memory functions of the nervous system. Some conditioned reXexes may cause inappropriate or pathological reactions. Consequently, a circulus vitiosus of pain sensation and muscle and/or vessel contraction is generated when pain becomes chronic (pain spiral). The key feature is a dedicated engram responsible for a pathological (painful) reaction. The pain memory may be explained by the concept of a holographic memory model published by several authors. According to this model it is shown how nervous systems may generate and recall memory contents. The paper shows how extracorporeal shock wave treatment may reorganize pathologic memory traces, thus giving cause to real and permanent pain relief. In a generalized manner, the idea of associative memory functions may help in the understanding of conditioning as a learning process and explain extracorporeal shock wave application as an eYcient treatment concept for chronic pain. This concept may open the door for new treatment approaches to chronic pain and several other disorders of the nervous system.

“…2. Точность аппроксимации импульсного отклика (или ГМ АКФ) -этот вопрос в рамках нашего подхода сводится к аппроксимации показателя степени d(D) посредством (9) и актуален для более сложных схем, в которых импульсный или корреляционный отклик используется для дальнейшей обработки, например, схем резонансной архитектуры, в том числе реализующих модели памяти [15,20,21] и немонотонной логики [22].…”

Предложен подход к аппроксимации передаточной характеристики и отклика в +1-м порядке дифракции 4f-схемы голографии Фурье гауссовоподобной моделью применительно к обработке изображений со степенными пространственно-частотными спектрами мощности. Методом численного моделирования найдены связи параметров моделей аппроксимации и спектров эталонного изображения в зависимости от показателя степени эталонного спектра. Показаны погрешности аппроксимации и возможность их оптимизации в требуемом диапазоне пространственных частот, определяемом нелинейностью экспозиционных характеристик голографических регистрирующих сред. Правомочность подхода подтверждена сравнением результатов численного моделирования с экспериментальными данными. Ключевые слова: голография, преобразование Фурье, пространственно-частотный спектр, импульсный отклик, регистрирующие среды, экспозиционная характеристика.

The accuracy of the impulse response approximation (or GM ACF)this issue within our approach is reduced to the approximation of the exponent d(D) by ( 9) and is relevant for more complex circuits, in which the impulse or correlation response is used for further processing, for example, resonant architecture circuits, including those implementing memory models [15,20,21] and nonmonotonic logic [22].…”

“…But for a number of real recognition conditions, for example, in the presence of projective distortions of the recognizable image relative to the reference one, a simple and convenient model [8] turned out to be insufficienta complete description of both spectra and holograms was required [13], which requires significant computational resources. The complication of problems solved by the Fourier holography method [14][15][16][17][18][19][20][21][22], including computer [16][17][18][19], and the corresponding complication of algorithms also actualizes the issue of adequate, visual and, which is important for practical real-time applications [16][17][18][19] of computationally inexpensive approximation.…”

An approach for approximating the transfer characteristic and response in the +1th order of diffraction of a 4f Fourier holography scheme by a Gaussian-like model as applied to image processing with power-law spatial-frequency power spectra is proposed. The relations between the parameters of the approximation models and the reference image spectra are found by numerical simulation depending on the reference spectrum exponent. The approximation errors and the possibility of their optimization in the required range of spatial frequencies, determined by the nonlinearity of the exposure characteristics of holographic recording media, are shown. The validity of the approach is confirmed by comparing the results of numerical simulation with experimental data. Keywords: holography, Fourier transform, spatial frequency spectrum, impulse response, recording media, exposure characteristic.
