Pattern theory : Goldscheider [1894] • Proposes that pain is generated by non specified receptor. According to his theory, pain stimulation is carried by small, slow fibers that enter the dorsal horn of the spinal cord; then other cells transmit the impulses from the spinal cord up to the brain.

Instead, different sensations, such as cold, pain, heat, and touch, are detected by the same nerves, which then send specific signal patterns to the brain. Different qualities are attributed to painful sensations, such as burning, pricking, pressing and others (Melzack and Torgerson, 1971; Melzack, 1975). The multiple determinants of pain The neuromatrix theory of pain proposes that the neurosignature for pain experience is determined by the synaptic architecture of the neuromatrix, which is produced by genetic and sensory influences.

In visual neuroscience, where knowledge of brain mechanisms are perhaps a century ahead of that in pain research, there is little doubt that at least in the primary visual cortex the outside world is coded by neurons with receptive fields comprised of lines and/or edges, that is in complete compliance with the pattern theory. ��w3T�PI�2T0 BCcC=S3��\. endstream �F�W�޺�\H�l��Ƅ��F��#�I� 54��rA�'8vB�������%w Pattern theory is variational in that it describes the variability of the phenomena observed in different applications in terms of probability measures that are used with a Bayesian interpretation.

The Specificity Theory of Pain In the 16th century, the French philosopher and mathematician Rene Descartes proposed one of the original theories of pain.

Goldschneider (1920) proposed that there is no separate system for perceiving pain, and the receptors for pain are shared with other senses, such as of touch. Pattern theory, formulated by Ulf Grenander, is a mathematical formalism to describe knowledge of the world as patterns.It differs from other approaches to artificial intelligence in that it does not begin by prescribing algorithms and machinery to recognize and classify patterns; rather, it prescribes a vocabulary to articulate and recast the pattern concepts in precise language. �F�W�޺�\H�l��Ƅ��F��#�I� 54��rA�'8vB�������%w x�s Conceptually, research into phantom limb pain is informed by the particular theory of chronic pain that is dominant at the time the research is undertaken. endobj �F�W�޺�\H�l��Ƅ��F��#�I� 54��rA�'8vB�������%w ��� �0F�=O� ��w3T�PI�2T0 BCcC=S3��\. 2011 Mar;153(3):605; author reply 607.

The Specificity theory and Pattern theory are not sufficient in explaining the experience of pain as the theorists fail to include any psychological aspects of pain. Increasing activity of the transmission cells results in increased perceived pain. The pattern theory, by contrast, proposed that afferent fibers respond to a host of stimulus modalities, and that the ultimate perception depends on the brain's deciphering and interpretation of the patterns of activity across the different nerve fibers.

This model of the neuromatrix stands in contrast to a long held explanatory model of pain that associates the production of pain with tissue damage and its resultant detection by the peripheral nervous system. The most widely accepted and current definition of pain, established by the International Association for the Study of Pain (IASP), is "An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. These transformations express the invariances of the worlds we are looking at. According to this theory, there are no specific nerve fibers or endings used just for the sensation of pain. ͐,.�. Neuromatrix theory of pain The pain neuromatrix theory is a development of the gate control theory of pain. A painful, nociceptive stimulus stimulates primary afferent fibers and travels to the brain via transmission cells. This theory proclaims that pain is signalled via non‐specific channels concerned with conduction of both nociceptive and non‐nociceptive events.
