What is the name of the Specialised cells involved in the gate control theory of pain modification?
the hypothesis that the subjective experience of pain is modulated by large nerve fibers in the spinal cord that act as gates, such that pain is not the product of a simple transmission of stimulation from the skin or some internal organ to the brain.
According to one theory, a gate control system in the spinal cord modulates sensory input from the skin to determine whether the input is perceived as painful. This theoretical formulation also may account for moment-to-moment fluctuations in the intensity of perceived pain despite the absence of any stimulus change.
Factors that open the gate There are three main ways in which the gates to pain can be made more open, so that the pain feels worse. These are to do with how we feel about things, how we think about things, and what we are doing.
Due to the observations that raised questions, a new theory of pain was developed in the early 1960s to account for the clinically recognized importance of the mind and brain in pain perception. It is called the gate control theory of pain, and it was initially developed by Ronald Melzack and Patrick Wall.
As our understanding of spinal cord transmission developed over the years, the gate control theory has been updated, but the theory remains important as it allowed understanding that nociceptive signals were processed within the central nervous system before reaching the cortex, resulting in a variable relationship …
Just as you saw with the hand shaking exercise, simple movement can close the pain gate. Other physical movement or stimulation such as massage or acupuncture can help many people as these also create activity in the large nerve fibers.
You can open a gate from your phone via telephone entry systems, IP intercoms, or gate access control systems. In all three methods, you’ll have to install a cell phone gate opener at the gated entrance. Users may also have to download a mobile app onto their cell phones.
The gate through which the pain pathways send signals to the nervous system is located in the dorsal horns of the spinal cord. The dorsal horns are composed of several layers, called laminae. Two of these layers make up the substantia gelatinosa, the hypothesized location of the gate mechanism.
These findings were the basis for the iconic gate mechanism diagram published in the 1965 paper (Figure 3). Both large and small sensory fibers were assumed to project to cells (called T-cells) which projected to the forebrain.
Introduction. The gate control theory of pain developed by Melzack and Wall in 1965  proposes that tiny neural networks distributed along the dorsal horn of the spinal cord are responsible for relieving the pain in a specific body location when an intense tactile stimulation is applied at the same place.
The gate control theory forms the basis of TENS. In this technique, the selective stimulation of the large diameter nerve fibers carrying non-pain sensory stimuli from a specific region nullifies or reduces the effect of pain signals from the region.
The neuromatrix theory of pain proposes that pain is a multidimensional experience produced by characteristic “neurosignature” patterns of nerve impulses generated by a widely distributed neural network-the “body-self neuromatrix”-in the brain.
Endogenous opioids are key mediators in the descending pain suppression pathways. Additionally, monoaminergic neurotransmitters such as norepinephrine, serotonin and dopamine positively or negatively modulate pain signaling, depending on receptor type and location.
Pain is an uncomfortable feeling that tells you something may be wrong. It can be steady, throbbing, stabbing, aching, pinching, or described in many other ways. Sometimes, it’s just a nuisance, like a mild headache.
Pain is a complex physiological process. A pain message is transmitted to the brain by specialized nerve cells known as nociceptors, or pain receptors (pictured in the circle to the right). When pain receptors are stimulated by temperature, pressure or chemicals, they release neurotransmitters within the cells.
Referred pain, as defined by Anderson, is “pain felt at a site different from the injured or diseased organ or body part.”1 Radiating pain, however, is not defined by Anderson; radiating pain is more commonly used in connection with pain perceived in somatic nerve and spinal nerve root distributions (i.e. the …
The four most influential theories of pain perception include the Specificity (or Labeled Line), Intensity, Pattern, and Gate Control Theories of Pain (Fig. 1). The Specificity Theory refers to the presence of dedicated pathways for each somatosensory modality.
A new study published online September in Current Biology suggests that touching an injured area on one’s own body reduces pain by enhancing the brain’s map of the body in a way that touch from another cannot mimic.
The perception of, expression of, and reaction to pain are influenced by genetic, developmental, familial, psychological, social and cultural variables. Psychological factors, such as the situational and emotional factors that exist when we experience pain, can profoundly alter the strength of these perceptions.
The first Ring product not designed for DIY installation, it allows homeowners to remotely operate an electric gate when paired with a Ring Video Doorbell or Ring Camera. … Once you open the live view in the Ring app to see who’s there, you can push a button in the app to open the gate.
COMPATIBILITY: ismartgate works with all gate openers except with Chamberlain, Liftmaster openers with built-in MyQ technology. … Ask Siri, Google Assistant or Alexa to open or close the gate for you.
The access codes work by restricting entry and prompting you to enter a code before entering the gated community. When you enter the correct code, the gate opens and you are allowed to enter. This article explores the security and management of gate codes in gated communities.
The spinal cord carries the pain message from its receptors all the way up to the brain, where it is received by the thalamus and sent to the cerebral cortex, the part of the brain that processes the message.
The cell bodies of primary-order neurons or pain-transmitting neurons reside in the dorsal root ganglia just lateral to the spine along the sensory pathways that penetrate the posterior part of the cord.
Peripheral nerve pathways can be afferent (ascending) pathways that carry sensory impulses toward the CNS.
When we feel pain, such as when we touch a hot stove, sensory receptors in our skin send a message via nerve fibres (A-delta fibres and C fibres) to the spinal cord and brainstem and then onto the brain where the sensation of pain is registered, the information is processed and the pain is perceived.
Aδ fibers carry cold, pressure, and acute pain signals; because they are thin (2–5 μm in diameter) and myelinated, they send impulses faster than unmyelinated C fibers, but more slowly than other, more thickly myelinated group A nerve fibers.
The dorsal horn of the spinal cord is one of the grey longitudinal columns found within the spinal cord. It primarily acts as the termination of primary afferent fibers via the dorsal roots of the spinal nerves.
The pain is real. The phantom part refers to the location of the pain: the missing limb or part of the limb (such as fingers or toes). Phantom limb pain ranges from mild to severe and can last for seconds, hours, days or longer. It may occur after a medical amputation (removing part of a limb with surgery).
The Biopsychosocial Model is the only theory of pain that provides the most comprehensive explanation as to why people have pain as well as the unique nature of each patient’s experience.

When pain persists, there is (i) an increase and diversification of threatening inputs such that the pain neuromatrix can be activated by all manner of threatening stimuli, nociceptive (including immune and endocrine-driven mechanisms) and cognitive–evaluative, and (ii) alterations in the morphology and behaviour of …
The body-self neuromatrix comprises a widely distributed neural network that includes parallel somatosensory, limbic and thalamocortical components that subserve the sensory-discriminative. affective-motivational and evaluative-cognitive dimensions of pain experience.
Chronic pain is pain that is ongoing and usually lasts longer than six months. This type of pain can continue even after the injury or illness that caused it has healed or gone away. Pain signals remain active in the nervous system for weeks, months or years.
The brain stem is a bundle of nerve tissue at the base of the brain. It connects the cerebrum and cerebellum to the spinal cord.
Endorphins: These neurotransmitters than inhibit the transmission of pain signals and promote feelings of euphoria. These chemical messengers are produced naturally by the body in response to pain, but they can also be triggered by other activities such as aerobic exercise.
The researchers traced the pain signalling pathway between the brain and spinal cord in an animal model and found that removing dopamine-containing cells reduced chronic pain.
