The peduncle is not part of the lateral-spinothalamic-tract-pathway; the medulla receives the info and passes it onto the peduncle from elsewhere (see somatosensory system). The thalamus is where pain is thought to be brought into perception ; it also aids in pain suppression and modulation, acting like a bouncer , allowing certain intensities ...
A circuit diagram of postsynaptic inhibition (A, B) and presynaptic inhibition (C). Excitation is shown in green and inhibition is shown in red. Presynaptic inhibition is a phenomenon in which an inhibitory neuron provides synaptic input to the axon of another neuron (axo-axonal synapse) to make it less likely to fire an action potential.
Descending pathways also activate opioid receptor-containing parts of the spinal cord. [citation needed] Afferent pathways interfere with each other constructively, so that the brain can control the degree of pain that is perceived, based on which pain stimuli are to be ignored to pursue potential gains.
The neural pathways that go to the brain are structured such that information about the location of the physical stimulus is preserved. In this way, neighboring neurons in the somatosensory cortex represent nearby locations on the skin or in the body, creating a map or sensory homunculus .
Descartes' pain pathway: "Particles of heat" (A) activate a spot of skin (B) attached by a fine thread (cc) to a valve in the brain (de) where this activity opens the valve, allowing the animal spirits to flow from a cavity (F) into the muscles causing them to flinch from the stimulus, turn the head and eyes toward the affected body part, and ...
Recent studies have demonstrated that electrical stimulation of nerves leads to inhibitory input to the pain pathways at the spinal cord level. [7] PNS is most effective in the treatment of neuropathic pain (e.g., posttraumatic neuropathy, diabetic neuropathy) when the nerve lesion is distal to the site of stimulation.
Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. [3] Pain is the most common reason for physician consultation in most developed countries.
