The somatosensory systems also monitor the temperature of the body, external objects and environment, and provide information about painful, itchy and tickling stimuli. The sensory information processed by the somatosensory systems travels along different anatomical pathways depending on the information carried.
The temperature that is called painful 50 percent of the time would be the pain detection or sensory threshold. In contrast to this relatively reproducible pain-detection threshold, tolerance for pain differs widely among individuals.
property (e.g., temperature), together with tracts and nuclei that transmit information about four major general somatic modalities--the sensa- tions of pain (signaling tissue damage or chem- ical irritation), temperature (warmth or cold), touch, (for recognition of size, shape, and tex- ture), and proprioception (sense of static posi- tion and ...
Defending body temperature against environmental thermal challenges is one of the most fundamental homeostatic functions governed by the nervous system. Here we show a novel somatosensory pathway, which essentially constitutes the afferent arm of the thermoregulatory reflex triggered by cutaneous sensation of environmental temperature changes.
23 Ιουλ 2014 · In general, skin temperatures below ∼ 15 °C or above ∼ 45 °C are associated with pain and considered to be noxious 6, 9. Based on their response profiles, temperature-sensitive neurons can ...
Temperature information is sensed by neurons with cell bodies in primary sensory ganglia (or trigeminal ganglia), and then it is transmitted to the dorsal horn of the spinal cord (or chief sensory nucleus of V), the lateral parabrachial nuclei, and finally the preoptic area.
1 Ιαν 2012 · The subjective perception elicited by a brief, intense stimulus is of a sharp, short-duration pain (first pain) followed by a dull, prolonged pain (second pain). First pain is transmitted by the A-delta fibers that convey information from the thermal and mechanical receptors.
