Thermosensation

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Nociception

Nociception

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...

Blood and Nerve Supply to the Bones

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Tactile and Chemical Senses

Tactile and Chemical Senses

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...

Pain

Pain

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Dynamic Quantitative Sensory Testing to Characterize Central Pain Processing

Dynamic Quantitative Sensory Testing to Characterize Central Pain Processing

Published on: February 16, 2017

Sensory deprivation and pain thresholds.

J VERNON, T E McGILL

Science (New York, N.Y.)

|February 3, 1961

Summary

Sensory deprivation for four days significantly reduced electrical pain perception. This finding suggests altered pain sensitivity following reduced sensory input.

Area of Science:

Neuroscience
Pain Research
Sensory Perception

Background:

Sensory input is crucial for maintaining normal physiological functions.
Altered sensory environments can impact various bodily systems.
Understanding pain perception mechanisms is vital for pain management.

Purpose of the Study:

To investigate the effect of sensory deprivation on pain thresholds.
To determine if reduced sensory input influences the perception of pain.

Main Methods:

Participants underwent a four-day period of controlled sensory deprivation.
Electrical stimulation was used to induce pain.
Pain thresholds were measured before and after the deprivation period.

Keywords:

OZONE/toxicology

Main Results:

A statistically significant decrease in pain threshold was observed after four days of sensory deprivation.
Participants reported lower intensity of pain at equivalent electrical stimulation levels post-deprivation.

Conclusions:

Four days of sensory deprivation can lead to heightened sensitivity to electrically induced pain.
Reduced sensory input may modulate pain processing pathways in the nervous system.
Further research is warranted to explore the long-term effects and underlying neural mechanisms.
