Pain01:20

Pain

1.8K
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...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.5K
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...

Nociception01:44

Nociception

34.3K
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.

Analgesia and Pain Management01:25

Analgesia and Pain Management

2.8K
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...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

855
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Time Course of Drug Effect01:14

Time Course of Drug Effect

2.9K
The progression of a drug's impact can be analyzed by examining both the concentration-time course and the effect-time course. The concentration-time course is determined by the drug's half-life and is influenced by factors such as its pharmacokinetics, including absorption, distribution, metabolism, and elimination. The effect of the drug is often related to its concentration in the plasma and is calculated using the maximum drug effect and the plasma concentration that generates 50...

Area of Science:

  • Neuroscience
  • Chronobiology
  • Pain Research

Background:

  • Chronic pain significantly impacts patients' quality of life.
  • The subjective experience of time can be altered in various neurological and psychological conditions.
  • The relationship between pain perception and temporal processing remains incompletely understood.

Purpose of the Study:

  • To investigate the neural mechanisms underlying the interaction between chronic pain and time perception.
  • To identify specific brain circuits involved in modulating temporal experiences during persistent pain states.

Main Methods:

  • Utilized functional magnetic resonance imaging (fMRI) to monitor brain activity in participants with chronic pain.
  • Employed psychophysical tasks to assess time perception under different pain conditions.
  • Analyzed neural data to correlate brain circuit activation with subjective time alterations.

Main Results:

  • Identified two distinct brain circuits significantly involved in the chronic pain-time interaction.
  • Demonstrated that activation patterns in these circuits correlate with the degree of temporal distortion experienced by patients.
  • Found that specific neural pathways modulate the subjective passage of time during chronic pain.

Conclusions:

  • Two key brain circuits play a crucial role in mediating the influence of chronic pain on time perception.
  • These findings provide novel insights into the neurobiological underpinnings of altered time experience in chronic pain.
  • Targeting these circuits may represent a future therapeutic strategy for managing pain-related temporal disturbances.
