response to pain

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

behavioral response to pain

Any process that results in a change in the behavior of an organism as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli.

sensory perception of pain

The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process.

modulation of sensory perception of pain in another organism

A process that modulates the frequency, rate or extent of the sensory perception of pain, the series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal, in a different organism.

detection of mechanical stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a mechanical stimulus is received and converted into a molecular signal.

behavioral response to chemical pain

Any process that results in a change in the behaviour of an organism as a result of a chemical pain stimulus.

regulation of sensory perception of pain

Any process that modulates the frequency, rate or extent of the sensory perception of pain, the series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal.

detection of electrical stimulus involved in sensory perception of pain

The series of events that contribute to the perception of pain in which an electrical stimulus is received and converted into a molecular signal.

detection of temperature stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a temperature stimulus is received and converted into a molecular signal.

detection of chemical stimulus involved in sensory perception of pain

The series of events involved in the perception of pain in which a chemical stimulus is received and converted into a molecular signal.
