A noxious stimulus is actually, or potentially, damaging to tissue and liable to cause pain, but does not invariably do so. Some noxious stimuli, particularly in the viscera, do not cause nociceptive responses. Other non-noxious stimuli may cause visceral pain or afferent discharges, comparable ...
The definition of stress, then, is: an event that causes by the body’s natural fight-or-flight response. The “stress response” is what happens when the body reacts to stressors (noxious stimuli). Over time, the mental, behavioral, and physical symptoms of the stress response can wear...
“Rectal hypersensitivity is defined as increased sensitivity to experimental stimuli applied to the gastrointestinal (GI) tract. It can arise due to a combination of either heightened sensitivity to noxious stimuli (hyperalgesia) and/or non-noxious stimuli (allodynia) due to factors such as peripheral...
KEY POINTS 3: Airflow limitation in COPD is progressive, meaning it generally worsens over time. It is associated with an abnormal inflammatory response of the lungs to noxious stimulus, like cigarette smoke, air pollution or harsh chemicals. Risk factor for COPD 1.Genes 2.Exposure to particles...
from Chapter 5 / Lesson 3 41K Pain is a sensation that the body feels when it is damaged or exposed to harmful stimuli. Learn about the mechanisms of pain and nociception, the different types of noxious stimuli, the pain's pathway in the body, and other types of pain. Related...
Differences between Pain in Self and Pain in others: what is Pain Empathy? The available evidence for shared pain representations shows that pain-related activations within the ACC and IC are systematically more posterior when noxious stimuli are applied, imagined, or suggested to Self than to othe...
If you like old veterinary books like I do—and this one’s a classic—you can evensee the book online(the passage is on page 321). There’s actually a well-known phenomenon called adiffuse noxious stimulus, whereby the perception of pain in one area can be diminished by pain in anothe...

For this review, literature on stimulus extraction and processing is considered under the general rubric of “input” factors. As we detail below, accounts of emotion dysregulation often point to anomalies in stimulus processing as important contributory factors. For instance, a person with a ...
This chapter discusses interoceptive sensibility, i.e., the self-reported dimension of interoception. Perceived sensibility to interoceptive cues is determined by the sensibility of internal signals and attentiveness to them; both aspects show considerab
