Activity in many parts of the brain is associated with pain perception. Some of the known parts for the ascending pathway include the thalamus, hypothalamus, midbrain, lentiform nucleus, somatosensory cortices, insular, prefrontal, anterior and parietal cingulum. [2] Then, there are also the descending pathways for the modulation of pain sensation.
Endorphins (contracted from endogenous morphine) [1] [2] [3] are peptides produced in the brain that block the perception of pain and increase feelings of wellbeing. They are produced and stored in the pituitary gland of the brain.
Area S2 processes light touch, pain, visceral sensation, and tactile attention. S1 processes the remaining info (crude touch, pain, temperature). [13] [14] [15] BA7 integrates visual and proprioceptive info to locate objects in space. [16] [17] The insular cortex (insula) plays a role in the sense of bodily-ownership, bodily self-awareness, and ...
Further, the insula is where a person imagines pain when looking at images of painful events while thinking about their happening to one's own body. [29] Those with irritable bowel syndrome have abnormal processing of visceral pain in the insular cortex related to dysfunctional inhibition of pain within the brain. [30]
The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [1] [2] PAG is also the primary control center for descending pain modulation. It has enkephalin-producing cells that suppress pain.
The basal ganglia are a set of subcortical structures that direct intentional movements. The basal ganglia are located near the thalamus and hypothalamus. They receive input from the cerebral cortex, which sends outputs to the motor centers in the brain stem. A part of the basal ganglia called the striatum controls posture and movement.
The end result is that the brain’s pain inhibiting system is activated, thus reducing pain. But, more importantly, “the peptides themselves, when they’re released, give us a sense of well ...
Thus, the brain controls the perception of pain quite directly, and can be "trained" to turn off forms of pain that are not "useful". This understanding led Melzack to assert that pain is in the brain. [citation needed] Gate control theory influenced the development of mindfulness-based pain management (MBPM). [12]
