When a person gets injured, their brains release chemicals called opioids into the space between neurons that acts to dull the pain signals. The effect is seen the most in the brain regions called the ventral striatum, amygdala, midline thalamus, and periaqueductal gray.
These substances are the messengers of the inflammation. process, and have been viewed as areas of therapeutic intervention. Collectively they are called autocoids. Autocoids are substances released from the cells in response to various stimuli to elicit normal physiological. responses locally. An imbalance in the synthesis and release of the autocoids contributes significantly to. pathological conditions such as inflammation, allergy, hypersensitivity and ischemia-reperfusion4.
