Descending inhibitory pathways
WebThe four main descending pathways - from the cortex, the diencephalon, the mesencephalon and the pontobulbar structures - are briefly examined with regard to their … Webmedulla (RVM) are two important areas of the brain involved in descending inhibitory modulation. Both these centres contain high concentrations of opioid receptors and endogenous opioids, which helps explain why opioids are analgesic. Descending pathways project to the dorsal horn and inhibit pain pain transmission.

In this article, we review evidence for facilitatory 5-HT pathways that link spinal cord and brainstem areas involved in mood and emotions.
WebProcessing slow pain signals in the reticular formation and the periaqueductal gray within the brainstem can activate descending pain pathways that do not reach the cerebral cortex. Through inhibitory mechanisms, these can substantially modify the perception of pain by introducing levels of analgesia into the system. Other nerve fibers pass ...

WebBecause the Ib inhibitory interneurons receive convergent multisensory inputs and descending pathways, they may allow fine control of muscle forces, and may be better at protective functions. Also, because the Ib fibers connect widely with the motoneurons innervating muscles working on different joints, the Golgi tendon reflex forms part of ...
