The reticular formation may be best known for its role in promoting arousal and consciousness. Robin Lefler noted this while studying the effects of the game with Wesley Crusher in 2368. The nerve fibers in these pathways act in the spinal cord to block the transmission of some pain signals to the brain, activating the endogenous opioid system. Its dorsal tegmental nuclei are in the midbrain while its central tegmental nuclei are in the pons and its central and inferior nuclei are found in the medulla.
