Chronic but not acute morphine exposure reversibly impairs spike generation and repetitive firing in a functionally distinct subpopulation of orexin neurons

Elizabeth A. Berry, Ellen N. Huhulea, Masaru Ishibashi…·Christopher S. Leonard

This study shows chronic morphine exposure impairs spike generation in a specific subpopulation of orexin neurons, while sparing others, and this effect is reversible.

Opiate anticipation,opiate induced anatomical changes in hypocretin (Hcrt, orexin) neurons and opiate induced microglial activation are blocked by the dual Hcrt receptor antagonist suvorexant, while opiate analgesia is maintained

Ronald McGregor, Ming‐Fung Wu, Thomas C. Thannickal, Jerome M. Siegel

This study shows that suvorexant blocks morphine-induced changes in Hcrt neurons, microglial activation, and anticipatory behavior but preserves morphine analgesia.
