Microinjection of Orexin-A into the Locus Coeruleus Area Induces Morphine Withdrawal Behaviors in Morphine Independent Rats

Research on Addiction, 2012
Introduction: Orexin neuropeptide has a role in opioid withdrawal behaviors. Orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the Locus Coeruleus (LC).

Orexin-A acts on the paraventricular nucleus of the midline thalamus to inhibit locomotor activity in rats

, 2009
Orexins (hypocretins) are novel peptides that have been shown to play a role in control of behavioral arousal. The paraventricular nucleus of the midline thalamus (PVT) is one area of the brain that is the most densely innervated by orexin fibers.
