Sj. Fung et al., Hypocretin (orexin) input to trigeminal and hypoglossal motoneurons in thecat: a double-labeling immunohistochemical study, BRAIN RES, 903(1-2), 2001, pp. 257-262
In trigeminal and hypoglossal motor nuclei of adult cats, hypocretin immuno
reactive fiber varicosities were observed in apposition to retrogradely lab
eled motoneuron somata and dendrites. Among those lateral hypothalamus neur
ons that project to the hypoglossal nucleus some were determined to be hypo
cretin immunoreactive and were located amongst the single-labeled hypocreti
nergic neurons. These data suggest that hypocretin may play a role in the s
ynaptic control of these motoneurons. (C) 2001 Elsevier Science B.V. All ri
