Abstract

In trigeminal and hypoglossal motor nuclei of adult cats, hypocretin immunoreactive fiber varicosities were observed in apposition to retrogradely labeled motoneuron somata and dendrites. Among those lateral hypothalamus neurons that project to the hypoglossal nucleus some were determined to be hypocretin immunoreactive and were located amongst the single-labeled hypocretinergic neurons. These data suggest that hypocretin may play a role in the synaptic control of these motoneurons.
