| Outline of Final Research Achievements |
To understand the neural pathways underlying the respiratory variation dependent on sleep/wake states, we examined the orexinergic projection to the parabrachial nucleus. The results of the present study are as follows: (1) in adult, orexin may exert modulatory influence through orexin receptor 2 upon Kolliker-Fuse neurons which send their axons to the rostral ventral respiratory group and phrenic nucleus for eliciting the repiratory facilitation and to the hypoglossal nucleus for eliciting the maintaining the airway patency during wakeful state; (2) in infant, overlapping distribution of orexin-immunoreactive fibers and rostral ventral respiratory group projecting neurons is found in the Kolliker-Fuse nucleus, and orexin B injection into the lateral parabrachial nucleus of the brainstem-spinal cord preparation results in facilitation of respiration.
