摘要：
Study Objectives: To examine the integrity of sleep-promoting neurons of the ventrolateral preoptic nucleus (VLPO) in postmortem brains of narcolepsy type 1 patients. Methods: Postmortem examination of five narcolepsy and eight control brains. Results: VLPO galanin neuron count did not differ between narcolepsy patients (11,151 +/- 3,656) and controls (13,526 +/- 9,544). Conclusions: A normal number of galanin-immunoreactive VLPO neurons in narcolepsy type 1 brains at autopsy suggests that VLPO cell loss is an unlikely explanation for the sleep fragmentation that often accompanies the disease.
