We examined fundus photographs of 5,789 patients (11,578 eyes) and found 39 patches of myelinated nerve fibers in 35 eyes of 33 patients. The prevalence was 0.57%. The lesion was more frequent in females than in males. The patch occurred more often at the superior sectors of the nerve head and in the inferotemporal retina than in other areas.

In undrugged, head-restrained rats, neuronal activity was recorded in and around the laterodorsal hypothalamic area where orexin neurones are distributed. Among 22 neurones observed across whole sleep-waking states, half (n = 11) were most active during paradoxical sleep and least active during waking. Others were equally more active during paradoxical(More)
