Columbian ground squirrels retained spatial memories through nine months of hibernation, according to a field study in Alberta. When tested again, experienced squirrels performed 41–98% better than squirrels encountering the maze for the first time.
In male mice, light exposure during the animals’ rest phase impaired long-term object recognition memory after six days. The exposure also disrupted clock-related activity in the brain, while enforced wakefulness without light did not produce the same effects.
Two randomized phase 3 trials found that the oral drug oveporexton improved wakefulness, daytime sleepiness and cataplexy in people with narcolepsy type 1. Increased urinary frequency and temporary insomnia were common among participants who received the drug.
