New findings could help with future navigational problems associated with Alzheimer's and other neurological disorders.
Researchers at NYU Langone Medical Center have found that navigational brain cells that help sense direction are as electrically active during deep sleep as they are during wake time—and have visual and vestibular cues to guide them. Such information could be useful in treating navigational problems, among the first major symptoms of Alzheimer's disease and other neurological disorders.
