Brainwaves in wild animals
b) Three toed sloths, for example, sleep far less than once thought.
d) Now, John Lesku of La Trobe University in Melbourne and his colleagues are using neurologgers to investigate whether light pollution interferes with the circadian rhythms of tammar wallabies in Australia.
a) A technology for recording brainwaves in wild animals could awaken a more sophisticated understanding of the function of sleep. Studies using miniature sleep-recording devices known as neurologgers have already challenged several long-held beliefs about the sleeping habits of sloths and birds.
c) And male sandpipers can go almost entirely without sleep during the three-week breeding season, helping maximize success at that time.
