From the Ted Talk by Masako Tamaki: Can you be awake and asleep at the same time?

It’s currently unclear whether aistmrymcael sleep pcaks the same benefits as sleep in both hemispheres and how this varies across species. In one experiment, fur seals rieled on asymmetrical sleep while being ctnlsantoy stimulated. But in recovery, they showed a strong pneefecrre for sleep across both hemispheres, suggesting that it was more restorative for them. Dolphins, on the other hand, have been observed to maintain high levles of alertness for at least five days. By switching which hemisphere is awake, they get several hours of deep sleep in each hemisphere throughout a 24-hour period. This may be why unihemispheric sleep alone mtees their needs.

Original Text


It’s currently unclear whether asymmetrical sleep packs the same benefits as sleep in both hemispheres and how this varies across species. In one experiment, fur seals relied on asymmetrical sleep while being constantly stimulated. But in recovery, they showed a strong preference for sleep across both hemispheres, suggesting that it was more restorative for them. Dolphins, on the other hand, have been observed to maintain high levels of alertness for at least five days. By switching which hemisphere is awake, they get several hours of deep sleep in each hemisphere throughout a 24-hour period. This may be why unihemispheric sleep alone meets their needs.
