Titulo: Adaptive Sleep Loss in Birds
Resumen
Sleep is a prominent part of an animal's daily life. Most theories for the function of sleep
suggest that it plays a role in maintaining adaptive waking performance, although exactly
how remains debated. Sleep might restore brain resources depleted during wakefulness,
repair damage resulting from wakefulness, remove toxins that accumulate during
wakefulness, and strengthen of weaken synapses formed during wakefulness.
Regardless of which theory is correct, all are based on the observation that waking
performance on a variety of cognitive tasks declines as sleep loss accumulates. Despite
this overwhelming evidence, several birds engage in periods of elevated activity that
seemingly leave little time for sleep. In this seminar, I will summarize recent work showing
that birds have an unprecedented ability to maintain adaptive performance despite
forgoing large amounts of sleep. Determining how birds are able to circumvent the drive to
sleep may provide insight into the functions of sleep and the impact that its loss has on
waking performance.
