p. 645. Why dream? The functions of brain activation in sleeplocked

  • J. Allan Hobson

Abstract

‘Why dream?’ 5 considers the implication for the development of the abundant, florid REM sleep of all mammalian newborns, the changes that occur during brain development, and the effects of upsetting the system by making REM sleep impossible or, at least, very difficult. The fact that human and other mammalian newborns have so much more brain activation in sleep than adults suggests that REM sleep is important for development in some ways that dreaming does not predict. Sleep is essential to life and sleep deprivation can affect basic human functioning. The connection between mammalian thermoregulation and brain activation in REM sleep is also discussed.
