For a paper published in the International Journal of Psychophysiology, the researchers observed the EEG measures of 13 autistic children and 13 neurotypical children (children with a mean age of 10 years old without an intellectual deficiency or sleep problem and who were not on medication) and found that disruptions in protective brain waves during sleep are associated with lower results on verbal IQ tests.

Slow oscillations in brain activity, which occur during so - called slow - wave sleep, are critical for retaining memories.

However, despite these similarities, the researchers noted that the relationship between these sleep waves and cognitive performance differs between neurotypical and autistic children, as different brain regions are involved for each group.

The study, which used EEG caps to monitor the brain waves of sleepers in the brain's posterior «hot zone,» pinpointed a new signal that can accurately predict dreaming during non — rapid eye movement sleep.

As we sleep, says Tononi, the brain isn't building but rather downscaling, and these silences between waves play a key role.

Slumber is known to improve recall in creatures from fruit flies to humans, and the reigning theory among neuroscientists has been that the waves of brain activity during deep sleep reactivate neurons that were triggered during the day, strengthening neuronal connections and cementing them into solid memories.

In keeping with earlier studies, the older adults performed less well than the younger ones on the memory test, and showed significant reductions in the slow brain waves associated with deep sleep.

Memory waves It is well established that sleep strengthens newly formed memories, and slow brain waves are thought to enhance the transfer of information from the hippocampus, a brain structure that is crucial to memory formation, to other parts of the brain for long - term storage.

In deep, slow - wave sleep, recordings of the brain's electrical activity show sparse bursts of big, slow waves.

So - called unihemispheric sleep happens in animals when one side of the brain shows waking activity while the other side is asleep (an electroencephalographic recording of brain activity under these circumstances shows slow synchronous waves).

During slow - wave sleep, the hippocampus — a region of the brain that stores recent, episodic memories about discrete events — replays its files for the neocortex, home to more permanent memories.
