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

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.

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.

He has measured brain waves in sleeping fruit flies, identified genes that are active in humans during sleep, and demonstrated that sleep enhances learning and memory.

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.

Those who woke during REM sleep and successfully recalled their dreams were more likely to demonstrate a pattern of EEG oscillations called theta waves in frontal and prefrontal cortex areas — the parts of the brain where our most advanced thinking occurs.

In addition, during sleep the brain - wave patterns of dogs are similar to people's, and they exhibit the same stages of electrical activity that are observed in humans — all of which is consistent with the idea that dogs are dreaming.

Scalp electrodes worn at night by nine villagers during nine nights revealed biological signs of relatively light sleep compared with Westerners, including shorter periods of slow - wave and rapid eye movement sleep.

Also, while in lizards slow - wave and REM - sleep have roughly equal durations during each cycle, REM is much shorter then slow - wave sleep in mammals, and both short and irregular in birds.

Another common feature with mammalian sleep was the coordinated activity of cortex with another area during slow - wave sleep: in dragons this other area is the so - called dorsal ventricular ridge.

Theta waves, with high amplitudes and frequencies falling between those of delta and alpha waves, normally appear in adults during light sleep and meditation.

During slow - wave sleep, groups of neurons firing at the same time generate brain waves with triple rhythms: slow oscillations, spindles, and ripples.
