Page "Visual memory" Paragraph 34

Findings surrounding sleep and visual memory have been mixed.

Studies have reported performance increases after a bout of sleep compared with the same period of waking.

The implications of this are that there is a slow, offline process during sleep that strengthens and enhances the memory trace.

Further studies have found that quiet rest has shown the same learning benefits as sleep.

Replay has been found to occur during post-training quiet wakefulness as well as sleep.

In a recent study where a visual search task was administered quiet rest or sleep is found to be necessary for increasing the amount of associations between configurations and target locations that can be learned within a day.

Reactivation in sleep was only observed after extensive training of rodents on familiar tasks.

It rapidly dissipates ; it also makes up a small proportion of total recorded activity in sleep.
