A sleep spindle may be defined as a section of waxing and waning 8 to 16 Hz oscillation in the EEG.
Research Mednick published earlier this year demonstrated the critical role that sleep spindles play in consolidating information from short-term to long-term memory in the hippocampus, located in the cerebral cortex of the brain.
Wixted determined that a sleep feature known as sleep spindles -- bursts of brain activity that last for a second or less during a specific stage of sleep -- are important for emotional memory.
In motor procedural tasks, an increase in the total number of stage II sleep spindles, especially those in the last quarter of the night, may be seen for the groups that do well on posttraining retesting (Neuron 2002;35:205-11).
While you sleep, your brain stores new information into long-term memory via sleep spindles (these are one- to two-second bursts of brain activity) associated with dreaming.
