On June 8, a study published in Cell Reports, a journal of Cell Press, showed that when people are resting while awake, the brain's neural replay may help to consolidate their memory of actions
The corresponding author of the study, Leonardo G.
When people learn a new skill, they can intersperse with practice during breaks, and their memory will be consolidated
But what is unclear is how the brain combines discrete motor representations into unified, time-accurate skills during waking periods
To test this idea, the researchers used a brain imaging technique called magnetoencephalography (MEG)
The neural replay lasted only 50 milliseconds-20 times faster than actual behavior
Neural playback involves brain networks such as the hippocampus, sensorimotor and entorhinal areas
Next, the researchers plan to use non-invasive brain stimulation to test whether waking playback plays a causal role in early skill learning, and to determine whether rapid consolidation supports other types of memory
