“Motor memory”: the brain develops it in sleep

“Motor memory”: the brain develops it in sleep.


A California team has stated that “motor memory” consolidates during sleep. Basically, it reviews the trials and errors by eliminating the actions that the brain deems good. The process of “motor memory” connects three different brain regions and takes place in the non-REM phase. Sleep is essential, because while you sleep you focus on failures. A method to carry forward the elements of success.


The three areas of the brain in question are the hippocampusmotor cortex, and prefrontal cortex. The hippocampus is responsible for memory and navigation. In fact learning, the prefrontal cortex coordinates with the hippocampus. Then in slow learning the prefrontal cortex binds to the motor cortex and hippocampus. This phase leads to the switching off of signals associated with failures and the switching on of those linked to success . When the three regions are synchronized, the hippocampus decreases its role and successful actions become part of the “motor memory”. 

The experimentation of the study took place on animals. When the animals first learned the action, the signals were garbled. But when they learned the actions to be successful, the signals synced up with success rates of 70%. From there the brain seems to ignore the errors and maintains the “motor memory”.
