Neuropsychologists confirmed— tomorrow is another day

Scientists from the University of Montreal found that regions of the brain under the cortex play an important role in training the movements of our body and interact more effectively after a night's sleep.

Neuropsychologist Karen Debas said, "Subcortical departments are important in information consolidation, in connection with motor memory. If the consolidation level is measured after a period of sleep, we see that the relationship between the different regions of this network is better optimized". The researchers taught a group of subjects a new sequence of finger movements when playing the piano. The brains were observed using functional magnetic resonance imaging during their performance of the task both before and after the sleep period. The same test was conducted with the control group at the beginning and at the end of the day, without sleep.

The results showed that the Central part of the brain, was more active in people who were sleeping. In addition, scientists observed improved performance after a night's sleep. These data give an idea about the role of sleep in the process of motor learning that requires memorization of new sequences of movements.

Doyon believes: "Our findings open the door to other research opportunities that can lead us to a better understanding of the mechanisms that take place during sleep and ensure better interaction between key regions of the brain."
