Over the last few decades, neuroscience has begun to confirm or refute certain hypotheses we had about how the brain works, in addition to leading us down new paths of knowledge. Given the complexity of this fascinating organ, we are only at the beginning of this promising exploration. However, thanks to brain imaging, we know a little more about some of its particularities at different stages of life and their links with learning.

Our brain is never really at rest. When it is not busy with a specific task, it can daydream or ruminate, depending on our mood, but it never stops being active. This is what neuroscientists have uncovered by discovering the functioning of its so-called "default" network, which is activated in a way that is opposite to the executive network that manages our high-level cognitive processes.

Difficulty concentrating, lack of motivation, mental wandering... Does that sound familiar? Whether these signs appear during a day or more evidently at certain times of the week, month or year, they tell us that we are in need of a break. However, our demanding lives and the performance culture that we struggle to detach ourselves from mean that we ignore them all too often and persist as best as we can in our daily tasks, whether we are a worker or a student.
