Abstract: International audience; There is increasing focus on the neurophysiological underpinnings of brain activations, giving birth to an emerging branch of neuroscience - neuroenergetics. However, no common definition of "brain activation" exists thus far. In this article, we define brain activation as the information-driven reorganization of energy flows in a population of neuroglial units that leads to an overall increase in energy utilization in this population. On the basis of this definition, the key aspects of modern biochemical and biophysical...
