Before revision:  We propose here two such controls, and show that the Fontenele test can misclassify as critical these non-critical systems . This implies that the analyses of Fontenele et al. do not support their conclusions, and the question of whether the brain operates at criticality remains open .
After revision:  We propose here two such controls, and show that the Fontenele test can misclassify as critical these non-critical systems pass all the tests for criticality, a control that was not provided in the original article. We conclude that such false positives demonstrate that the presence of criticality in the brain is still not proven and that we need better methods that scaling analyses .
