Book excerpt: The brain is made of billions of functional units that interact and give raise to its collective properties. The criticality hypothesis states that many these properties emerge due to brain dynamics operating at the critical point of a phase transition. In models, the critical point maximizes potentially useful properties such as sensitivity, temporal integration, and correlation length. The hypothesis remains controversial, however, in part due to sampling effects: only a small fraction of the neurons in the brain can be recorded, leading to bias in the observed collective properties. In t...
