Naji Alnagger, a PhD candidate of the Coma Science Group, stated: "In order to understand any dynamical system, in this case the brain, it’s often useful to perturb it. Imagine if you want to understand how viscous a liquid is, in other words, its dynamics, you could poke it. By observing how it reacts to the perturbation, how long it takes to return to baseline and the degree it is disturbed could reveal a lot of information as to the viscosity. The same is true here, observing how the model reacts after introducing an artificial perturbation can tell us about the nature of dynamics of the brain activity."
