abstract = {Individualized anatomical information has been used as
prior knowledge in Bayesian inference paradigms of
whole-brain network models. However, the actual sensitivity
to such personalized information in priors is still unknown.
In this study, we introduce the use of fully Bayesian
information criteria and leave-one-out cross-validation
technique on the subject-specific information to assess
different epileptogenicity hypotheses regarding the location
of pathological brain areas based on a priori knowledge from
dynamical system properties. The Bayesian Virtual Epileptic
Patient (BVEP) model, which relies on the fusion of
structural data of individuals, a generative model of
epileptiform discharges, and a self-tuning Monte Carlo
sampling algorithm, is used to infer the spatial map of
epileptogenicity across different brain areas. Our results
indicate that measuring the out-of-sample prediction
accuracy of the BVEP model with informative priors enables
reliable and efficient evaluation of potential hypotheses
regarding the degree of epileptogenicity across different
brain regions. In contrast, while using uninformative
priors, the information criteria are unable to provide
strong evidence about the epileptogenicity of brain areas.
We also show that the fully Bayesian criteria correctly
assess different hypotheses about both structural and
functional components of whole-brain models that differ
across individuals. The fully Bayesian information-theory
based approach used in this study suggests a
patient-specific strategy for epileptogenicity hypothesis
testing in generative brain network models of epilepsy to
improve surgical outcomes.},
