Modelling the multiregional dynamics of stimulated brain networks
This issue highlights a mathematical model for quantifying the sensitivity of patients with cancer to checkpoint inhibitors, the identification of subtypes of psychiatric disorders from functional-connectivity patterns in resting-state electroencephalography, the prediction of multiregional brain-network dynamics in response to direct electrical stimulation, computational modelling for the optimization of treatment schedules for glioblastoma, and the identification of converging genetic and epigenetic drivers of paediatric acute lymphoblastic leukaemia via an information-theory analysis of DNA methylation.
The cover illustrates the predicted dynamics of large-scale brain networks during direct electrical stimulation.

The availability of higher-quality biomedical and clinical data is widening the reach and usefulness of data-fitted biophysical models and of data-driven mathematical and statistical modelling.
The dynamics of multiregional brain networks in response to temporally varying patterns of ongoing direct electrical stimulation can be predicted by modelling, with variabilities in prediction accuracy explained by at-rest functional connectivity.
The time course of tumour responses to immunotherapies can be mathematically predicted on the basis of tumour-growth rates, the rates of immune activation and of tumour–immune-cell interactions, and the efficacy of immune-mediated tumour killing.
A mathematical model of the time course of tumour responses to immunotherapy predicts tumour burden and treatment sensitivity across cancer types and drug combinations.
Two clinically relevant subtypes of post-traumatic stress disorder and major depressive disorder have been identified via machine learning analyses of functional connectivity patterns in resting-state electroencephalography.
Input–output models can predict multiregional brain network dynamics in response to temporally varying patterns of ongoing direct electrical stimulation, with variabilities in prediction accuracy explained by at-rest functional connectivity.
A computational model of the spatiotemporal dynamics of the perivascular niche that incorporates relevant cellular and tissue-level phenomena can be used to optimize treatment schedules for glioblastoma.
An information-theoretic analysis of DNA methylation in samples from patients with paediatric acute lymphoblastic leukaemia reveals that a regulatory set of driver genes harbour the greatest differences in methylation stochasticity.
