Control for Epilepsy Suppression: A Mathematical Treatise

What if we could finally stop epilepsy not by cutting the brain or drowning it in drugs, but by speaking its own mathematical language?

This book is the first to treat epilepsy as a pure control-engineering problem. It starts with your brain as a living graph-nodes, wires, white-matter highways-and shows exactly how seizures follow the hidden roads revealed by spectral graph theory and the Laplacian eigenvalue λ₂. It moves into dynamic linear state-space models that let us watch effective connectivity change second by second. Then it dives deep into the famous Epileptor equations, explaining in plain terms how the slow "permittivity" variable z quietly drags the brain across a bifurcation into chaos, and why ordinary EEG misses the vital DC shifts that announce the coming storm.

You'll meet Kuramoto oscillators that explain hypersynchrony, Lyapunov exponents that measure the terrifying loss of complexity before a seizure, critical slowing down as nature's universal early-warning signal, Kalman filters that let implants "see" hidden deep foci, network controllability Gramians that reveal which single electrode can rule the whole network, and real optimal-control recipes (LQR, MPC, sparse LASSO control) that stop seizures with the absolute minimum current-protecting both battery and brain tissue. Every chapter gives you the core formulas, biological meaning, and practical ways to turn theory into tomorrow's closed-loop neurostimulators.

No other book bridges the gap like this. Popular epilepsy books stay at the patient-story or drug level. Classic neuroscience texts stop at beautiful models but never reach actual control design. Engineering control books ignore the wet, plastic, chaotic reality of brain networks. This one refuses to choose sides: it drags spectral graph theory, bifurcation analysis, phase-locking metrics, chaos measures, and modern network control theory into the epilepsy clinic and shows-step by step, equation by equation-how to build devices that predict, prevent, and gently abort seizures instead of just reacting when it's almost too late. It is written for neurologists who want to understand the math, for engineers who want to save patients, and for researchers who believe the next revolution in epilepsy treatment will be mathematical.
