Perturbing a Neural Network to Infer Effective Connectivity: Evidence from Synthetic EEG Data

no code implementations19 Jul 2023 Peizhen Yang, Xinke Shen, Zongsheng Li, Zixiang Luo, Kexin Lou, Quanying Liu

Specifically, we trained neural networks (i. e., CNN, vanilla RNN, GRU, LSTM, and Transformer) to predict future EEG signals according to historical data and perturbed the networks' input to obtain effective connectivity (EC) between the perturbed EEG channel and the rest of the channels.

Mapping effective connectivity by virtually perturbing a surrogate brain

1 code implementation31 Dec 2022 Zixiang Luo, Kaining Peng, Zhichao Liang, Shengyuan Cai, Chenyu Xu, Dan Li, Yu Hu, Changsong Zhou, Quanying Liu

Effective connectivity (EC), indicative of the causal interactions between brain regions, is fundamental to understanding information processing in the brain.

Online Learning Koopman operator for closed-loop electrical neurostimulation in epilepsy

no code implementations26 Mar 2021 Zhichao Liang, Zixiang Luo, Keyin Liu, Jingwei Qiu, Quanying Liu

In this work, rooted in optimal control theory, we propose a Koopman-MPC framework for real-time closed-loop electrical neuromodulation in epilepsy, which integrates i) a deep Koopman operator based dynamical model to predict the temporal evolution of epileptic EEG with an approximate finite-dimensional linear dynamics and ii) a model predictive control (MPC) module to design optimal seizure suppression strategies.
