Tracking Fast Neural Adaptation by Globally Adaptive Point Process Estimation for Brain-Machine Interface

no code implementations27 Jul 2021 Shuhang Chen, Xiang Zhang, Xiang Shen, Yifan Huang, Yiwen Wang

In order to identify the active neurons in brain control and track their tuning property changes, we propose a globally adaptive point process method (GaPP) to estimate the neural modulation state from spike trains, decompose the states into the hyper preferred direction and reconstruct the kinematics in a dual-model framework.
