Voxel-based state space modeling recovers task-related cognitive states in naturalistic fMRI experiments (Zhang et al., Front. Neuro., 2021)
May 1, 2021
We present a voxel-based state space modeling method for recovering task-related state spaces from fMRI data. Applied to a visual attention task and a video game task, each task induces distinct brain states that can be embedded in a low-dimensional state space that reflects task parameters.
