Abstract: We propose a structured framework for the application of recurrent deep learning (DL) models to the analysis of fMRI data. To identify an association between cognitive state and brain activity, DeepLight utilizes the layer-wise relevance propagation method. Thereby, decomposing the DL model’s decoding decisions into the contributions of the single input voxels to these decisions. Importantly, DeepLight is able to identify this association on multiple levels of data granularity, from the level of the group down to single subjects, trials and time points.
