  Using functional magnetic resonance imaging (fMRI) and deep learning to
explore functional brain networks (FBNs) has attracted many researchers.
However, most of these studies are still based on the temporal correlation
between the sources and voxel signals, and lack of researches on the dynamics
of brain function. Due to the widespread local correlations in the volumes,
FBNs can be generated directly in the spatial domain in a self-supervised
manner by using spatial-wise attention (SA), and the resulting FBNs has a
higher spatial similarity with templates compared to the classical method.
Therefore, we proposed a novel Spatial-Temporal Convolutional Attention (STCA)
model to discover the dynamic FBNs by using the sliding windows. To validate
the performance of the proposed method, we evaluate the approach on HCP-rest
dataset. The results indicate that STCA can be used to discover FBNs in a
dynamic way which provide a novel approach to better understand human brain.
