Discriminant Spatial Filtering Method (DSFM) for the identification and analysis of abnormal resting state brain activities

作者:

Highlights:

• Identification of discriminant regions is vital for feature selection.

• Discriminant spatial filtering helps identify abnormal neural activities using fMRI.

• Discriminant spatial projection improves separability and classification accuracy.

• Disruption of DMN and frequent shifts in attention were observed in ADHD patients.

• DSFM classifier achieves a 73.83% classification accuracy over the ADHD200 dataset.
