Structure-function interplay as signature for brain decoding and fingerprinting
[article]
2021
bioRxiv
pre-print
Preserved Fulltext
Here, we leveraged brain structure-function coupling as a new imaging-based biomarker to characterize tasks and individuals. ...
Brain signatures of functional activity have shown promising results in both decoding brain states; i.e., determining whether a subject is at rest or performing a given task, and fingerprinting, that is ...
