FMRI is increasingly being used in presurgical planning
in patients with brain tumors and epilepsy to facilitate
resection of affected tissue without harming essential
function. In clinical populations, the HRF may be
modified in regions of pathology. Being model-free,
reproducible and able to automatically identify and
remove unreliable runs from the analysis, uNBIASED may
aid identifying neuronal activation when poor
performance or artifact contamination is present, or the
response does not agree with the prediction due to
compromised performance or modified hemodynamic
coupling.
