Method for measuring neurovascular uncoupling in fMRI

摘要

Neurovascular uncoupling that causes fMRI data to underestimate viable neuronal activity in the brain is detected and indicated to assist in pre-surgical planning. Tasks associated with the cortical region in question are performed while the fMRI measurement of brain activity is measured and the same tasks are performed while task performance is measured directly. Neurovascular uncoupling is detected and indicated by comparing the results of fMRI measurement and direct measurement.
