Fmri activity
WebNov 15, 2024 · Activity maps were obtained with fMRI at 3T for the same task in the same participant prior to surgery. We then correlated HFB power with the fMRI BOLD signal change in the area around each electrode. This latter measure was quantified by applying a 3D Gaussian kernel of varying width (sigma between 1 mm and 20 mm) to the fMRI … WebAug 1, 2014 · A form of MRI known as functional MRI (fMRI) has emerged as the most prominent neuroimaging technology over the last two decades. fMRI tracks changes in blood flow and oxygen levels to indicate neural activity. When a particular brain area is more active, it consumes more oxygen, and blood flow increases.
