WebOur results revealed significantly greater activation during subtraction in regions along the dorsal pathway, including the left inferior frontal gyrus (IFG), middle portion of dorsolateral prefrontal cortex (mDLPFC), and supplementary motor area (SMA), compared with addition.
WebfMRI: subtraction method. BOLD signal across two conditions is contrasted ex) compare activity seen when using your left hand to activity seen when using your right hand by subtracting the signals For example, we might compare the BOLD signal in an area of voxels when a patient views faces to when a patient views scrambled faces.

Another limitation on experimental design is head motion, which can lead to artificial intensity changes of the fMRI signal. In a block design, two or more conditions are alternated by blocks. Each block will have a duration of a certain number of fMRI scans and within each block only one condition is presented. By ma… solbin and jinWebThe first method was motivated by the desire to identify significant regions of brain activation using fMRI coordinate-based meta data. To identify these regions we elected to implement a Bayesian spatial Cox process.
