Scale-specific analysis of fMRI data on the irregular cortical surface
2018
NeuroImage
14 To fully characterize the activity patterns on the cerebral cortex as measured with fMRI, 15 the spatial scale of the patterns must be ascertained. Here we address this problem by 16 constructing steerable bandpass filters on the discrete, irregular cortical mesh, using an 17 improved Gaussian smoothing in combination with differential operators of directional 18 derivatives. We demonstrate the utility of the algorithm in two ways. First, using 19 modelling we show that our algorithm yields
