WebGRF theory requires that we know the spatial correlation, at least approximately. In order to meet this requirement, we must do fairly hefty spatial smoothing (i.e., precoloring). This has the obvious disadvantage of blurring together brain structures with different functions, particularly if the smoothing is not done on the cortical surface. WebfMRI is special, in the sense that the data lend themselves to a signal processing perspective. This can be exploited to ensure that both the design and analysis are as efficient as possible. Linear time invariant models provide the bridge between inferential models employed by statistical mapping and conventional signal processing approaches. the pressure of oxygen in units of atm https://dvbattery.com
