WebTo prepare the data for a parametric modulation analysis, we will create a preprocessing pipeline similar to the one we used for the example dataset here. If you haven’t already, go through the tutorial with the Flanker dataset; there you can find the details of each preprocessing and statistical analysis step, which we won’t discuss here in depth. WebApr 13, 2024 · In functional magnetic resonance imaging (fMRI) studies of episodic memory encoding, increased activity in DMN regions even predicts later forgetting in young healthy adults. This association is attenuated in older adults and, in some instances, increased DMN activity even predicts remembering rather than forgetting.
