Independent Component Analysis (ICA) can identify patterns in fMRI data. Some of the components reflect BOLD signal and others are driven by noise. This post explains how to identify signal components and noise components in your data.
In resting-state fMRI processing we often apply Independent Component Analysis to clean the data from noise. Automated approaches for ICA-based cleaning can automatically label components as noise or signal, but often need to be trained on data-specific labels. This post explains how to train an automated ICA component classifier and use it to denoise fMRI data.
During the Western Brainhack 2022, we built a Functional Atlas Explorer. The web-based app allows the user to explore functional regions in the cerebellum. Selecting a cerebellar regions gives a task profile (which functions is this region involved in?) and a connectivity profile (which cortical regions are functionally connected to this cerebellar region?).
In recent years, the cerebellum has been increasingly implicated in both cognition and clinical conditions. These findings views of the cerebellum as a purely motor structure. By reviewing recent advances in mapping cerebellar function social, …

Guide to creating and using fieldmaps to correct MRI data for B0 field inhomogeneities. Particularly focussed on visual inspection and troubleshooting, as there are a few pitfalls when doing fieldmap correction.
