Introducing a new method by Johan Medrano from the FIL Methods Group, for inferring gradual changes in synaptic gain, using M/EEG data and DCM. Find out more at #OHBM2024@johmedr.bsky.socialww6.aievolution.com/hbm2401/inde...

Detail of the poster abstract. (a) Picture of a neural mass model with 2 interlinked brain regions, (b) Formulae for a design matrix X that scales connection strengths beta over time. (c) Illustration of a design matrix using that uses DCT basis functions to capture slow modulation of connection strengths. Medrano et al. 2024

The new Google Scholar PDF reader plugin for Chrome seems very good indeed. You can click a link to a reference and then press back to return to the text 🤯 Hope it lasts.

In principle, you could use a model that has the amount of spatial sparsity parameterised within it, to explicitly test punctate vs distributed hypotheses. Multivariate Bayes (MVB) is one such (decoding) model in SPM. Not so commonly used. See www.jiscmail.ac.uk/cgi-bin/weba...

A personal bugbear: reporting evidence for effect A, and no evidence for effect B, then claiming there's a difference between A and B, without having compared them
