There is going to be an exiting workshop on advanced fMRI end of October in Erice, Sicily (Italy).

The agenda looks just at great as the location.

Häkkinen et al., investigated how to push layer-fMRI VASO at the next-Gen 7T (Feinbergatron) 7T scanner for layer-specific circuitry mapping. The fast gradients reveal temporal dynamics and connectivity with the cortex.

Beautiful paper by the brilliant @jhaarsma.bsky.social exploring how false and veridical percepts converge and diverge. Turns out both share content-specific and confidence signals; and hellohello pre-stimulus alpha... what are you up to with false percepts?

New MEG paper by @jhaarsma.bsky.social and @dotproduct.bsky.social‬! Same design and behavioural results as our 7T layer fMRI study (www.jneurosci.org/content/43/4...), but now shedding light on the temporal dynamics of the sensory signals underlying false percepts. #neuroskyence

Shared and diverging neural dynamics underlying false and veridical perception

We often mistake visual noise for meaningful images, which sometimes appear as convincing as veridical percepts. This suggests considerable overlap between the mechanisms that underlie false and verid...

🚨🚨🚨PREPRINT ALERT🚨🚨🚨
Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!

Overview of the simulation strategy and analysis. a) Pial and white matter boundaries
surfaces are extracted from anatomical MRI volumes. b) Intermediate equidistant surfaces are
generated between the pial and white matter surfaces (labeled as superficial (S) and deep (D)
respectively). c) Surfaces are downsampled together, maintaining vertex correspondence across
layers. Dipole orientations are constrained using vectors linking corresponding vertices (link vectors).
d) The thickness of cortical laminae varies across the cortical depth (70–72), which is evenly sampled
by the equidistant source surface layers. e) Each colored line represents the model evidence (relative
to the worst model, ΔF) over source layer models, for a signal simulated at a particular layer (the
simulated layer is indicated by the line color). The source layer model with the maximal ΔF is
indicated by “˄”. f) Result matrix summarizing ΔF across simulated source locations, with peak
relative model evidence marked with “˄”. g) Error is calculated from the result matrix as the absolute
distance in mm or layers from the simulated source (*) to the peak ΔF (˄). h) Bias is calculated as the
relative position of a peak ΔF(˄) to a simulated source (*) in layers or mm.

Our study using layer fMRI to study the direction of communication between the hippocampus and cortex during perceptual predictions is finally out in Science Advances! Predicted-but-omitted shapes are represented in CA2/3 and correlate specifically with deep layers of PHC, suggesting feedback. 🧠🟦

Communication of perceptual predictions from the hippocampus to the deep layers of the parahippocampal cortex

High-resolution neuroimaging reveals stimulus-specific predictions sent from hippocampus to the neocortex during perception.

Nottingham Forest are only the second side in Premier League history to lose a game by 5+ goals and then follow it up by immediately winning their next game in the competition by 5+ goals.

Who was the first?
