What can disrupted timing in brain signals tell us about it's cognitive control systems and #ADHD?
New research has found that polygenic scores for ADHD can predict irregularities from the frontal areas of the brain.

Increasing IAF via NF enhances attention & speeds up alpha-ERD onset www.sciencedirect.com/science/arti...
Cool convergence in recent alpha work; frequency setting the timing of cortical engagement in attention, and power relating to how well info is represented + whether it's accessed in memory 🌊
The supply of blood to brain tissue is thought to depend on the overall neural activity in that tissue, and this dependence is thought to differ across brain regions and across brain states. However, studies supporting these views have measured neural activity as a bulk quantity and related it to blood supply following disparate events in different regions. Here we measure fluctuations in neuronal activity and blood volume across the mouse brain, and find that their relationship is consistent across brain states and brain regions but differs in two opposing brainwide neural populations. Functional ultrasound imaging (fUSI) revealed that whisking, a marker of arousal, is associated with brainwide fluctuations in blood volume. Simultaneous fUSI and Neuropixels recordings showed that neurons that increase activity with whisking have distinct haemodynamic response functions compared with those that decrease activity. Their summed contributions predicted blood volume across states.Brainwide Neuropixels recordings revealed that these opposing populations coexist in the entire brain. Their differing contributions to blood volume largely explain the apparent differences in blood volume fluctuations across regions. The mouse brain thus contains two neural populations with opposite relations to brain state and distinct relationships to blood supply, which together account for brainwide fluctuations in blood volume.
How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states!

Graphical abstract showing three panels. Left panel, "Multiorgan Interoception Measures," depicts a translucent human body silhouette with anatomically rendered heart (red) and lungs (blue), accompanied by schematic icons for three psychophysical tasks: the Respiratory Resistance Sensitivity Task (RRST), Heart Rate Discrimination Task (HRDT), and an auditory control condition. N = 241 participants. Center panel, "Psychophysical Modelling and Individual Differences," shows a fan of overlapping sigmoid psychometric curves in blue-to-red gradient representing individual variation in perceptual threshold (α) and precision (β), a hierarchical Bayesian model diagram, and icons for metacognitive bias and M-Ratio efficiency. Right panel, "Key Finding: No Cross-Modal Relationship," displays a scatterplot of cardiac versus respiratory sensitivity with a flat regression line (r ≈ 0, BF₀₁ > 6), a compact Bayes Factor heatmap with mostly blue null-supporting cells and one orange cell indicating that subjective confidence is shared across modalities (r = 0.51***). Takeaway: interoceptive ability is modality-specific.
Is there a single "interoceptive sense"? Our new study in
@commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪

It's been interesting to think about this very cool paper in the context of @darya-frank.bsky.social's work on how sensitivity to novelty & expectation violations relates to strengthening of episodic memories in superagers - after hearing her awesome talk this week @yorkpsychology.bsky.social 🧠

Thank you Catherine! 🍾
Thank you! 😊
Delighted to share that I'll begin a postdoc in Tübingen this year 🇩🇪 on @joelfrohlich.bsky.social's exciting FETAL-MIND project; using fMEG & OPM to investigate neural responses to sensory and social stimuli, in the fetal brain! 🧠
How dynamics arise from the structure is my biggest interest. In this study, we started with a small step and asked how structure constrains dynamics. Spoiler: would that it were so simple… (1/6)
