My first 2 weeks as a postdoc at @unituebingen.bsky.social have been a delight! 🇩🇪 If you're interested in our fetal MEG system or research on sensory & social processing in utero, take a look at @joelfrohlich.bsky.social's shiny new website: fetalmeg.org/academics 🧠

This study shows that individual brain rhythms play an important role in how we process speech. People with strong auditory-motor synchronization may benefit more from the interaction between auditory and motor brain systems, while others rely more on their auditory system and working memory.

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! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social
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.

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 🧪
  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.
