Got Butterflies in your Stomach? π΅βπ« I am super excited to share the first major study of my postdoc @the-ecg.bsky.social ! We report a multidimensional mental health signature of stomach-brain coupling in the largest sample to date π§΅πhttps://www.biorxiv.org/content/10.1101/2024.06.05.597517v1
π Excited to share our latest preprint! π« Using interoceptive psychophysics and quantitative MRI in 200+ people, we find that individual differences in respiroceptive sensitivity & precision correlate with distinct patterns of cortical microstructure.

Research shows breathing can change our exteroceptive & affective perception, but how? Pleased to share our latest study, led by my PhD student Malthe BrΓ¦ndholt w/ Daniel Kluger, where we investigated the cognitive mechanisms using computational modeling! π§ π www.biorxiv.org/content/10.1...
Illustration of the two-dimensional thermal grill calibration (2D-TGC) method. (A) The Thermal Grill Psychometric Function (TGPF) is characterized by two independent functions. (B) The first function (Ξ¨), depicted in black, represents an invariant psychometric function, mapping the probability of reporting a burning sensation from 0 to 1 at different cold and warm temperatures. (C) The second function (F), illustrated in purple, delineated how the perception of burning changes depending on different cold and warm temperatures.
Stunning new preprint from @francescafardo.bsky.social and her lab - they developed & validated a 2D adaptive model to estimate the thermal grill illusion - it reliably finds combinations of non-painful cold & warm stimuli that together elicit heat pain! #neuro #psych www.biorxiv.org/content/10.1...

Lots of people know that prehistoric sea turtles got big, but it can be easy to underestimate just how huge these things got. The largest verified specimen of a modern Leatherback turtle weighed in at 1,433 lbs, but this Archelon would have been closer to 11,300 lbs. #scicomm #paleosky #paleontology

Pregnancy involves dramatic changes in the body and mind, but we know little about how the self changes, or the cognitive processes underlying this changing self. Check out my new preprint with @rebeccanineill.bsky.social and Sharna Jamadar where we aim to find out: osf.io/preprints/psyaβ¦ A π§΅

Figure 4, which shows the lowest levelised cost of electricity by year and region. Red is solar and becomes predominant in 2027.
A study in Nature Communications finds that a global irreversible solar tipping point may have passed where solar energy gradually comes to dominate global electricity markets, without any further climate policies. go.nature.com/3Mhj4aT
Many researchers in cognitive neuroscience and deep learning seem to assume that inference in the brain is hierarchical.Β
Our new Nature Reviews Neuroscience paper questions this assumption and proposes the shallow brain hypothesis.

#HiSciSky #neuroskyence #PsySciSky Hi all! I'm a professor in cognitive science at the Technical University of Darmstadt. My group studies visual perception using psychophysics and computational modelling. You can learn more about our research here: www.psychologie.tu-darmstadt.de/perception/h....

Hello world of #neuroskyence
I like brains and how they interact with peripheral rhythms like #respiration and #gastric activity. Looking forward to open discussions on all things #bodybrain
Many psychophysics & brain mapping studies use small samples. This often deeply confuses editors & reviewers trained on population statistics. It can also make it difficult to preregister & interpret such studies. Here we attempt to change that:

Hi there #PsychSciSky, #Neuroskyence, #Neuroimaging! My lab studies the computational and cognitive neuroscience of pain, with some intersections with interoception and metacognition thanks to our proximity to @mgallen.bsky.social. Excited to catch up with ex-twitter friends and make new ones here π€
Right, that makes sense! This was all completely new and surprising to me.
Thank you for clarifying that article! Afaik, the 30% statistic is based on a study from the WHO, not on their case study. And it's completely right that this is based on data from developing countries, and so isn't as much of a concern in the us π
