New paper out in Science Advances!


In this study, we uncover a spatiotemporal complexity architecture of spontaneous brain activity – a human “complexome” that is tightly linked to the brain’s organization as a large-scale network.

The key observation is that the brain operates in distinct states of complexity. Specifically, we found that brain activity is highly irregular most of the time, which is reflected by a higher degree of complexity. However, this “default state” is repeatedly interrupted by spontaneous episodes of low complexity (“complexity drops”), in which brain activity becomes much more regular for a short moment in time.

These dynamics offer an explanation for why brain areas interact in functional networks and how activity patterns spread across the brain over time. Furthermore, the approach explains how brain networks change on the scale of seconds to minutes and creates a link between functional and anatomical properties of brain regions. Moreover, our work also shows that neural complexity is linked to age as well as cognitive and motor performance.

Baby brains! New preprint on the formation of brain shape in human newborns!


The human brain undergoes a phase of critical structural developments around birth. In our new study, we show that this perinatal development comes with a rapid formation of brain shape, beyond the expected growth in brain size.

Specifically, brain shape allowed us to predict the age of the infants from structural MRI data with a mean error of only ~4 days, systematically outperforming age prediction from brain size. Moreover, brain shape detected persistent signatures of premature birth that were not detected by brain size. Furthermore, we found that the brains of genetically related infants are more similar in shape than they are in size. Additionally, this shape similarity allowed us to predict which newborns are twin siblings with up to 97% accuracy, again outperforming twin predictions from brain size.

Preprint on functional connectivity fingerprinting


Preprint – Fingerprinting and behavioural prediction rest on distinct functional systems of the human connectome

New preprint on the relation between functional connectome-based identification and behavioural prediction! Based on high-quality resting-state fMRI, we find a dichotomy of signatures underlying the identification of individuals and the prediction of behaviour. The dichotomy is apparent on all levels of analysis, looking at  individual connections, resting-state networks and topological distribution. Find the preprint here!

New article in NeuroImage: Clinical: Transdiagnostic analysis reveals a shared hippocampal damage pattern across neuroimmunological diseases


New article in NeuroImage: Clinical: Transdiagnostic analysis reveals a shared hippocampal damage pattern across neuroimmunological diseases

Our recent article shows that hippocampal surface deformations converge on the left anterior hippocampus in patients with multiple sclerosis, NMDA receptor encephalitis and LGI1 encephalitis. This surface area appears to be particularly vulnerable across diseases and is sensitive to cognitive alterations.

Discover the spatial patterns in our full-text here.
