Stats on #bodybrain #neuroskyence data can become non-trivial pretty quickly: Anything beyond t-tests on 'systole vs diastole' or 'insp vs exp' will include some form of phase binning, so we need adequate surrogates for robust permutation stats. Plus, these are not available for circular data.

New preprint from the lab! 🧠
Led by Juliana Trach, w/ Sophia Ou

Using fMRI, we discovered evidence for time-sensitive reward prediction errors (RPEs) in the human cerebellum.

Builds on, and extends, recent work in both rodents and NHPs

Motor prediction reduces beta-band power and enhances cerebellar-somatosensory connectivity before self-touch to enable its attenuation Prevailing theories suggest that the brain uses an internal forward model to predict tactile input during voluntary movements, thereby reducing the intensity of the reafferent tactile sensation, a phe...

📣 New preprint 📣

The brain attenuates self-touch, but how does this unfold at the neural level before the touch? We used MEG to find out 🧠 👉👈

Got Butterflies in your Stomach? I am super excited to share the first major study of my postdoc @the-ecg.bsky.social - Now out in @natmentalhealth.nature.com! We report a multidimensional mental health signature of stomach-brain coupling in the largest sample to date www.nature.com/articles/s44...

A major KI initiative to recruit new assistant professors with outstanding proposals in all areas of medicine, biomedicine and public health. We offer an amazing research environment, great colleagues and generous startup packages. Check it out and get working on your applications! (repost please!)

Preprint time :)
In this one, led by @asanchezcorzo.bsky.social, we describe respiratory coupling to excitability states across the wake-sleep cycle. If only we could always have hours and hours of data... Great first collab with the lab of @tschreiner.bsky.social at LMU! #Neuroskyence 🧠🟦

Somatosensory timing and cerebellar-basal ganglia beta-band interactions in Parkinson's disease https://www.biorxiv.org/content/10.1101/2025.05.15.653735v1

In conclusion, investigating PD-participants can reveal both underlying facts of our timing and action networks, while also shedding light on the disease itself.

As an exploratory endeavour, we investigated the cerebello-thalamo-ganglion network we, proposed in bit.ly/42Yh4NE, and found that PD-patients showed altered activity for the jittered condition.

The differences in the cerebellum correlated with PD-symptoms as measured by UPDRS.

Before the onset of the expected, but omitted stimulation, we found differences in the beta band (14-30 Hz) between groups in the cerebellum and the caudate nucleus.

We had PD-participants and controls participate in a passive paradigm. Jittered and non-jittered trains of stimulation were followed by omissions.

Somatosensory timing and cerebellar-basal ganglia beta-band interactions in Parkinson’s disease Parkinson’s disease has traditionally been viewed through the lens of basal ganglia dysfunction, yet emerging research also implicates the cerebellum and its connections to the basal ganglia. To prob...

Parkinson’s disease is all about basal ganglia, right?

Using MEG in a timing paradigm, we find altered PD-activity in the cerebellum as well. This is important for understanding timing and action networks in the brain and sheds light on PD. @pandonaude.bsky.social 🧠📈

I’m looking for a postdoc and RA for an ERC-funded project “SLEEPAWAY: Forgetting unwanted memories in sleep”. You’ll use MEG/EEG and fMRI to understand how the sleeping brain remembers and forgets. PLEASE REPOST 😊

🧠 Det er reptilhjernen, der får dig til at jagte sex, mad og vold…troede du måske?

Faktisk er myten om krybdyrhjernen punkteret. Hør hvorfor i podcasten ’Forskernes fredagsbar’ med lektor i kognitionsvidenskab Lau Møller Andersen. - www.spreaker.com/episode/sada...

Could you expand on what those other things are?
I am curious because, in humans, we are finding out that the cerebellum is basically involved in most cognition as well.
And I am eager to learn what might be going on in other species.

Thanks

The cerebellum is part of the reptile brain, right?
Listen to me debunk this myth that's alive and kicking outside the neuroscience circles in this popular science podcast (in #Danish)

Coming back to my job call, this is exactly what I set out to test using a combination of deep brain stimulation and magnetoencephalography. 🧠📈
international.au.dk/about/profil...

This fits with our second paper, short review where we forward the hypothesis that the cerebellum is not a time-keeper per se, but an integrator of spatial and temporal information that can inform predictions about future sensory events, and allowing for informed behaviour bit.ly/4bcQd31. 🧠📈

Thus, we find a cerebellum-behaviour correlation that we interpret as: the more surprising the stimulus is to the cerebellum, the less likely one is to detect it. We also find evidence of connectivity between cerebellum and thalamus which we interpret as the cerebellum informing one’s action plans🧠📈

n Detection of ..., we (
@sarangnemo.bsky.social

) find cerebellar evoked responses to threshold-level stimuli. We find that accuracy in detection correlates with the magnitude of the cerebellar response, which is in turn dependent on the temporal regularity of preceding stimuli bit.ly/3D2AlTR 🧠📈

Background: when going off X/Twitter, I got out of habit of promoting my articles online. I’d like to highlight two articles on the cerebellum that I published in 2024, which also provides some context to my current call. I’m excited about revealing a cerebellum-behavioural correlation
