Thx for the clarification!
E.g. here: "Under normal physiological conditions, the cupula is completely attached around its periphery and precludes the movement of endolymph from one side of the ampulla to the other (Hillman 1974; McLaren and Hillman 1979; Rabbitt et al. 2009)."

Hey Jean, just wondering: I always thought the cupula mostly blocks the canal and while inertia leads to the liquid deforming the cupula, it cannot start flowing past it (as it seems in your videos). Furthermore, I thought the aftereffect comes from a neural velocity storage. Is that wrong/outdated?
We had the pleasure of welcoming Dr. Lorenz Assländer (Uni Konstanz) to our #DHPRlab meeting.
He spoke about the cybernetics of human balance -how the nervous system integrates sensory cues to maintain stability- and about Augmented Visual Orientation Cues technology.
Thank you, @cybal.bsky.social🙏
Wir gratulieren! Lorenz Assländer @cybal.bsky.social und Matthias Albrecht von der #UniKonstanz erhalten den Dr. K. H. Eberle Preis 2025 für eine innovative Augmented-Reality-Brille, die das Gleichgewicht älterer Menschen und neurologischer PatientInnen verbessern soll. Details: t1p.de/jcafk
Two posts from Bluesky. The first one shows a figure from a paper published in Nature Scientific Reports full of totally incoherent AI fabricated gibberish words. The other a comment on a recently published paper by eLife discussing the paper and its peer reviews which were published along with the paper.
Nature Sci Rep publishes incoherent AI slop. eLife publishes a paper which the reviewers didn't agree with, making all the comments and responses public with thoughtful commentary. One of these journals got delisted by Web of Science for quality concerns from not doing peer review. Guess which one?
📺 In the German primetime TV show JENKE Experiment, participants endured three hours of boredom - with a few theory-driven curveballs 😁
A vivid reminder that doing “nothing” can be tough & that boredom really matters.
Very excited to have contributed to this project.

In 1916 the BMJ published an article about the work done by James Shearer, an American physician working in the British Army as a sergeant (because he had no British qualification). He had described a "delineator" which was better than x rays for portraying gunshot wounds. This caused a sensation and a lot of interest — but on investigation the work was found to have been invented. The BMJ published a retraction, but Shearer was tried by court martial and sentenced to death by firing squad.
Next time an institution tells you how seriously it takes research misconduct, ask them if it's *this* seriously. www.bmj.com/content/297/...

We have an open rank, tenure-line faculty position in biomechanics in the School of Kinesiology at the University of Michigan Ann Arbor. At U-M we have great colleagues, exceptional resources, and biomechanics can be found all across the campus. #BiomechSky
Fully agree! Visual, vestibular and also proprioceptive sensory systems all have prominent velocity signals.
Paper was recently featured in J Neuroscience; author copy through OSF.

Our data is from sway behavior during standing balance. We believe the mechanism is generally relevant for the internal reconstruction of body orientation and #selfmotion for #motorcontrol, #perception, and #navigation.
In a linear system, visual scene motion evokes body sway at just those frequencies contained in the scene motion. We predicted a distortion using simulations, where body sway is evoked at frequencies NOT contained in the scene motion. This non-intuitive prediction was confirmed in experiments.
This reflects a reduced reliance on vision, quantitatively reproduced by the RFM mechanism.
Furthermore, the RFM model - once tuned - also predicts sway in new sequences (Prediction).
A typical behavior is that subjects sway increases less than proportional when increasing the movement amplitude of the visual reference: the 'gain' (amplitude ratio between body sway and stimulus) is reduced with increasing stimulus amplitude (Model fit left-to-right).
We implemented this mechanism in a closed-loop balance control model and compared its behavior with the sway responses of 24 subjects viewing a moving visual screen in a virtual reality head-mounted display.
The magic comes in, when assuming that the RFM reconstruction is blocked at small velocities and corrects (= is added to) the visual self-motion signal when exceeding a certain velocity threshold.
Why magic? It explains human behavior related to context dependent changes in sensory contributions.
In our new paper, we present evidence that the CNS continuously estimates the movement of the visual reference by comparing visual to other sensory cues. This reconstruction of Reference Frame Motion (RFM) happens in velocity. Why?
The underlying question is a fundamental problem in neuroscience: how does the nervous system construct body orientation from multiple, potentially conflicting sensory inputs?
We might have a solution.
Is it me, or the train moving?
We use vision to maintain balance. Just close your eyes while standing on one leg and you typically feel less stable. But if we use vision, how come we do not fall when looking at a moving visual reference, e.g. a train?

Interesting paper, thread and discussion!
Germany has this DEAL consortium, which currently is focused on promoting Open Access. Would be cool to push this towards non-profit journals only.

Brain Surfaces of 70 primate species

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!
