My research group is looking for a postdoctoral fellow to study control principles between human-human and human-agent pairs. Ad below. Please retweet!

How can we measure how the nervous system knows, moment to moment, where the body is as it moves?
We introduce a continuous tracking task to measure the hidden dynamics of proprioception—revealing it is faster and more precise than vision during motion.

Fun collaboration with @andpru @AntoineComite @hariteja11 on the merits of infinite horizon control model: how does the brain select a movement time?
Infinite horizon control captures modulation of movement duration in reaching movements biorxiv.org/content/10.1101/…
Preprint alert 🚨:Measured and modelled transitions between self-paced walking and synchronization with rhythmic auditory cues
👇
biorxiv.org/content/10.1101/…
Here we show how these changes in control strategy are modulated by auditory inputs and how they can be simulated in theory: the model suggests that the change is really fast (1 stride?) but the consequence is only visible after long stride series...
In Munich for the 2nd European Motor Control Conference, many thanks to the organisers ! @franklin_lab
I don't know the media and I did not fact check all things that I don't know for sure, but I've witnessed much of what is described here, and we're in trouble: 👇

A very cool new finding from our lab! During a cooperative sensorimotor task, we show that involuntary visuomotor feedback responses reflect a representation of a partner. biorxiv.org/content/10.1101/…

In Maastricht for @ISPGR, come check our work this afternoon ! P02-M-100 by Clémence Vandamme
Important review on cerebellar circuits, however the theoretical basis is wrong: the obvious error is that feedback driven controllers do perform very well even with long delays, if there is a **state estimator**. There is extended literature on computational and behavioural...

Where is the catch? State estimation uses internal models, which if inaccurate produce errors and unintended movement deviations. What do movement errors indicate: wrong IM in the feedback loop or inadequate FF control? We don't know !
Lab outing, visits, outdoors, science, food and lots of fun ! Group pic credit @delhayeben, & Bouillon castle 👇
🚨Tweeprint by @hariteja11 for our work on neural population dynamics: we show that features of neural population activity during reaching emerge from a simple linear body-network system 🧵👇
