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/…

Infinite horizon control captures modulation of movement duration in reaching movements

Movement duration, a fundamental aspect of motor control, is often viewed as a pre-programmed parameter requiring dedicated selection mechanisms. An alternative view posits that movement duration...

This is not so clear... In fact the evidence that we have for finite horizon control in the sensorimotor system may not be what we think ! Especially, the effect of rewards and nonlinearities modulate feedback gains in finite and infinite horizons schemes...

Preprint alert 🚨:Measured and modelled transitions between self-paced walking and synchronization with rhythmic auditory cues 👇 biorxiv.org/content/10.1101/…

Measured and modelled transitions between self-paced walking and synchronization with rhythmic...

Constraining gait rhythm with a metronome has been shown to influence gait pattern in many different ways. While rhythmic cues can improve several parameters in some clinical populations, they do...

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...

The computational approach developed here could be a powerful mean to assess goal-directed changes in gait control in clinical populations... (stay tuned ! 😉 )

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/… Led by the extremely talented, @SethSullivan_

Involuntary feedback responses reflect a representation of partner actions

We have a remarkable ability to seamlessly and rapidly coordinate actions with others, from double dutch to dancing. Humans use high-level partner representations to jointly control voluntary...

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 !

Besides: critical damping as shown in Fig. 1 of the paper can be achieved without FF controller (depends on the mechanical parameters...)

🚨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 🧵👇 biorxiv.org/content/10.1101/…

Neural Population Mechanisms for Flexible Sensorimotor Control

Modern large-scale recordings have revealed that motor cortex activity during reaching follows low-dimensional dynamics, thought to reflect sensorimotor computations. However, the origin of these...

🧠What do random neural networks have in common with the motor cortex? Turns out, a lot! Both exhibit similar low‑dimensional dynamics across sensorimotor tasks.👇🧵

This simple model (1) explains a lot of data, (2) makes direct prediction about population activity and low dimensional factors for any task and (3) provides a conceptual framework linking neural population activity and sensorimotor control...

d) We spend too much time doing things and too little time thinking about it. Lets publish fewer papers. We can do that.
