The role of dorsal premotor cortex in joint action inhibition - Scientific Reports Scientific Reports - The role of dorsal premotor cortex in joint action inhibition

The third is on how interpersonal motor coordination is regulated via neurophysiological #inhibition. Here we confirm a dissociation between fast and slow inhibition and provide evidence that dorsal #premotor areas are key for motor co-adaptations. t.ly/EJStV

Submovement interpersonal coupling is associated to audio-motor coordination performance - Scientific Reports Scientific Reports - Submovement interpersonal coupling is associated to audio-motor coordination performance

The second is on the multiple time-scales of #interpersonal #motor coordination. Here we demonstrate that submovement coordination is a potentially fundamental mechanism that participates in interpersonal motor coordination regardless of the sensory domain mediating the interaction. t.ly/szd0h

The first is on how motor processes in speech perception. We studied neural encoding (#EEG) of articulatory #synergies during speech listening. With partial information decomposition we described unique #motor information in the theta and delta bands and its dependence on task difficulty. t.ly/9ocuu

What a week this has been! 3 papers out and its still Thursday!
Definitely too much, now I should brace for 6 months of rejections 😀

I have a bunch of things I have to get done, so naturally I decided to procrastinate by making an alignment chart of mathematical models

Brain-wide topographic coordination of traveling spiral waves bioRxiv - the preprint server for biology, operated by Cold Spring Harbor Laboratory, a research and educational institution

Have you wondered whether fast spatiotemporal brain dynamics like traveling waves are local, confined to just one region, or whether they are shared across many regions simultaneously? The latest work from Zhiwen Ye in my lab has the answer! Thread-

This one has a similar vibe, yet with a tiny bit more "evolutionary" and "vintage" flavour ;))

The sole reason our brains have memory is to help us take better decisions and actions in future.

Indeed! I thought you referred to "intra-effector" synergies, but I totally see your point now, and it partially resonates with other stuff we're doing (e.g., tinyurl.com/42a9dwvh ). Thanks for the useful suggestion! I'll let you know if something interesting pops out!

Unfortunately not, but very interesting indeed! …here we only measured the FDI during an index finger ad/abduction. To do that we would probably need a more “complex” task…
Rather, we’re working on cortico-muscle (or better force) coherence in alpha range with great satisfaction ;)

Sad but very true. As for the Italian case, there's one clear reason: the National Scientific Habilitation, introduced in 2012, filters applications based on 3 thresholds (different for each area) on #pub last 5Y, #citations last 10Y, h-index last 10Y.
Classic example of Goodhart's law.

We suggest this may reflect a non-linear mapping between corticospinal excitability and multiscale movement oscillations, potentially linked to the hierarchical organization of descending motor pathways.

Surprisingly, unlike motor output oscillations, which decrease in amplitude as their frequency increases, corresponding changes in corticospinal excitability maintain a similar magnitude across different timescales.

We delivered #TMS over M1 while participants were performing a visuomotor task involving isometric force production and assessed #corticospinal excitability modulation time-locked to task-instructed force modulation, as well as to #submovements and #tremor in the motor output.

Graphical abstract of the paper in Journal of Physiology describing that unlike motor output oscillations, corticospinal excitability (as measured via TMS) spans a similar range across different time-scales. Namely the instructed one at 0.25Hz, that of submovements at 2Hz and that of tremor at 8Hz.

On Wednesday, I'll be 'debating' Sven Bestmann about sample size. Does 'Sky has any interesting (controversial?) views on this which are particularly relevant for the paradigms ans methods use for sensorimotor control research? Please RT

this is a cool one!

How predictable is neuroscience? Can LLMs outperform humans? Please participate in the BrainGPT.org survey to help us find out. You choose between two versions of a neuro abstract: the original vs. one with altered results. Which is which? research.sc/participant/... 1/2

Cool! so quick! thanks!

Hi, I just made a Feed to collect "Brain Stimulation" content - hope you find it useful (-> add "Brain Stimulation" in your txt) #neuroscience

When it comes to awesome diagrams in early biomechanics works, Borelli remains undefeated. (From De Motu Animalium, 1680)

There are some next-level diagrams in old scientific books and articles. This one from Movement (1895) by EJ Marey. Fig 101: Method of simultaneously recording the foot pressure on the ground and the changes in elevation of the body during a jump.

I heard he sketched it himself in MS Paint.
