Oh yeah. In the lab, we’ve discussed every common definition because we study gap crossing jumps and the propulsive phase is likely the closest. I believe in frogs it is truly ballistic but mammals can tune it a bit

Yep, I’ve actually discussed it with him and stick by my argument that this would work great for some types of motor control but there are clearly ancient/core movements that this doesn’t explain well

Totally agree. As you know, I favor thinking of motor control principles varying depending on behavior and animal.

Actually, to take inspiration from Mark Latash, his translation of Bernstein’s book is one of my favorite descriptions of how this could all work together

Yep ;)

Omg, multi-particular muscles are so interesting

Doesn’t his model requires lots of feedback? Could be all different varieties

But this is very different, no? Doesn’t he propose that the final limb location/configuration is the control parameter? This may be true for some movements (eg visually guided forelimb) but I doubt it is right for others (eg ballistic hindlimb)

So I think of the low-d part as a control bottleneck point?

For example, we can elicit a multi-joint flexion synergy by stimulating some spinal neurons and that works regardless of limb starting position

Ah, I understand. But I think the stimulation studies that evoke synergies are a better case here than the ones that observe movements or EMG and do dimensionality reduction.

Can you expand on this one too, Andrew? Curious about your thoughts on it

Congrats, Jeff! I can’t wait to try it out

Yes I hope so! And thanks :)

Do you know of a third color that can be added to cyan and orange and for which the paired with overlaps are different? Thank you!

Agreed! But do any of these work for 3 color overlap analysis on a black background? For example, in RGB, we’d want to distinguish between R+G yellow vs R+B purple. But make it colorblind friendly
