I wanted to test the torsional VOR in my newborns, but couldn’t get ethical approval from my wife 😂

Sorry to hear it Ravi. Please pass on our condolences to Anne.

These pubs are the product of collabs with Penny MacDonald (Western; upper limb) and Vivian Weerdesteyn (Radboud; lower limb), and influenced by lots of work with Tim Carroll and Sam Contemori (U Queensland) and Jerry Loeb (USC). Straight line as well from our animal work. Basic research FTW!

Sparing of EVRs on the upper and lower limb in PD, despite deficits in other aspects of motor control, tells us something the selective pathophysiology of this disease on descending motor circuits. The ability to regulate this circuit may also be compromised in PD.

We suggest that express visuomotor responses represent a privileged period of muscle recruitment influenced by rapid processing of visual signals through the superior colliculus, for initiating fast-as-possible reponses on the arm for visually-guided reaching, or leg for visually-guided stepping

This work follows on work we posted on late last week on express visuomotor responses on upper limb muscles (I know, during US Thanksgiving). Think express saccades, but now for arm muscles. Congrats to co-first authors Madeline Gilchrist and Becca Kozak. See doi.org/10.1101/2024...
