Sorry to hear that. Hope everyone is ok

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.

New preprint alert! See thread below by @lehmannsj.bsky.social describing his heroic efforts where we test some important assumptions about cTBS. This was a beast of an experiment so we’re very interested in community feedback.

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

Parkinson’s Disease affects the contextual control, but not the expression, of a rapid visuomotor response that initiates visually-guided reaching: Evidence for multiple, interacting motor pathways an... Despite significant deficits in voluntary motor control, patients with Parkinson’s disease (PD) can generate reflexive or stimulus-driven movements. How are such spared capabilities realized? Here, we...

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...

New lab preprint on express visuomotor responses in PD, this time on the lower limb. This one shows that EVRs on the lower limb are also spared in PD, and are reciprocally regulated with ensuing anticipatory postural adjustments. Great job by first author Lucas Billen! doi.org/10.1101/2024...

New results from the lab – spared reflexive responses in PD. Think express saccades, but for arm muscles. Huge credit to co-first authors Madeline Gilchrist and Becca Kozak, and other collaborators. Straight line from our animal work to this, and more to come soon. www.biorxiv.org/content/10.1...
