Hey #Neuroskyence, what are your thoughts on Research Resource IDs (RRIDs) for institutions/instruments? Some of our products are registered (PROPixx: SCR_013299), so have other tools ( @psychtoolbox.bsky.social is SCR_002881). Still lots of gaps, though... Do you use RRIDs? Thoughts?

We used @vpixx.bsky.social's PROPixx for high-speed video projection to reproduce the lawful saccadic conjunction of speed/duration/amplitude in a moving stimulus, and assessed observers’ ability to see the stimulus’ motion by asking them if the stimulus moved with an up- vs downwards curvature. 7/n

www.biorxiv.org/content/10.1... Between-movie variability severely limits generalizability of "naturalistic" neuroimaging. Not sure about the (over)generalization to all of naturalistic neuroimaging, nor the claim that this severely limits the approach. But definitely provides food for thought.
