Is there anything more exciting than a new facility ready for research?

Last week, we were thrilled to sponsor the Brain Quantum Imaging conference and tour the new OPM-MEG @ Charité Berlin. Sensors from FieldLine, MSR from IMEDCO, and VPixx peripherals

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

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.

“Naturalistic imaging” paradigms, where participants watch movies during fMRI, have gained popularity over the past two decades. Many movie-watching studies measure inter-subject correlation (ISC), wh...
