An Open-Source Restraint System for Magnetic Resonance Imaging in Awake Rats Magnetic resonance imaging (MRI) is a critical tool for translational neuroscience, but preclinical studies frequently rely on anesthesia, which alters neural activity and limits comparison with human...

Excited to share this in final form @sfnjournals.bsky.social: An Open-Source Restraint System for Magnetic Resonance Imaging in Awake Rats www.eneuro.org/content/13/2... if anyone wants to try doing it, give us a call! Happy to help you get going!

The strongest version of this illusion I’ve seen! Absolute head-wrecker!

Forward vs Inverse problems: why high performance machine learning usually means little about how the world works Understanding causality from machine learning is unfortunately usually impossible; life sciences take note

Well-predicting machine learning in no way means that you can understand how the world works.

being super kind to yourself and others either through a sense of humour or honesty is wisdom enough. rest, relax, rejuvenate!

New paper led by wonder postdocs Francesca Greenstreet and @jessegeerts.bsky.social and @clopathlab.bsky.social trying to understand why –in the "what for" sense– there are multiple motor learning systems –supervised and RL-based– in the brain.

The belly of the beast is an important place. That is how you bring it down. You just proved it with your responses.

**How distributed is the brain-wide network that is recruited
for cognition?**
That goes to the top of the list!

Yes, its a different world altogether

We can still do our work but let it be about the work and less about us? when we allow the self importance and big personality go, our work benefits.
