We describe Ca2+ waves though the hippocampus. Mesmerising but artefact of GECI expression.

In neuroscience, we often try to understand systems by analyzing their representations — using tools like regression or RSA. But are these analyses biased towards discovering a subset of what a system represents? If you're interested in this question, check out our new commentary! Thread:
![What do representations tell us about a system? Image of a mouse with a scope showing a vector of activity patterns, and a neural network with a vector of unit activity patterns
Common analyses of neural representations: Encoding models (relating activity to task features) drawing of an arrow from a trace saying [on_____on____] to a neuron and spike train. Comparing models via neural predictivity: comparing two neural networks by their R^2 to mouse brain activity. RSA: assessing brain-brain or model-brain correspondence using representational dissimilarity matrices](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:e6ewzleebkdi2y2bxhjxoknt/bafkreiav2io2ska33o4kizf57co5bboqyyfdpnozo2gxsicrfr5l7qzjcq@jpeg)

Hi Bluesky!
Happy to share my PhD work:
Spatial information was consistently represented across tasks in a low-dimensional subspace of PFC activity, while task identity was encoded in an orthogonal subspace, providing a stable and independent representation of context.

As someone who has spent the last 25 years studying sex differences in brain function and behavior and the last 10 advocating (loudly) for SABV and working to help my colleagues implement the policy into their work, this is utterly heartbreaking.
Great write up at @thetransmitter.bsky.social on the seeming erasure of SABV in the new era of NIH. Gotta say The Transmitter is killing it the last few weeks, first to report on the Federal Register block and now this. Leading the charge! 💪 www.thetransmitter.org/policy/exclu...
Exclusive: NIH appears to archive policy requiring female animals in studies
Such a shift would “put us back in the dark ages in terms of our science,” says neuroscientist Anne Murphy, who helped to formulate the original policy.

Scientists are now organizing events, called Stand Up for Science, on 7 March in Washington, D.C., and state capitals.
So far, they have attracted more than 100 volunteers from some 30 states who are hoping to rally support for research as a public good. scim.ag/4328LAD
