∂DSA finds lots of RNN solutions to the same integration task: Line attractors ✅ Feedforward chains ✅ Oscillations ✅ Unstable dynamics ✅

DSAmaxxing for comparing dynamical systems! Some really great work from @neurostrow.bsky.social on advancing DSA to be able to shed light on complex, noisy neural dynamics AND using DSA as a regularizer to discover novel RNN solutions Really lucky to have been included and involved in this!

Masa's paper is out in Hippocampus. The left-right alternation of hippocampal theta sequences at T-maze choice points, much loved as a 'planning' signal, falls straight out of MEC dynamics. Well done @masahironakano.bsky.social, fun project with @clopathlab.bsky.social doi.org/10.1002/hipo.70131

This is wild. >1/2 of HC synapses disappear in artificial hibernation, come back in same/similar locations & memories intact. ~1/2 of engram synapses-between two memory-tagged cells-are clustered on dendrites, those preferentially spared. Not biggest synapses. 1/ www.science.org/doi/10.1126/...
