Are virtual flies playing Beat Saber? SM64? Doom? No. The new fly connectome is an incredible achievement! Less is going on in the sim videos than it seems. I'm stoked to see people engage with neuroscience though. My breakdown: www.neuroai.science/p/are-flies-...

Really wise (and delightful) *DO NOTs* for speaking. Among my favorites: "Design your talk so that <30% of the audience understands it". Even if your discoveries are very important, that's bad. Value = f(discovering stuff, explaining that stuff coherently). 🎯.

Do brain circuits really sit in a 'soup' of neuromodulators? Are neurons like soggy bits of bread soaked in signaling factors? Is the whole brain just squelching around in one big pool of warm modulators?

Nice - made this some time ago based on a Brain Emulation Roadmap Report: github.com/ihstevenson/... Interesting idea that, possibly unlike brain regions, all of the neuromodulators haven't even been discovered yet

Ursula K. Le Guin on the true pain of being a writer
Screenshot of a single question and answer from interview in the Times Literary Supplement with Ursula K. Le Guin. Here is the quote:

If you could make a change to anything you’ve written over the years, what would it be?

In The Dispossessed, I would mention the communal pickle barrels at street corners in the big towns, restocked by whoever in the community has made or kept more pickles than they need. I knew about the free pickles all along, but never could fit them into the book.

Yeah 300, I think our "simulation 2" would be easy enough to scale up to something like 3k simultaneously recorded spikes (or 3m serially recorded) to test your argument. The sparseness of spikes and timescale of synapses still makes me optimistic that you can at least get *some* real interactions

We have one model here for monosynaptic effects: doi.org/10.51628/001.... Sometimes the monosynaptic model doesn't work well, though. I haven't really dug into these cases, but suspect there's probably high-frequency common input and/or reciprocal connections

Ian Stevenson @ihstevenson.bsky.social · 11/01/2025
I've seen (somewhat rarely) these types of oscillatory ccgs on this timescale. Sometimes you can get these types of effects when the neurons are just bursty. You might check ACGs or CCGs on isolated spikes or try to deconvole similar to work from Eggermont in the 90s.

I think it's true we can't say much about the majority of synapses (because they are too weak or are between neurons with few spikes), but, occasionally, the causal effects are clear in the observational data

Ian Stevenson @ihstevenson.bsky.social · 19/09/2024
I think modeling synapses from spike observations alone is still scientifically interesting/useful even without verifying causality. Some arguments here - doi.org/10.51628/001... - including power analysis
