- Wow I want to do this (to be fair I'm trying to anyway 😁)
- Reposted by Anirudh WodeyarI came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

In this paper (just published) I try to formalize how living systems are non-equilibrium, information-processing, adaptive matter.

- Your stomach called – your striatum picked up! But does this actually happen in humans? Using simultaneous dopamine PET/fMRI, we show that the gut hormone ghrelin helps the brain adjust motivation to current metabolic need. Here’s what we found👇 Preprint: shorturl.at/pq4A3 #neuroskyence #🩺
- Well, this is awesome: academic.oup.com/brain/advanc...
- Fascinating and ground breaking work. I don't think we've ever looked at sinle neuron activity in the human thalamus before.
- Thalamus for vision BCIs Scientists have recorded single neurons in the human LGN for the first time, revealing how it links the retina to visual cortex. When one eye is closed, neurons tuned to that eye reduce their activity, while neurons tuned to the open eye increase in spikerate #neuroskyence

- These are all important and relevant points as well. As are others made in these and other threads about oscillations. But one line of thinking I find missing is that of seeing it all as a singular dynamical system. Spiking networks produce activity that organizes in oscillatory bursts. (1/3)
- Immediately a fan from reading the behavioral experiment included here to study the effect of psilocybin
- Our new paper is out in Nature Communications! nature.com/articles/s41... We combined psychophysics, 7T fMRI, and computational modeling of vision with placebo, 5mg, and 10mg psilocybin, in the same group of participants, to clarify the computational mechanisms of psychedelics. 🧵

- Reposted by Anirudh Wodeyar1. The philosophy of science sometimes gets an unearned reputation as a purely academic exercise that offers little by way of concrete tools for advancing research. This is wrong. And today, as we grapple with how AI is changing the nature of scientific activity, it's desperately wrong.
- My favorite kind of science: www.science.org/content/arti... I feel I've observed this (dragonflies dipping into water then doing loop-de-loops) in the wild but never fully reflected on the why. The science involved and the experiments required to expose it are delicious to understand :)
- I hope (and suspect) that we will see more of this style of reasoning into the future in several areas. Essentially, you can more effectively enable brain state changes _from_ specific brain states. The idea has existed in other forms elsewhere - tracking phase of oscillations is a variation ...
- Reposted by Anirudh WodeyarHere's a bit of spice. Brain research clearly needs to tackle more complexity (than, say, Step 1: simple linear causal chains). But that leaves an ~infinite set of alternatives. Here, @pessoabrain.bsky.social advocates not for just a step 2, but a 3. /1 arxiv.org/abs/2411.03621

- This observation of reduced slow oscillation-spindle coupling may be explained by the mechanism that we proposed in a paper last year that when slow oscillations are coupled with epileptic spikes that reach the thalamus, spindle occurrence is reduced (see Figure 2D): academic.oup.com/brain/articl...
- Quite enjoyed passing through this new review: www.nature.com/articles/s41... on the interaction between epilepsy and sleep. Earlier work from @laurentsheybani.bsky.social et al. on local wake slow oscillations were cool observations that I could finally go through: www.nature.com/articles/s41...
- All odds ratios on this scale should ideally come with an icon array of expected frequencies under exposure vs without.
- Oof this style of reporting is exhausting. Read thread!

- The observation from Hu et. al. that sleep spindles seem negatively linked to discharges in Lennox-Gastaut (onlinelibrary.wiley.com/doi/10.1111/...) fits with our past work on epilepsy patients where epileptic spikes were disrupting sleep spindles (dx.doi.org/10.1093/brai...).
- Starting to wonder if the gains of auditory stimulation at night are reserved for folks who already have impairment of some kind. Everything I've seen so far would fit that expectation. www.medrxiv.org/content/10.1...
- The story of auditory stimulation to induce seeming slow oscillations in sleep gets ever more complicated: www.biorxiv.org/content/10.1...
- The difficulty of separating sharp wave ripples and epileptic spikes in human hippocampal recordings is all too real. This new paper seems to bring a new scope of data to bear on the problem - anatomic localization: www.biorxiv.org/content/10.1...

- The idea that slow oscillations tamp down neural activity overall is a bit of dogma in sleep neuroscience at this point. Feels like this work may help me understand what's under the hood behind that statement a little bit more...
- More human neurophysiology out today from the Geiger Lab. *Analogue* neuronal output modifies synapses for consolidation during sleep states. With such beautiful data and interpretation it’s easy to forget that the recordings are heroically tough. Fantastic research from @fxmittermaier.bsky.social
- This looks really cool!
- Is neuroscience research really working to understand the human brain? Or do we get lost in mouse cognition? I’ve asked myself this a lot since starting to work with human tissue.
