The hippocampal map has its own attentional control signal!
Our new study reveals that theta #sweeps can be instantly biased towards behaviourally relevant locations. See 📹 in post 4/6 and preprint here 👉

🧵(1/6)
Attention-like regulation of theta sweeps in the brain's spatial navigation circuit
Spatial attention supports navigation by prioritizing information from selected locations. A candidate neural mechanism is provided by theta-paced sweeps in grid- and place-cell population activity, which sample nearby space in a left-right-alternating pattern coordinated by parasubicular direction signals. During exploration, this alternation promotes uniform spatial coverage, but whether sweeps can be flexibly tuned to locations of particular interest remains unclear. Using large-scale Neuropixels recordings in freely-behaving rats, we show that sweeps and direction signals are rapidly and dynamically modulated: they track moving targets during pursuit, precede orienting responses during immobility, and reverse during backward locomotion — without prior spatial learning. Similar modulation occurs during REM sleep. Canonical head-direction signals remain head-aligned. These findings identify sweeps as a flexible, attention-like mechanism for selectively sampling allocentric cognitive maps. ### Competing Interest Statement The authors have declared no competing interest.

We don't even understand how psilocybin works in complex neuronal networks, yet we've known about it for decades.

This is something clearly different. Does it work via the same mechanisms of psilocybin? It is a variant of psilocybin? A new compound entirely? Does it work via serotonergic action?

I made a quirky little web app to help guide your lucid dreams: context-lab.com/dream-stream/

It's kind of like a "netflix" or "spotify" for lucid dreaming-- you select different narratives to form a playlist, and then it uses your device's microphone to start playing when it detects you're in REM.

🧠 Why it matters 🧠
-The results challenge a prevailing view that 5‑HT2A activation alone drives psilocybin’s therapeutic actions.
-Highlights the importance of polypharmacology 🥳, and points to the 1B receptor as a target for non‑hallucinogenic antidepressant and anxiolytic pharmacotherapies.
New paper drop! 🧠💊 Our new paper out in Molecular Psychiatry shows that the serotonin 1B receptor is important for the neural and antidepressant/anxiolytic behavioral responses to psilocybin in mice.

Is there any evidence for anti-Hebbian plasticity during sleep? This is an old hypothesis that continues to get cited (and to appear in some computational models), yet I haven't been able to find any study that shows this. There's ample evidence of synaptic downscaling, but that's different.
