In 'Southampton Water,' (1872) Whistler has reduced shipping vessels to ghostly forms in the deepening twilight, the only brightness comes from the reflections of lights and the moon. The setting serves primarily as a vehicle for his interest in the tonal harmonies of darkness.

"..CA3 operates as a nonlinearly gated scene constructor and CA1 as a continuous landmark integrator to build and maintain the cognitive map."

How visual scenes recruit spatial maps: threshold-gated activation in CA3 versus continuous integration in CA1

The hippocampal cognitive map is constructed from environmental sensory inputs, but the conditions that recruit a spatial map from a quiescent baseline remain unclear. Using a parametric virtual reali...

I’ve been standing stock still in this wood for about 10 minutes while I mess about with a photo on my phone. I look up, notice the shape, and slowly crouch down to film This has made me so happy I feel I could cry. It’s as close to magic as I hope to get.

The UK countryside is full of interdimensional portals. You just have to know where to look. I've decided to make a thread here of some of the best ones I've found on walks. 1. JRR Tolkien's Psychedelic Lime Kiln.

I can never resist getting inside an old lime kiln. This one was near Newton Abbott. The view up through the hole in the top of it to the overhanging trees on the ledge above is, I have to assume, even better than listening to the second Doors album on acid.

🧠 New preprint alert! 🧠 Leo led the heroic effort to improve how we map connections across large cortical networks in macaques—stably—over weeks to years. The secret sauce: a combo of optogenetics + µECoG + new signal processing to localize stim-driven responses. www.biorxiv.org/content/10.6...

Combining phase analysis and causal stimulation enables longitudinal mesoscale connectivity mapping

Uncovering the circuit mechanisms of flexible behavior requires characterizing how neural signals propagate across large-scale networks and tracking how those networks evolve over time. Signal propaga...

Thanks for sharing @hugospiers.bsky.social! This paper grew out of a collaboration between Arne Ekstrom's and Robert Wilson's groups. I'm especially grateful to Arne for providing access to this unique dataset collected by Ahbi, and to Bob for developing the control theory model.
