Today, we had a great #iBehave lecture by Yaniv Ziv at the #DZNE. He presented his work on #RepresentationalDrift in the #hippocampus and entorhinal #cortex, studying #PopulationDynamics of freely moving mice Great insights into how neuronal codes evolve across time!

#neuroscience #CompNeuro

New study by Johnston, Kirschhock & Nieder (Nature Comm., 2025): Carrion #crows estimate time intervals using abstract magnitude coding in the nidopallium caudolaterale (avian “prefrontal” #cortex). NCL neurons tuned to 1.5 s, 3 s & 6 s wait times predicted intended duration, independent of cues. This demonstrates that sophisticated timing is possible – even without a #neocortex.

“Correlation ≠ causation”? This new study put it to the test: activity in posterior parietal #cortex not only correlates with navigation choices, it is causal. Using a #BrainMachineInterface, mice could steer solely from these signals.

New preprint by Ruff, Markman, Kim & Cohen (2025): #NeuralPopulation formatting matters for function. In monkeys combining motion and reward, both middle temporal area (#MT) & dorsolateral prefrontal #cortex (#dlPFC) encode both signals. But MT formats them separately, dlPFC integrates them. A recurrent #RNN model predicted, and microstimulation confirmed, distinct #behavioral impacts.

I listened to the latest #cortex this week, state of the workflow with Simone Giertz. I don't know if Simone is on here, if she is someone pelase tag her. I've been having great fun today with #DiceTasking. I'm gonna call it dicetasking. IYKYK

A great episode

In our recent #JournalClub, I presented Genkin et al. (2025), who decode #DecisionMaking in the #PremotorCortex of #macaques as low-dimensional #latent #dynamics shared across #NeuralPopulations. Their generative model links tuning curves, spike-time variability, and stimulus-dependent potential landscapes to a common internal decision variable. I summarized and discussed their findings in this blog post:

Zhou & Schapiro show in their recent study that a gradient of complementary #learning systems can emerge through #metalearning. Their model self-organizes into subsystems that differ in timescale and representational abstraction – offering a mechanistic account of distributed #memory architectures across #cortex.

New in #eLife: #CellSeg3D introduces #WNet3D, a self-supervised 3D #segmentation method for #microscopy data — no labels needed. Claims to outperform #Cellpose/#StarDist on 4 datasets. Includes #opensource plugin (#Napari) + full 3D annotated #cortex dataset. Will test it later.

Just published – “The dynamics and geometry of choice in the premotor #cortex” by Genkin et  al. shows how the #brain encodes #decisions. Using single-trial #NeuralRecordings, they model #decisionmaking as 1D trajectories on a high-dimensional #manifold.

Key findings:
Diverse tuning curves reflect one latent decision variable
Dynamics follow an attractor
Geometry links sensory & cognitive coding

You'll probably get an error if you want to run a #Java 21 (or newer) application on a #RaspberryPi 3, Zero 2, or other type with an #Arm #Cortex #A53 processor. It's a known bug already fixed for the July update release. Until then, you can still run your app with extra command-line options as a workaround.

All info is available in a blog post on our site:

I've been complaining about this map for months, but now that it's done, I can share with you the rather impressive (if I do say so myself) timelapse of the illustration process. I'm really rather proud of how this one came out!

(the video's too big for anyplace but YouTube)

(Reshares vastly appreciated, btw!)

The personal story of this man telling about his polio, also a neurological disorder, and how he fought against it with surgery and transplanting mussles all over his body is both very moving as impressie.
