Webinar | From Neuronal Morphologies to Insights using the OBI Virtual Labs
Published June 3, 2026
In this webinar, we introduce the morphology-related functionalities of the Open Brain Institute Virtual Labs and show how they bring these workflows together in one integrated environment.
Through hands-on use cases, we will demonstrate how the platform supports efficient dataset exploration, interactive visualization and inspection of reconstructions, collaborative data sharing, automated detection and correction of reconstruction artifacts, and morphometric and topological analyses — including how topological approaches can reveal meaningful morphological differences across species.

Our new paper in PLOS Computational Biology
Published June 2, 2026
Excited to share our new paper in PLOS Computational Biology.
"A multimodal spatial atlas of transcriptomic, morphological, and electrophysiological cell type densities in the mouse brain”
For the first time, we've built a unified, high-resolution 3D atlas of the mouse brain that speaks all three languages of neuroscience — gene expression, cell shape, and electrical activity — at once.
Using MERFISH spatial transcriptomics data, the Allen Brain Cell Atlas, and patch-sequencing datasets, we mapped 5,274 transcriptomic cell types across the entire mouse brain at 25 µm³ voxel resolution. We then developed a probabilistic framework to translate these into 458 functional morpho-electrophysiological types — bridging the gap between modern transcriptomics and decades of classical cell-counting literature.
Understanding the brain isn't just about knowing which genes cells express — it's about knowing where they are, what shape they take, and how they fire. This atlas brings all three together in one place, opening new doors for large-scale brain simulation, disease modeling, and circuit-level neuroscience.The atlas and all tools are fully open-access. Whether you're building computational models, analyzing spatial transcriptomics, or exploring inhibitory neuron gradients, this resource is built for you.

Webinar | Spines & Motif Participation
Published April 2, 2026
The second webinar of our series is open for registration!
Most cortical excitatory connections are made onto dendritic spines.
But beyond plasticity, could spines actually enable which connections are formed?
Using our Virtual Labs and EM data from the #MICrONS project (Allen Brain Institute), we will explore whether dendritic spine anatomy is linked to the topology of local brain networks.

Leveraging and Accelerating Simulations Neuroscience.
Multi-scale biophysically-detailed brain models are a powerful scientific tool, acting as general models for exploring a wide range of scientific questions. The talk introduces these models and proven applications, from understanding spike sorting biases to predicting structure-function relationships. Openly available electron-microscopic datasets enable the next generation of one-to-one tissue models. Lessons learned from previous collaborative efforts are characterized to leverage existing models and accelerate new model development. The Virtual Labs of the Open Brain Institute, an open platform for collaborative neuroscience, simplify international teams’ efforts to leverage existing models and build one-to-one brain models.
