    Does the concept of cortical columns extend to higher-level primate cortex? Using #DeepLearning & physiology, we found that V4 neurons cluster in columns & form functional groups biorxiv.org/content/10.110… Led by @KonstantinWille @kelli_restivo w/ @sinzlab @kfrankelab @alxecker 🧵

    Functional connectomics to mechanistically dissect cortical algorithms. We align 2P calcium with EM data using CNMF framework to recover cell body and dendritic activity in EM volume. Thanks @IARPAnews for funding biorxiv.org/content/10.110…

    After 7 years, thrilled to finally share our #MICrONS functional connectomics results! We recorded activity from ~75K neurons in visual cortex in a single mouse, then mapped its wiring using electron microscopy. To systematically characterize neuron function, we built the first

    Think government ROI is low? In the ‘60s, #NIH-funded researchers Hubel & Wiesel studied how cats’ neurons process visual info—seemed trivial, right? Yet their work led to convolutional neural networks like Hinton’s AlexNet, sparking the AI revolution that’s reshaping the global

    The ROI for most government expenditures is very low.

    1/4 Excited to share our latest work on feedback (FB). nature.com/articles/s4146…. There are abundant FB connections between cortical areas. To understand its function and its circuit level mechanisms we need to discover the FB cell type writing rules.

    Canonical circuits are thought to makeup the #cortex. But what is canonical about them? Lead by @FedericoScala7 and Dmitry Kobak we show that not all cell types are present across areas and propose that specific circuit motifs are used as building blocks disq.us/t/3i8a85j

    1/2 As suggested by our huge Patch-seq effort lead by @FedericoScala7 and @hippopedoid published today in @nature the tree of cortical cell types seems more like a banana tree with a few large leaves, rather than an olive tree with many small ones disq.us/t/3sufdoi

    Finding optimal stimuli for neurons has long been central for understanding information processing in the brain. This is hard because the search space is high-dimensional and sensory information processing is fundamentally nonlinear.Check out our preprint disq.us/t/39zixxq
