Oligodendrocyte precursor cells ingest axons in the mouse neocortex

…, R Lu, T Macrina, S Mu, S Popovych… - Proceedings of the …, 2022 - National Acad Sciences
Neurons in the developing brain undergo extensive structural refinement as nascent circuits
adopt their mature form. This physical transformation of neurons is facilitated by the …

[PDF][PDF] Reconstruction of neocortex: Organelles, compartments, cells, circuits, and activity

…, J Zung, A Zlateski, I Tartavull, S Yu, S Popovych… - Cell, 2022 - cell.com
We assembled a semi-automated reconstruction of L2/3 mouse primary visual cortex from ∼250
× 140 × 90 μm 3 of electron microscopic images, including pyramidal and non-…

FlyWire: online community for whole-brain connectomics

…, N Kemnitz, K Lee, R Lu, J Wu, S Popovych… - Nature …, 2022 - nature.com
Due to advances in automated image acquisition and analysis, whole-brain connectomes
with 100,000 or more neurons are on the horizon. Proofreading of whole-brain automated …

Functional connectomics spanning multiple areas of mouse visual cortex

…, S Papadopoulos, S Patel, X Pitkow, S Popovych… - BioRxiv, 2021 - biorxiv.org
To understand the brain we must relate neurons’ functional responses to the circuit architecture
that shapes them. Here, we present a large functional connectomics dataset with dense …

Structure and function of axo-axonic inhibition

…, D Ih, J Zung, A Zlateski, I Tartavull, S Popovych… - Elife, 2021 - elifesciences.org
Inhibitory neurons in mammalian cortex exhibit diverse physiological, morphological,
molecular, and connectivity signatures. While considerable work has measured the average …

[HTML][HTML] Neuronal wiring diagram of an adult brain

…, JA Bae, S Mu, B Nehoran, E Mitchell, S Popovych… - bioRxiv, 2023 - ncbi.nlm.nih.gov
Connections between neurons can be mapped by acquiring and analyzing electron microscopic
(EM) brain images. In recent years, this approach has been applied to chunks of brains …

Binary and analog variation of synapses between cortical pyramidal neurons

…, J Zung, A Zlateski, I Tartavull, SC Yu, S Popovych… - Elife, 2022 - elifesciences.org
Synapses between excitatory neurons in the cortex and hippocampus are typically made onto
spines, tiny thorn-like protrusions from dendrites (Yuste, 2010). In the 2000s, long-term in …

[HTML][HTML] Cell-type-specific inhibitory circuitry from a connectomic census of mouse visual cortex

…, S Papadopoulos, S Patel, X Pitkow, S Popovych… - bioRxiv, 2023 - ncbi.nlm.nih.gov
Mammalian cortex features a large diversity of neuronal cell types, each with characteristic
anatomical, molecular and functional properties. Synaptic connectivity rules powerfully shape …

Multiscale and multimodal reconstruction of cortical structure and function

…, J Zung, A Zlateski, I Tartavull, S Yu, S Popovych… - Biorxiv, 2020 - biorxiv.org
We present a semi-automated reconstruction of L2/3 mouse primary visual cortex from 3
million cubic microns of electron microscopic images, including pyramidal and inhibitory …

Chandelier cell anatomy and function reveal a variably distributed but common signal

…, D Ih, J Zung, A Zlateski, I Tartavull, S Popovych… - BioRxiv, 2020 - biorxiv.org
The activity and connectivity of inhibitory cells has a profound impact on the operation of
neuronal networks. While the average connectivity of many inhibitory cell types has been …
