Release September 4th, 2023
New Neuron Widget
Public datasets contain now a new Neuron widget (replacing the Segment widget) with an improved table user interface with global search, per-column filtering, reordering of columns etc. Individual entries can be copied to the clipboard on click (useful e.g. for segment ID column).
ColorMIP Atlas for FANC
More than 18k colorMIP images of FANC neurons are now downloadable (only with community access) from the About widget.

Cell Type Atlas
First version of a cell type atlas with underlying data model. Individual proofread neurons in specific datasets have to be mapped to commonly agreed cell type identifiers in a specific species according to a particular author or publication. This cell type atlas uses this data model to represent all this information to map reconstructed public neurons from EM datasets to cell types in different species, starting with fruit flies. The interfaces provides an entry point to filter cell types in a species, and potentially also brain region, and lists all the unique identifiers for cells in any of the datasets available on the platform. These identifiers can be used as entry points to retrieve the neurons, and further study their morphology, connectivity or other annotations available.
It is important to note that each definition of a cell type identifier, or each statement that a particular neuron in a specific dataset is an instance of a cell type, has to be supported by an author or publication. Thus it is possible to have mutually exclusive or overlapping cell typing nomenclatures or schemes for any given datasets. We do not attempt to curate and merge such different nomenclature. We do assume that the same cell type identifiers (exact spelling) in different nomenclatures corresponds to the same criteria used to define the cell type.
CAVE Table Widget
A new CAVE table widget allows for datasets that are backed by the CAVE infrastructure to retrieve a list of all tables with their description. Individual tables can be opened and their records are retrieved in a table. For annotations with an associated spatial location, a button allows to navigate to the 3d location in Neuroglancer. Records can be filtered and selected, and their corresponding segment IDs copied for futher usage in other widgets.
The new Feed section of the website collects recent publications in the field of connectomics, covering all stages of the data generation pipeline as well as applications to address biological circuit questions, and review and methods publications. The entries do not need to contain a link to a peer-reviewed publication, but can also link to tweets, or any other web resources. The hashtags help with finding useful entries and may later be used for filtering. One goal is to highlight how neurons and circuits mapped based on electron microscopy have been useful to uncover principles of neural computation.
The feed is generated from a user of the decentralized social network Nostr. Specifically, from user account. If you like to contribute to this feed, please get in touch. You can simply setup an anonymous user account on Nostr.rocks and share the public key with us. If the feed is appropriate and relevant, we are happy to include it here.
Tools and Resources
A new interface for the Tools and Resources section allows to do full-text search across record titles, descriptions and tags. Each record can also be filtered by its corresponding tags. This allows to quickly find and explore resources that may be relevant for a particular stage in the connectomics pipeline.
