I’m happy to share that our paper about the Sepia officinalis genome is out in eLife!🧬 We compared the assemblies of two individuals that had a different predicted number of chromosomes, and found highly repetitive regions that likely prevented a complete assembly. elifesciences.org/articles/107...

Some fly neurons are “dimorphic”, existing in both males and females but connecting to different neighboring neurons. Neighbors may be “isomorphic”, the same in both male and female; or sex specific; or dimorphic themselves. Here's an example, the type AOTU012, present in left and right instances.

We provide the most detailed picture yet of the result of sexually dimorphic development of the nervous system. The dataset should be a game-changer for researchers exploring behaviour, circuits & brain wiring! Check out male-cns.janelia.org. Huge thanks to our amazing team of co-authors! 10/10

Statistical analysis of connectivity within the central brain shows that around 6.5% of synaptic connections in the male and 1.3% of connections in the female are dimorphic. In the male, sex-specific circuit elements form highly interconnected clusters with similar connectivity. 9/10

Using these annotations we ran end-to-end analyses going from sensory inputs all the way to motor outputs. This showed, for instance, that ascending and descending neurons are not passive relays but likely perform complex transformations of information flowing between brain and nerve cord. 4/10

Using 2P photo-activations and a ML classifier, we assigned functional labels to neurons based solely on morphology, enhancing our EM dataset. Our classifier also provides a basis to assign functional labels to other cell library resources for which calcium imaging had not been performed. (8/10)

We performed 2P calcium imaging to identify functional cell types related to this integration process. We then performed EM on the same preparation and mapped the two datasets together with cellular precision. Zetta AI has been instrumental in processing and segmenting the EM dataset. (6/10)
