The science Twitter-verse has been abuzz this week about a larval fruit fly connectome published 10 March in Science, the most complex complete connectome to date. It includes “all sensory inputs, all interneurons across both brain hemispheres, and all descending neurons,” tweeted Michael Winding of the University of Cambridge in a thread describing his team’s work. Spectrum covered the brain map when it was released.
What makes this connectome special? It’s the full picture: all sensory inputs, all interneurons across both brain hemispheres, and all descending neurons. This allows us to follow sensory information through the brain and investigate how it’s converted to behavioural instructions pic.twitter.com/Kh6eOpFf25

“I’m excited to see what else people do with this awesome dataset,” tweeted study investigator Ben Pedigo of Johns Hopkins University.
I’m excited to see what else people do with this awesome dataset – network is available in the paper supplement, and feel free to reach out with any questions or requests!

The “huge feat” of mapping the entire connectome will help neuroscientists better understand neurological diseases, tweeted Shyam Diwakar of the Amrita Mind Brain Center.
Mapping the entire #connectome of #Drosophila – a huge feat indeed! Furthering #neuroscientists to study how the #brain works and to better understand neurological #diseases. https://t.co/vWa56VkpaY

“Characterizing the connectome in higher animals will help us to understand the functioning of our brain,” tweeted Rebeca Osca of the Salk Institute.
Characterizing the connectome in higher animals will help us to understand the functioning of our brain. Congratulations to @WindingMichael et al on their latest work published in @ScienceMagazine. A great advancement for neuroscience! #NextSteps???????? https://t.co/oYrtIyAgVy

This resource will help “change the way we ask and answer questions in neuroscience and pave the way for larger mammalian connectomes,” tweeted Amy Robinson Sterling of Princeton University.
New connectome out in @ScienceMagazine, that of a baby fly. Congrats @WindingMichael @ZlaticLab @albertcardona @neuro_data et al. This resource + upcoming @FlyWireNews adult fly connectome will change the way we ask and answer questions in neuroscience and pave the way for… https://t.co/GApM6aqITh pic.twitter.com/OYPGHC4Oyy

Another connectome study, posted as a preprint to bioRxiv also on 10 March, earned its share of laudatory tweets. The resource has “structural and functional whole-brain networks” for about 40,000 people and features multiple measures to choose from, tweeted study investigator Andrew Zalesky of the University of Melbourne.

The project took 20 years’ worth of computing time to complete, and the connectomes are all available on the U.K. Biobank data-sharing platform. The resource could “enable new studies of the human connectome in health, disease and aging at an unprecedented scale,” according to the preprint.
“We provide the largest brain connectivity resource to date,” tweeted study investigator Sina Mansour L., also of the University of Melbourne. Mansour also shared a link to the code used to create the connectome, “including example scripts on how to use the resource.”
Overall, we provide the largest brain connectivity resource to date, with several functional time series (27 per session) and structural connectivity matrices (28 per session) totaling more than a million pre-computed alternative connectomes.

“What a massive endeavor providing not one but 28 out-of-the-box versions of structural and functional brain networks, including intermediate data and code,” tweeted Florian Ph.S Fischmeister of the Medical University of Vienna.

“This is an incredible effort, thank you for making these data available!” tweeted Leonardo Tozzi of Stanford University.
