Scientists have generated the first complete map of the brain of a small insect. The map shows all 3,016 neurons and 548,000 synapses tightly packed in a young fruit fly's brain, which is smaller than a poppy seed go.nature.com/3ZTAU8q
How does the brain work? š§
Today, scientists reveal the first complete brain wiring map in a relatively complex animal.
The map can help understand how signals travel through the brain to drive behaviour and learning š

ok. i've peaked. it's all downhill from here. i was interviewed as the "expert not involved in the study" by GIZMODO (!!š!!) on the new larval connectome paper, out today in science from @albertcardona, @ZlaticLab, and colleagues. amazing work!! gizmodo.com/first-complete-mā¦
We would like to cordially thank to @albertcardona, Carey Priebe, @jovo, Volker Hartenstein, Richard Fetter and their labs and @HHMIJanelia for all the support on this journey š
The complete synaptic-resolution connectome comprises 3016 neurons and 548,000 synapses. We believe that this complete brain connectome will be a lasting reference study, providing a basis for a multitude of theoretical and experimental studies of brain function in generalš§
I am starting my own research group at @TheCrick Institute in London! We will be investigating how neuronal circuits in the brain drive social interactions between animals.
I have an immediate opening for a PhD student, apply by 22 March!

š¢Did you know that we have developed a high throughput training system that allows real-time behaviour detection of freely moving larvae (up to 16) with targeted opto- and #thermogenetic stimulation of tracked animals in #Drosophila?

2/3 This stimulation is delivered automatically with high temporal precision and is controlled in either open- or closed-loop. Using this approach, we show for the first time that Drosophila larvae can perform classical #conditioning with no overlap between sensory stimuli.
3/3 In addition, our system will enable rapid screening for neurons and circuits that underpin different forms of learning and also has the potential to drive future research in larval taxis, decision-making, and spatial navigation and #memory.
Over 50,000 annotations have been added to the connectome by the FlyWire community!
This APL neuron, tagged by @mwpleijzier@zhihaozheng, is 20x longer than a fly's whole body and is the longest cell in the brain.

Sneak peek:
We will soon be releasing a complete insect brain connectome! With both brain hemispheres mapped, we can study how the left and right sides of the brain communicate #Drosophila#neuroscience
š Our new preprint is out on #BioRxiv
It is a comprehensive work between our lab, @albertcardona lab and our collaborators, with our talented postdoc @WindingMichael as a co-first author and also one of the coresponding authors š„³
Check out our new preprint: the complete #connectome of the entire #Drosophila larval brain, with all inputs and all outputs, and a comprehensive analysis of feedforward and feedback pathways across both brain hemispheres #Neurosciencebiorxiv.org/content/10.1101/ā¦

What a great week of a lot of exciting science at the first in-person @MRC_LMB symposium since 2019. Congratulations to our postdoc @AutomneNine on being awarded the Joan Steitz Prize! So well-deserved George.
@EPFL wrote a nice piece on our latest work developing tools to perform long-term / lifetime-scale recordings of ventral nerve cord motor circuits in behaving flies.
Led by @LauraHrmns and @DrMuratKaynak jointly between my and @mssakar 's laboratories:
