A fruit fly walking on an agarose laiden treadmill deciding where to lay her eggs! She clearly prefers laying eggs on the green option. Her body is held with a pin to keep her in place allowing for brain activity measurements as well as quantitative behavioral analysis.

Just finished day one at my first Brain Computer Interface conference/symposium. Certainly want to make it a habit to attend more events outside of my academic research areas in the future! #NYBCI24

Vote! Lots of good candidates to pick from. Eric has been a great collaborator and mentor, and I'm sure he would make a great GSA Fly Board President!

A nice @CurrentBiology dispatch about our recent work. Helps link our work to the broader neuroscience and Drosophila communities! cell.com/current-biology/ful…

Can't wait to share my work with the NYU neuroscience community and meet some amazing scientists!
🧠✨We’re busy planning exciting things here at the NI - many of which will drop in your feeds starting now ⤵️⤵️⤵️ Excited to present this impressive lineup of the 2023-2024 NYU SPiNES speakers! #Neuroscience #NYUSPiNES med.nyu.edu/departments-inst…

Excited to have an opportunity to meet more of the Philly neuroscience community and some amazing postdoc colleagues! If anyone wants to meet, let me know! I'll be around on the 26th and 27th.
SPINE'23 is 2 weeks away- registration for our meeting (and poster session!!!) is still open! Head over to spinephilly.org to be a part of our all day event. We've got 8 amazing postdoc talks lined up, a poster session, and many opportunities for philly neuro networking.

It's rare to link individual modifications on RNA to phenotypes. Nice work by @TheDrSparkles and @RNAwilinski tying a small subset of RNA methylation sites -> insulin translation -> biological/metabolic phenotypes. (1/2) nature.com/articles/s41594-0…

Would be interesting to see if these methylation sites could be dynamically controlled by the internal/external environment. I'm intrigued by the possibility that we (fly researchers) may eventually be able to tie dynamic methylation -> neuronal physiology -> behavior. (2/2)

I really appreciate studies that watch flies and try to extrapolate. There are "caveats" and alternative explanations here... But that may be inevitable when addressing complex questions. Has me thinking of experiments and analysis that may more be more conclusive 🤔. (2/2)

A fly's internal organs unraveled. This perspective reminds me that there is more to a fly than a brain (brain = tiny white structure all the way to the left). (single fly, gray = dapi, cyan = phalloidin)

Nice to see our work tweeted in Spanish!

Love seeing the differences in egg-laying behavior in different insects!
Check out the crazy ovipositor of this mama root-boring longhorn beetle (Cerambycidae: Prionus). The larvae feed on roots and can damage trees, hence the name. The male hanging on to her is quite a bit smaller. Woodstock, NY.

A nice summary of one of the aspects of our work in @Nature by @RockefellerUniv! Click to learn more about a rise-to-threshold process that can guide minute timescale decisions in #drosophila.
Researchers in the #MaimonLab identified a brain signal in fruit flies that guides one type of decision-making—findings that could build a foundation for understanding how humans make educated and strategic decisions. #RockefellerScience rockefeller.edu/news/34303-r…

It's out! Curious to know what happened in your brain to make you stop and read this tweet 🤔? We found a rise-to-threshold process in specific fly brain neurons for a "similar" type of decision! @Nature nature.com/articles/s41586-0… (🧵1/11)

Flies run around and sample substrate options for seconds to minutes prior to depositing each egg. But what controls the exact moment a fly stops searching and commits to an option? [10x speed] (2/11)

Scientists that have joined Mastodon: Are there still interactions with non scientists? This is one of the reasons I joined Twitter, and I'm curious if these interactions exist in Mastodon.

Want to know how single cells in the fly brain control when and where individual eggs are deposited? Come by my poster #SfN22 Sunday 1-5pm TT2 to learn more (or to say hi!). (video: orange dot = opto stim -> egg, right panel = single cell imaging, 20x speed)

Upshot: protect your produce by keeping a rotten banana nearby 🪰😅😂
A new buzz in the housing market: Flies weigh their recently visited surfaces or “real estate” options to decide on the best one for laying their eggs. scim.ag/mk

IMO the @eLife papers from #VosshallLab are just as good as the CNS ones. Read them (before complaining)!
#VosshallLab @RockefellerUniv @HHMINEWS will continue to publish our best work in @eLife as we always have: bioRxiv 2022.03.01.482582 (in revision) PMID: 35550041 (2022) PMID: 33284111 (2020) PMID: 31112133 (2019) PMID: 26670734 (2015)

Paper is out! #Drosophila 'know' what's best! Flies build an internal expectation of the substrate options in their environment and use it to make informed egg-laying decisions. science.org/doi/10.1126/scia… [fly exploring options before laying an egg on the best one, 20x speed]🧵(1/7)

(2/7) I started my postdoc in search of an interesting deliberation process in an animal with a tractable brain #Drosophila... And it turned out that flies choose where to lay eggs much like how we choose a restaurant in a new city!

Getting back in the groove after Ascona Neural Circuits and a 🇨🇭 vacation. Perhaps the most encouraging takeaway was seeing that many 🪰 neuroscientists were invited!

In those wasted 10 minutes you could have browsed the Drosophila connectome and figured our how the fly 🧠 works!
Getting a lot of questions, but this was a necessary and proportionate response to the fact that I spent 10 minutes talking to someone at SfN last year only to find out they were a postdoc in a Drosophila lab.
