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!

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.
SpinePhiladelphia@SPINEPhilly13 Sep 2023
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)

Do flies make "voluntary" decisions to engage in "play like behavior"? This study watches flies over hours/days in a chamber with a rotating carousel! (1/2) biorxiv.org/content/10.1101/…

Seeking voluntary passive movement in flies is play-like behavior

Play-like behaviour (PLB) is pervasive across the animal kingdom, especially in vertebrate species. Invertebrate PLB has been restricted to social or object interaction. Here we examined individual...

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)

1/2 Las moscas pueden pasar minutos tomando una decisión Han estudiado la ovoposición de las moscas de la fruta, el mecanismo que les permite evaluar opciones (rise-to-threshold), y como sus decisiones se benefician del tiempo que toman (paper) nature.com/articles/s41586-0…

By studying the brains of fruit flies, a team led by NYSCF – Robertson #Neuroscience Investigator Alumnus Gaby Maimon discovered a neuronal mechanism involved in minutes-long decision processes, which could help explain how animals make educated decisions: go.nature.com/3Y6JroD

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)

What's next? With this signal at hand we can start to understand the molecular and circuit mechanisms behind various factors that are integrated to control the exact timing and outcome of decisions (spontaneity, working memories, value calculations, body needs, etc.). (10/11)

I'd like to thank all my coauthors -- Gaby, @BarryJDickson, @FeiWang06517334, Kaiyu, @ChakraArun, @adachi_at, and @theHessam ! And @RockefellerUniv @HHMINEWS ! Stay tuned for more on this and other signals/principles that control the moment of decisions & actions! (11/11)
