Thrilled to share my final PhD paper @MosheParnas, now published in @ScienceAdvances! 🎉 Check out the incredible (but sadly rejected) cover art proposal—no iconic @Ella_Maru selfie this time, though. 😉 #Science #PhDLife #PhDone
1/ How do animals integrate different forms of learning? Our @Eyal_Roz new study in @ScienceAdvances shows that active mechanisms prevent the co-formation of competing memories. Here’s what we found! 🧵👇 science.org/doi/10.1126/sc… Art by @Ella_Maru

6/ Implications for Cognitive Science: Our findings challenge the hierarchical model of learning. Instead of additive memory formation, active processes separate these memories, allowing distinct behavioral strategies.
5/ Neuronal Circuit Insights: Operant learning requires the fly's navigation center (CX). CX activity gates plasticity, allowing operant learning while preventing interference from classical learning pathways. This active gating mechanism is key to resolving conflicting memories.
4/ Behavioral Differences: Flies show distinct behaviors after different types of conditioning. While classical learning leads to freezing, operant learning prompts active avoidance. This mirrors findings in mammalian studies suggesting shared cognitive principles across species.
3/ 🧑🔬 Surprising Discovery: Contrary to the dogma, we show that operant and classical learning cannot happen at the same time. If both forms of plasticity occur simultaneously, they interfere, leading to no effective learning. 🤯
2/ Classical vs. Operant Learning: Classical conditioning is passive, where an association is formed between a cue and an outcome. Operant conditioning is active, requiring the animal's action to influence the outcome. These different strategies involve separate brain circuits.

🔥🔥🔥How do operant and classical learning operate without interference? Discover the beautiful work by Eyal Rozenfeld and Shiko Parnas @MosheParnas, who addressed this question with sophistication and elegance. Congratulations! science.org/doi/10.1126/sc…
this is a long shot, but does anyone have a video of a faculty chalk talk they would be willing to share with me? neuroscience or bioscience preferred, but I'll take what I can get :)
New from Shiko Parnas' lab: Classical & operant learning in *Drosophila* rely on distinct neuronal pathways, challenging current paradigms! @MosheParnas Unstoppable science.org/doi/10.1126/sc…

I'm thrilled to share this story! Flies tend to aggregate, as I’m sure you have experienced in your kitchen. They lay eggs around the same places and form clusters even in the absence of food. But, what happens when they meet other flies for the first time? ...
Super excited to share that my thesis work is out @Nature today. How does brain control visceral organs through brain-to-body sympathetic signals? 👇 nature.com/articles/s4158… Best Thanksgiving gift! Very grateful for my amazing advisor, colleagues and collaborators.
Being raised alone makes flies afraid of one another! But exposure to other flies makes them become sociable. @VLobatoRios found and recorded specific learning circuits in the brain that regulate this transition. Read more in our new preprint: biorxiv.org/content/10.110…
With thanksgiving and face-stuffing season right around the corner 🍗🥧🍠 we present a deep dive into eating behaviors @AnnualReviews - across flies and mammals! w/ Nilay Yapici, Wenshuai Jiang and @namanagrawal97 Enjoy! annualreviews.org/content/journa…
