My pre-PhD work is out @CurrentBiology! We studied Alston’s singing mice, neotropical rodent that produces loud, human-audible 'songs' and engages in vocal turn-taking. Using thermal imaging in semi-natural arena, we probed song use across social contexts. cell.com/current-biolog…

📚AMB Katahira made his first visit to the #HideyoNoguchi Memorial Ceremony at Woodlawn Cemetery, marking the 150th anniversary of his birth. We honored Dr. Noguchi’s global legacy and congratulated the 9th Scholarship recipients carrying his torch of courage into the future.

Happy to share our new review on Neural Mechanisms of Social Hierarchy across Species. We discussed how different individuals in various species, from fish to humans, achieve high social status and the neural circuits supporting each of those strategies. nature.com/articles/s4158…

In a new study published in @Nature, CSHL graduate student Emily Isko in the @ArkaupBanerjee Lab discovered an evolutionary difference in Alston’s singing mice that allows for enhanced vocal capabilities. Read more: cshl.edu/what-can-singi… @TonyZador #InspiringDiscovery #ScienceMakesLifeBetter

Proud to see this work finally out and featured in Scientific American! It was such a joy working with Joergen Kornfeld's group to visualize the interactions of migrating neurons in the adult songbird brain, see the full paper here: sciencedirect.com/science/articl…

What has changed in mama bear brain (well, actually mice) to make her risk her life to attack a potential threat and protect her young? Oxytocin is the key! Happy to share our new study led by two awesome postdocs: Takashi Yamaguchi and Rongzhen Yan. nature.com/articles/s4158…

Super excited to give a talk in the main auditorium at COSYNE in Lisbon about my ongoing PhD work on how the hippocampus supports vocal interactions in singing mice! 🐭🎤♬🧠 📍 Auditorium I 🗓 Mar 13 (Fri) 9:30–9:45 #COSYNE2026

Mostly just a note for future me. yukifujishima.com/blog/2026/01/2…

Merry Christmas! 🎄🎤🐭🎵

My first paper @MPFNeuro is now out in Nature! Thanks everyone who has supported us behind the story!!

Come see our poster to learn how the hippocampus supports turn-taking vocal interaction in Central American singing mice! #Sfn2025 #SfN25

Thrilled to announce I'll be starting my own neuro-theory lab, as an Assistant Professor at @YaleNeuro @WuTsaiYale this Fall! My group will study offline learning in the sleeping brain: how neural activity self-organizes during sleep and the computations it performs. 🧵

@PegahKF @unibern @snsf_ch Would love to!

@PegahKF @unibern @snsf_ch congratulations!!

@kayautoka nycではおせわになりました！ ますますのご活躍を祈念してます！

SNSでの報告が11月になってしまったのですが、10月から東京科学大学に着任しました！ 精神行動医科学分野に所属し、脳外科の先生方とも協力しながら、アメリカ滞在中に取り組んでいた計算論的精神医学と頭蓋内神経活動記録の研究を発展させ、国際的な研究拠点を築けるように頑張ります！

How does life evolve to adapt to modern cities? Out now in @ScienceMagazine, my PhD work with @LindyMcBr uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation. 🧵(1/n) science.org/doi/10.1126/sc…

Diffusion models learn probability densities by estimating the score with a neural network trained to denoise. What kind of representation arises within these networks, and how does this relate to the learned density? @EeroSimoncelli @StephaneMallat and I explored this question.

The work with bats on barren, 7-acre Latham Island was Nachum Ulanovsky’s most complex undertaking yet. By @claulopezneuro thetransmitter.org/neuroethology/…

Just out! “The astrocytic ensemble acts as a multiday trace to stabilize memory.” We identified astrocytic ensembles that link experiences across days to stabilize memory nature.com/articles/s4158…. New astrocyte tools are openly available at Addgene: addgene.org/Jun_Nagai/. 1/8
