We’re happy to share our new preprint:
Somatic inhibition evokes dendritic spikes and bursting in cortical neurons when paired with top-down dendritic inputs.
This finding reveals a novel computation with implications from single-cell dynamics to system-level activity.

Monitoring 10,000+ neurons in vivo? Easy.
Making sense of the data? That’s the real challenge.
Our latest review tackles preprocessing and analysis of large-scale two-photon imaging.

Cuando eres feliz se nota en tu cerebro y en tu forma de actuar
La felicidad es capaz de cambiar los recuerdos que se generan en tu cerebro y, con ello, repercutir en tu forma de ver la vida.

楽しい思い出は忘れにくい 理研が解明、睡眠で記憶強化 - 日本経済新聞
理化学研究所の村山正宜チームリーダーらは、楽しい思い出が記憶に残りやすい仕組みを解明した。感情を伴う体験は記憶に残りやすい性質があり、睡眠時に特定の神経回路を刺激して記憶を強化していた。精神疾患や依存症の予防や治療法の研究につながる可能性がある。「楽しい」や「怖い」などの体験は記憶に残り、長い時間が経過しても思い出すことができる。こうした体験は動物が生存や繁栄をする上で有利な情報を含むことが多

Positive emotions plus deep sleep equals longer-lasting perceptual memories
Researchers at the RIKEN Center for Brain Science (CBS) in Japan have uncovered how perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep. The study&...

We uncovered how a positive experience strengthens perceptual memory. During learning and NREM sleep, the amygdala and a cortical top-down circuit coordinate their activities, enhancing perceptual memory. A collaborative work with @jojolab.bsky.social et al., doi.org/10.1016/j.ne...
