Veronica's model pictures mood on a washboard (빨래판) potential and proposes how the brain’s clock may stabilize mood. The circadian clock rhythmically tilts it and sustains daily “ups and blues” while helping keep mood from sliding into deep depression. doi.org/10.1063/5.0327423

Prof. Masayuki Ikeda's visit to the Braintime Lab.

The Chronotype Paradox: intrinsic circadian periods are slightly left-skewed, yet human chronotypes are heavily right-skewed. We show stochasticity in sleep pressure accumulation is sufficient to flip the skew. biorxiv.org/content/10.64898…

Circadian swings in the mood potential protect against falling into mood extremes such as mania and depression, and this helps explain why bipolar disorder and circadian dysfunction subtly interact. Work by Veronica Will (now at UCSD). biorxiv.org/content/10.64898…

We know use of affective words show circadian fluctuations. Now Vuong and Mariana show circadian structure in embedding space, too: morning peak in local semantic exploration, later peak in global diversity as posts accumulate. arxiv.org/abs/2601.15091

Circadian biologists from Korea, Japan, and Taiwan got together at #KSBNS2025 — Jihwan Myung, Eun Young Kim, Kazuhiro Yagita, and ShihKuo Chen!

Braintime Lab’s Vuong and Sun Lab’s Mariana took a joyful moment to celebrate their upcoming marriage💍 with a one-of-a-kind photo shoot! #BraintimeLab #SunLab #LoveInTheLab #CircadianRhythms #BuryingBeetles #ScienceAndStory

Our super-postdoc Hélène is back from GRS/GRC after her wonderful talk and poster presentation! We still need to absorb what she learned there—but we are so proud of her. #GRC2025 #HeleneVitet

Our amazing master's student Veronica has officially graduated! Huge congratulations from all of us at Braintime Lab!

Circadian clocks in the body likely 'entrain' themselves rather than hierarchically reset. Given internal cellular feedback, omics (Bharath @TimelyScientist) may accurately predict their phases via connectomics, something single-gene reporters cannot. doi.org/10.1016/j.sleep.2025…
