Rapid, biochemical tagging of cellular activity history in vivo

Intracellular calcium (Ca2+) is ubiquitous to cell signaling across all biology. While existing fluorescent sensors and reporters can detect activated cells with elevated Ca2+ levels, these approac...

New paper online! In 2018, we found a human brain signal that tracks real time fluctuations in mood/anxiety. Now Adam Jackson back-translates this biomarker to mice, dissects its circuit mechanisms, & tests its causal relationship to emotional state. 🧵1/6 authors.elsevier.com/sd/arti…

New tools from my lab. Due to Minju Jeong's extensive efforts to validate the tools and Jun-Hyeok Choi's ingenious molecular design, we can now present additional methods to identify and modulate specific neuronal populations. cell.com/neuron/fulltext/S08…

Viral vector-mediated transgene delivery with novel recombinase systems for targeting neuronal...

Jeong et al. created a new viral technique, ΦC31/pSIO vector, to target specific neuronal cell types without cross-reactivity with Cre and Flp recombinases. These easy-to-use viral tools for robust...

Neural signatures of stress susceptibility and resilience in the amygdala-hippocampal network

The neural dynamics that underlie divergent anhedonic responses to stress remain unclear. Here, we identified neuronal dynamics in an amygdala-hippocampal circuit that distinguish stress resilience...

Neurogliaform cells dynamically decouple neuronal synchrony between brain areas

Input selection in brain neuronal networks involves a local inhibitory cell that can decouple neuronal synchrony selectively and temporarily.

Awesome work by @yongseoklee7 and @SangJeongKim1. The Cerebellum plays a role in fear memory.
Yong-Seok Lee@yongseoklee723 Mar 2023
Excited to share our new paper published in @CellReports. We show that the cerebellum modulates fear memory via its projection to the parabrachial nucleus. Thanks and congrats to my colleagues, especially Kyoung-Doo (tweeterless) and @SangJeongKim1! cell.com/cell-reports/fullte…

Very happy to announce the publication of my first first-author paper in @CellReports! We find that ramping and phasic dopamine neuron activity reflect reward prediction error, improving goal-directed navigation. Thread (1/8) 👇 cell.com/cell-reports/fullte…

Midbrain dopamine neurons signal phasic and ramping reward prediction error during goal-directed...

Dopamine neurons signal reward prediction error in their phasic activity, but reports of ramping activity and its potential function remain controversial. Using experimental and computational...

Our preprint examining hippocampal dynamics during learning is up biorxiv.org/content/10.1101/… Interested in learning? Information processing by neural ensembles? Division of function across subnetworks? The hippocampus? Come along for a quick look at some highlights… 1/n

Population dynamics underlying associative learning in the dorsal and ventral hippocampus

Animals associate cues with outcomes and continually update these associations as new information is presented. The hippocampus is crucial for this, yet how neurons track changes in cue-outcome...
