Wait… localized norepinephrine transients in the awake visual cortex?! Who would have guessed this neuromodulatory signal is that spatially precise, right where visual processing is happening. Brain state control just got a lot more local. @ruedigersarah.bsky.social www.nature.com/articles/s41...

Check out our latest research drop! We show BLA dopamine signaling encodes the emotional weight of sensory transitions, but not the associative strength or value of stimuli. These signals dynamically rescale when the learning context changes: "this matters most!" www.biorxiv.org/content/10.1...

Hung-tu Chen, Nicolas Tritsch, Matt van der Meer, and I have submitted a new preprint (doi.org/10.1101/2025...) in which we use simultaneous hippocampal ephys and ventral striatal (VS) fiber photometry to establish a link between sharp-wave ripples (SWRs) and VS dopamine (DA) in mice. (1/9)

Ventral Striatal Dopamine Increases following Hippocampal Sharp-Wave Ripples
Leading theories suggest that hippocampal replay drives offline learning through coupling with an internal teaching signal such as ventral striatal dopamine (DA); however, the relationship between hip...

Miriam Janssen: 1% of your tax dollar goes to science
APPROXIMATELY 1% of your tax dollars are used to fund science research. The Trump administration is cutting roughly 40 to 50% percent of this research funding — what does that

We are looking for a research assistant/lab manager to join the lab! A supportive, collaborative environment where you can learn neural recording with Neuropixels, optogenetics, fiber photometry, and neural data analysis.
