New preprint from our lab ⚡ Why do DA and BF bursting neurons carry such similar reward-prediction signals? Are they independent, driven by common input, or causally linked? We find a direct answer: DA activity rapidly and causally drives BF. www.biorxiv.org/content/10.6... 1/10

Dopamine neurons drive basal forebrain reward prediction in milliseconds
Phasic reward prediction signals in ventral tegmental area (VTA) dopamine (DA) neurons and basal forebrain (BF) noncholinergic bursting neurons are remarkably similar despite the distinct circuit…

If you ever wondered why visible light is those particular wavelengths, it's because life evolved to see in the narrow range where water is transparent

Is this a hollow bar chart, some kind of a clever compromise for those who want and those who don't want summary bars? From @schreinerdrew.bsky.social in Nature: www.nature.com/articles/s41... Excellent data sharing makes for a quick remake try using just lines at the means. #dataviz
Chart from https://www.nature.com/articles/s41586-026-10510-x, with 3 categorical values on the x axis. Each category has some dots and what look like an unfilled bar chart (just the bar edges).Remake of previous chart with the hollow bars replaced the horizontal lines when the tops of the bars were. And different jitter.
