🚨Pre-print alert🚨 We stimulated serotonin while doing large-scale Neuropixel recordings across the mouse brain. We found widespread modulation of neural activity, but no effect on the choices of the mouse🐭 How is this possible? Strap in! (1/9) 👇🧵 doi.org/10.1101/2025.0…

After living in Germany for a year, this article made me laugh out loud. The director of my research institute here once told me that in a slow year, he physically signs ~1200 documents. cbc.ca/radio/sunday/e…

@KordingLab @shansiddiqi My thinking on causal inference is really influenced by Andrew Gelman's writing. In short, if we see that X and Y are correlated and the only plausible reason is that X causes Y, then we can infer causality. This is typical of randomized experiments, but not exclusive to them.

@shansiddiqi yes. I should have made clearer that the overall logic does sometimes allow a correlational finding to have causal meaning. Just most of the times it does not.

Last time I spoke about why correlation is not causation. Here I talk about why causation can often pragmatically be obtained. @kording/why-causal-knowledge-is-pragmatically-possible-bridging-philosophical-skepticism-and-scientific-490dbd63b8e8" target="_blank" rel="nofollow noopener">medium.com/@kording/why-c…

At JHU, our team will work on the circuit / algorithmic basis of intelligence & cognition, with attention to their malfunction in disease. We are looking for new team members with experience in circuit neuroscience, biology, or machine intelligence. Please DM if u are interested.

@OhUrbanity I've never felt so conflicted about the man. He's clearly bursting with pride for the auto industry... Maybe if he channels that energy into this trade spat he'll forget about bike lanes for a while.

I despise Doug Ford’s policies (on housing/transportation) but at least he gives the impression of actually caring about his country and wanting to stand up to American bullying and aggression.

President Trump is at it again. His 25 per cent tariffs on cars and light trucks will do nothing more than increase costs for hard-working American families. U.S. markets are already on the decline as the president causes more chaos and uncertainty. He’s putting American jobs at risk. I’ve spoken with Prime Minister Carney. We agree Canada needs to stand firm, strong and united. I fully support the federal government preparing retaliatory tariffs to show that we’ll never back down.

Already read the pre-print? doi.org/10.1101/2023.0… Come hear about our new re-analysis of a free reward consumption experiment from the Minmin Luo lab, and how heterogeneous discounting might fit in! 2/2

What makes serotonin neurons tick? Stop by #COSYNE2025 poster 1-116 on Thursday to hear about how an energy-efficient code for value explains the in vivo responses of serotonin neurons to rewards and punishments. 1/2

Apropos of never ending discussions about whether ANNs are "good" models of the nervous system, here is a slide I present to masters students showing a network that is found in motor control circuits *across phyla* (that's pretty ubiquitous!) I ask them to guess what it does...

If you want to do a postdoc w me (or generally do theory at Allen/UW) apply for this!   It’s a pretty independent postdoc position for people with a quantitative background, and pays well (104K)!    Due date is Dec 16th. Here’s the link to apply. tinyurl.com/coolgoodjob

New blog post about asymmetric learning rates in reward learning. What do they do and why? Slower learning for negative RPEs causes slower learning when the environment gets worse (duh!) but also causes an optimism bias when rewards are random. 🤔 efharkin.com/blog/2024-07-a…

Don’t remember which Buzsáki lab postdoc taught me this, but it was one of the best data analysis lessons from my PhD: Don’t bother learning statistical tests, because their assumptions are always wrong in the brain. Learn how to make fake data from your null hypothesis.
Allen Downey@AllenDowney

On Reddit's statistics forum, the most common question is "What test should I use?" My answer, from 2011, is "There is only one test" allendowney.blogspot.com/2011/05/there-…
