Ever wondered how services like Spotify are so good at finding new music you’ll love? Turns out they’ve learned a lot from neuroscience!

I’m excited to share my first article for @PennNeuroKnow providing a soft introduction to neural networks!

[PennNeuroKnow @PennNeuroKnow]

Do you ever listen to Spotify and think "how does it know exactly what kind of music I like??" This week's post by new writer @Catrina_Hacker explains how! https://t.co/MH19PPWowJ

Exited to share our latest @TrendsNeuro opinion paper on —intensive— fMRI, with @Tknapen @cvnlab @elimerriam! We discuss ways to maximize both quantity and quality of your large-scale “deep” fMRI dataset, and create a community resource 🧠

I’m so excited to share that in the fall of 2025, I’ll be starting as a tenure-track Assistant Professor in Computational Neuroscience in @YorkUPsyc at @YorkUniversity in Toronto, Canada! 🤩

I’m looking forward to working with my amazing new colleagues and students!

It's difficult to make decisions both quickly & well at the same time, yet, brains have an effective way to make decisions that are reasonably accurate & reasonably fast. Learn more about this balance in this week's piece by @PennNGG student @jake_a_parker https://t.co/q9GRS60EeR

Check out this week's piece, where PNK Co-Editor and @PennNGG student @Catrina_Hacker describes a new study uncovering how your brain balances inflammation in your body, opening the door to new treatment options for diseases characterized by inflammation. https://t.co/bwo2KnqUfk

[cvnlab @cvnlab]

We wrote a perspective piece on the emergence of hardcore (i.e. intense) big datasets in neuroscience and how it effects the way we do science with @elimerriam, @Tknapen and @eline_kupers! Let us know what you think!

Neurons are not the only cell type in the brain. In diseases like Parkinson’s & Alzheimer’s where we see neuronal death, researchers ask: what role do the other cell types play? Learn more in this week's article by @PennNGG student @joulesriley_ #scicomm https://t.co/yKr8Y2WfNL
