Simons Collaboration on the Global Brain news site. Long-term recordings of large populations of neurons reveal neural motifs representing internal states.

September 14th, 2022

International Autoimmune Encephalitis Society blog. Many types of autoimmune encephalitis can result in movement disorders. In this post I break down some of the most common movement disorders and how they help distinguish subtypes of autoimmune encephalitis.

Penn NeuroKnow. How our brain signals when rewards differ from what we expect.

April 12, 2022

Penn NeuroKnow. Why the relationship between brain size and intelligence is so complicated.

Penn NeuroKnow. Recent developments in our understanding of how COVID-19 affects the brain have led scientists to revisit an old idea that Alzheimer's could be virally induced.

November 23, 2021

Penn NeuroKnow. Restoring sight to the blind sounds like science fiction, but a recent study puts us one step closer to making this fantasy a reality.

Penn NeuroKnow. What is happening differently in our brains when conversations click versus when they don't?

May 25, 2021

Penn NeuroKnow. To learn about how we recognize faces, neuroscientists study the most and least skilled face recognizers.

March 23, 2021

Penn NeuroKnow. How do we decide when to try something new and when to stick with what we know?

January 26, 2021

Penn NeuroKnow. Big companies like Google and Spotify use what we know about the brain to build a class of models called neural networks that help power many of their services.
