Of mice and human interneurons: Q&A with Moritz Helmstaedter
People’s brains have a larger network of inhibitory interneurons than mouse brains do, according to a new study. Changes to that network could contribute to autism or other conditions, says lead investigator Moritz Helmstaedter.

Everything everywhere all at once: Decision-making signals engage entire brain
The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.
