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.

Null and Noteworthy: Neurons tracking sequences don’t fire in order
Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)
Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.
