Cephalopods, vision’s next frontier
For decades, scientists have been teased by the strange but inaccessible cephalopod visual system. Now, thanks to a technological breakthrough from a lab in Oregon, data are finally coming straight from the octopus brain.

Inhibitory cells work in concert to orchestrate neuronal activity in mouse brain
A cubic millimeter of brain tissue, meticulously sectioned, stained and scrutinized over the past seven years, reveals in stunning detail the role of inhibitory interneurons in brain structure and function.

Immune cell interlopers breach—and repair—brain barrier in mice
The choroid plexus, the protective network of blood vessels and epithelial cells that line the brain’s ventricles, recruits neutrophils and macrophages during inflammation, a new study shows.

Widely used calcium imaging protocol can lead to spurious results, new paper cautions
The technique, which measures calcium currents as a proxy for neuronal firing, sometimes reports unusual and potentially misleading waves of activity in the hippocampus.

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.

Astrocytes sense neuromodulators to orchestrate neuronal activity and shape behavior
Astrocytes serve as crucial mediators of neuromodulatory processes previously attributed to direct communication between neurons, four new studies show.
