New dopamine sensor powers three-color imaging in live animals
The tool leverages a previously unused segment of the color spectrum to track the neurotransmitter and can be used with two additional sensors to monitor other neurochemicals at different wavelengths.

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.

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.

Astrocyte networks span large swaths of brain
The networks are plastic, connect brain regions that aren’t connected by neurons and may enable long-distance communication between astrocytes, a new preprint shows.
