Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

What are recurrent networks doing in the brain?
The cortex is filled with excitatory local synapses, but we know little about their role in brain function. New experimental tools, along with ideas from artificial intelligence, are poised to change that.

Newfound gene network controls long-range connections between emotional, cognitive brain areas
The finding could help unravel gene regulatory networks and explain how genetic and environmental factors interact in neurodevelopmental conditions.

As circuits wire up, interneurons take cues from surrounding cells
The inhibitory cells’ development, diversity and abundance in the cortex is directed in part by pyramidal cells, a new preprint suggests.

Opioid receptors may guide formation of gut nervous system in zebrafish
Fish lacking functional copies of the receptors have fewer enteric neurons than usual, but the findings await further validation.
