‘Understudied secret’ in brain dampens nicotine drive in mice

The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Newly found circuit through visual cortex powers first look at faces

The superior colliculus, an evolutionarily ancient brain area responsible for eye movements, responds to faces before the canonical face areas do, a study of macaque monkeys suggests.

Why neural foundation models work, and what they might—and might not—teach us about the brain

These models can partly generalize across species, brain regions and tasks, suggesting that a set of machine-learnable rules govern neural population activity. But will we be able to understand them?

Embrace complexity to improve the translatability of basic neuroscience

Researchers must learn to view heterogeneity as an essential feature of the systems they study and a central consideration in experimental design, not a variable to control for or reduce.
