Anxiety is often described as a whole‑brain problem, but a series of mouse experiments suggests that, in some cases, a single misfiring circuit can tip the balance between calm and fear. By nudging ...

Endogenous lithium levels were lower in the prefrontal cortex of people with Alzheimer's and mild cognitive impairment. Lithium depletion in mouse models led to increased amyloid and accelerated ...

In a lab far from the woolly mammoth’s icy plains, researchers from Colossal Biosciences have successfully brought a tiny “woolly mouse” to life. Here’s what it could mean for de-extinction. A tiny, ...

Study in mice offers insights into the brain circuitry underlying certain types of reward-based choices. Researchers identified distinct groups of brain cells activated when animals anticipate a ...

Research in mice identifies brain circuitry that supports certain reward-based decisions. Every day, our brain makes thousands of decisions, big and small. Any of these decisions -- from the least ...
