A dieter wrestling with cravings for fatty foods might be tempted to blame their tongue: the delicious taste of butter or ice cream is hard to resist

MIT scientists report that when they change the rules of a task, a pair of regions on the brain’s surface collaborate to update that understanding and change behavior to fit the new regime.

Scientists have found a cluster of rhythmic brain cells in newborn mice that may explain why spoken languages around the world share a common tempo.

Using what may be a fundamental circuit architecture in animal brains, worms decide whether to roam around looking for food or stop in a patch of nutrients. The circuit feeds multiple streams of sensory information into a mutually inhibiting loop of just a few neurons to switch between the roaming or dwelling behaviors.

Brain circuits or brain mechanisms that regulate threat/fear responses in animals have been discovered.
