Novel motion simulator reveals key role of airflow in rodent navigation
With the assistance of a novel motion simulator, researchers at Bar-Ilan University in Israel have discovered that rats rely on airflow to navigate their surroundings. When they move, the flow of air relative to their bodies provides crucial information, complementary to their sense of balance, to perceive their own motion in space. This might explain their agility in the dark as they scurry through pipes and tunnels, turn corners, and effortlessly travel from one location to another, all while knowing exactly where they’re headed.

Researchers Identify Potential Therapeutic Target for Management of Thirst Disorders
In a recent mouse-model study, published in Nature Neuroscience, researchers at University Hospitals (UH), Harrington Discovery Institute at UH, and Case Western Reserve University have now found that the cerebellum also controls thirst, a major function necessary for survival.

This leads to an enhanced drive to seek and drink water.
