Grid cells create multiple local maps rather than single global system for spatial navigation, study finds
Grid cells are a class of specialized neurons in a brain region called the entorhinal cortex, which is known to support spatial navigation and some memory processes. Past neuroscience studies have found that as humans and ...

Eat, explore, rest: Leptin-sensing brain circuit helps overcome anxiety to meet vital needs
How do mammals manage to eat in situations that cause anxiety, step into exposed spaces, or slow down when anxiety drives them to keep moving? A new study pinpoints a leptin-sensitive circuit in the lateral hypothalamus that ...

Do animals fall for optical illusions? What fish and birds can teach us about perception
Have you ever looked at two circles of exactly the same size and sworn one was larger? If so, your eyes have been tricked by the Ebbinghaus illusion, a classic example of how context can shape what we see. Place a circle ...

How the auditory cortex syncs with behavior to help the brain become a better listener
When we are engaged in a task, our brain's auditory system changes how it works. One of the main auditory centers of the brain, the auditory cortex, is filled with neural activity that is not sound-driven—rather, this activity ...

Men experience more brain atrophy with age despite women's higher Alzheimer's risk
Women are far more likely than men to end up with Alzheimer's disease (AD). This may, at least partially, be due to women's longer average lifespans, but many scientists think there is probably more to the story. It would ...
Preventing overhydration: Study uncovers a neural circuit that prompts mice to stop drinking
Identifying the neural mechanisms that support the regulation of vital physiological processes, such as drinking, eating and sleeping, is a long-standing goal within the neuroscience research community. As the disruption ...
A 'flight simulator' for the brain reveals how we learn—and why minds sometimes go off course
Every day, your brain makes thousands of decisions under uncertainty. Most of the time, you guess right. When you don't, you learn. But when the brain's ability to judge context or assign meaning falters, thoughts and behavior ...
