Researchers discover how a brain circuit allows eating despite anxiety

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 helps to overcome anxiety to perform essential behaviors such as exploring, feeding, and limiting maladaptive hyperactivity.

New chip restores reading ability for macular degeneration patients

A tiny wireless chip implanted in the back of the eye and a pair of high-tech glasses have partially restored vision to people with an advanced form of age-related macular degeneration. In a clinical trial led by Stanford Medicine researchers and international collaborators, 27 out of 32 participants had regained the ability to read a year after receiving the device.

CogLinks model reveals how the brain adapts to changing rules

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 can go astray.

New 3D human brain tissue platform integrates all major brain cell types into a single culture

A new 3D human brain tissue platform developed by MIT researchers is the first to integrate all major brain cell types, including neurons, glial cells and the vasculature into a single culture.

How task engagement reshapes the brain’s auditory processing

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, auditory cortex, is filled with neural activity that is not sound driven – rather, this activity times the task, each neuron ticking at a different moment during task performance.
