Brain wave stimulation may improve Alzheimer's symptoms

By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown that they can improve cognitive and memory impairments similar to those seen in Alzheimer's patients.

Brain wiring linked to age, sex and cognition

The degree to which the brain's wiring aligns with its patterns of activity can vary with sex and age, and may be genetic, suggests a study published by Weill Cornell Medicine investigators. The study finds that this alignment ...

How the brain paints the beauty of a landscape

How does a view of nature gain its gloss of beauty? We know that the sight of beautiful landscapes engages the brain's reward systems. But how does the brain transform visual signals into esthetic ones? Why do we perceive ...

A brain mechanism that automatically links objects in our minds

When people see a toothbrush, a car, a tree—any individual object—their brain automatically associates it with other things it naturally occurs with, allowing humans to build context for their surroundings and set expectations ...

The key role of astrocytes in cognitive development

Astrocytes have long been considered as mere support cells for neurons. In recent years, the study of astrocytes has grown, gradually revealing their importance in brain function. Researchers from Inserm, CNRS and Collège ...
