Early in life, the protein Reelin helps assemble the brain. Later on, it appears to protect the organ from Alzheimer’s and other threats to memory and thinking.

A new generation of blood tests can help diagnose Alzheimer’s disease. But many doctors don’t yet know how to use them.

An experimental cancer drug that helps the brain turn glucose into energy was able to reverse memory loss in a mouse model of Alzheimer’s disease.

A virtual version of a fruit fly’s visual system could help scientists understand how brain networks process information. The model could also lead to more efficient AI systems.

For 22 years, Jason Mazzola’s life was defined by a genetic condition that can cause autism and intellectual disability. Then he started taking an experimental drug.

The first full map of an adult fruit fly’s brain shows 50 million connections between neurons. Researchers are using the map to learn how all brains work.

Green eggs and ham? Even toddlers know when an event appears to be impossible, not just improbable.

A study of cells from 84 brains finds that Alzheimer's has two distinct phases, and that one type of neuron is especially vulnerable.
