Map of a billion brain links reveals clues about how we think

Scientists have created an elaborate map of more than a billion brain cell connections, helping to shed light on how memories are formed and recalled.

Scientists have created an elaborate map of more than a billion brain cell connections, helping to shed light on how memories are formed and recalled.

Their complex series of images are the first to illustrate how these vital connections are organised and could impact on our fundamental understanding of the brain.

Researchers also showed that this molecular map is altered in mice with features of autism and of schizophrenia, suggesting that it could provide vital insights on brain disorders.

The study focused on gaps between brain cells -- known as synapses -- that allow chemical and electrical messages to flow and are vital to healthy brain function.

This is the first time that such a map -- called a synaptome -- has been created across the entire brain.
