Is the Brain Born 'Blank' or 'Full'? New Study Reveals a Surprise

A mouse study in Nature Communications tracked a hippocampal memory circuit from birth to adulthood.

Researchers found the circuit begins with dense, largely random connections that are later pruned into a more organized network.

The study challenges the idea that the brain starts as a blank slate.

Early dense wiring may help young brains learn and integrate information more efficiently.
