Can you remember what you ate for lunch on March 8, 1999? What about what you were wearing on Oct. 29, 1985? A handful of people — only 33 confirmed to date — can remember such minutiae, recalling almost every moment of their lives after about age 10 in near-perfect detail. They have what scientists call a highly superior autobiographical memory, and now researchers have identified what makes their brains special.

Researchers at University of California, Irvine (UCI) studied 11 people with the condition and flagged distinct quirks in nine structures of their brains. Most of those differences, unsurprisingly, were in areas associated with autobiographical memory. The participants also had more robust white matter linking the middle and front parts of the brain compared with a group of control subjects.

Documenting these brain anomalies gives scientists a “descriptive, coherent story of what’s going on” in the minds of people with this unusual condition, UCI researcher Aurora LePort explained in a statement.
