Some people in this world such as The Big Bang Theory’s Sheldon Cooper possess a memory with such extreme precision that they can recall events in detail from years or even decades in the past. They refer to this amazing skill as an eidetic memory. It turns out that individuals with this ability actually have different brains than normal people. A new study by University of California (UC) Irvine scientists found that these special people had variations in nine separate structures within the brain, and more robust white matter linking the middle and front parts.
