Scientists from the Albert Einstein College of Medicine of Yeshiva University in New York made a short video that shows how the brain cells make memories.
The team marked particles in the brain called messenger RNA (mRNA) molecules with fluorescent tags.
These molecules code for a substance called beta-actin protein, a key player in making memories.
By stimulating neurons in the hippocampus (the part of the brain where memory is formed), the researchers made the creation and storage of memory visible.
