Memory formation involves complex interactions at the cellular level within the brain. This research focuses on how specific neurons in the hippocampusā€”the region associated with memory and learningā€”respond to information by forming memory circuits. Notably, these neurons endure molecular changes and damage to their DNA during the process. The study reveals that after neurons encounter learning stimuli, they display sustained DNA damage, which activates a molecular pathway involving TLR9, a protein that assists in DNA repair and cellular response to damage.
