Researchers in Japan demonstrated that exposing certain brain pathways to blue light can weaken or eliminate a learned motor memory.
Blue Laser Shrinks Neural Connections to Erase Memories
Activating the blue laser causes the memory “branches” to shrink, effectively erasing acquired skills, with these effects occurring in roughly 10–20% of nearby neurons.
Scientists believe this technique could target hundreds of thousands of microscopic neural connections, allowing a single memory to be erased without disturbing others.
Targeting Memories with Blue Light for Precise Erasure
By using blue light to shrink the exact brain connections where memories are stored, it suggests a future where harmful or traumatic memories could be removed with remarkable precision.
