Summary

  • Neuroscientist Todd Sacktor has devoted his career to understanding how memories persist in the brain.
  • In the 1990s, he discovered a protein called PKMζ that accumulates in the brain’s synapses - the connections between neurons - during the creation of a memory.
  • Yet, decades later, the exact role of this molecule in the memory process remained unclear.
  • In a paper published in Science Advances in 2024, Sacktor and his colleagues found that the protein interacts with another called KIBRA.
  • The pair work together to strengthen memories over time.
  • When the interaction was disrupted in mice, their ability to form new long-term memories was inhibited.
  • The discovery offers a molecular explanation of how memories can endure a lifetime despite the body’s fleeting molecules.
