Memories lost due to diseases like Alzheimer’s may be able to be restored.

  • The new study provides evidence contradicting the idea that long-term memory is stored at synapses.
  • Using pulses of Serotonin, a hormone that promotes synapse formation, researchers attempted to rebuild identical versions of destroyed synapses.
  • Instead new synapses were created entirely, disproving the old theory that memories are located in synapses. Researchers think memories may be in the neurons instead.
