Forming long-term memories requires many types of neurons and brain regions working together. Yet the full set of molecules behind memory is still unknown.

What they work on

  1. Map the brain-wide gene activity changes needed for long-term memory in C. elegans, combining behavioral training with spatial transcriptomics and profiling of cell-body and synaptic compartments.
  2. Test which identified genes are required for memory formation, using temporally and spatially precise gene manipulation in specific neurons.
  3. Use unbiased behavioral profiling to find patterns of variation in memory performance and predict which individual worms will keep better memory with age.
  4. Identify core memory components that set individual memory performance, using epigenomic and genomic methods, and confirm their role in age-related memory loss.

More about the research

It is also unclear why some individuals remember better than others, a difference that grows with age. This project uses the tiny roundworm C. elegans, whose every neuron and connection is already mapped and which uses the same memory molecules as humans. The goal is to define memory at the molecular level across the whole nervous system and over the lifespan.

Why it matters

Memory fails in age-related cognitive decline, Alzheimer's disease and neurodevelopmental disorders. Identifying the molecules needed to form memories, and those that keep memory strong with age, could reveal pathways disrupted in these conditions. These could become targets for therapies that preserve or improve memory.
