• University of Queensland researchers have identified two types of stem cells in the hippocampus, a region of the brain crucial for learning and memory.
  • Previously, these neurons were all thought to be identical, so it wasn’t understood how the region is able to regulate behaviours as divergent as learning and mood. The existence of distinct stem cell populations suggests that they give rise to different types of neurons, which explains the varied functions of the hippocampus.
  • The discovery may have implications for the treatment of learning- and mood-related disorders.
