Area of Science:

  • Neuroscience
  • Cellular Biology

Context:

  • Neuronal plasticity underpins information storage in the brain.
  • Plastic events involve alterations in synaptic function, structure, and number.
  • These events are hypothesized to relate to learning and memory processes.

Purpose:

  • To review studies reporting experience- and learning-dependent structural brain changes.
  • To highlight the role of the hippocampus in spatial learning and memory.
  • To explore the link between new synapse formation and long-term memory.

Summary:

  • Structural changes in the hippocampus are observed following spatial learning.
  • The formation of new synapses after learning is associated with long-term memory consolidation.
  • NMDA-type glutamate receptors are essential for learning and synaptogenesis.
