Memory and Learning

• Memory and Learning: Changes to synapse underlie learning and memory
• NS Development: made when a fetus; regulated by genes and singals; brain remodeled after birth
• Neural Plasticky

  • response to activity (like remodeling)
  • more synapses cause change in structures of connections in neurons
  • 1st level: remodeling via competitions allows for growth (competing to be more important ex. if you think important the more you think about it)
  • Synapse elimination: keeps only required (winners)
  • 2nd level: strength of synapse (become more strong or weak depending on how much you think about them
• STM:

  • held for short time
  • accessed by temporary link in hippocampus
  • acquire memories but not maintain
  • 5-7 at a time
• LTM:

  • info stored in cerebral cortex
  • permanent
  • infinite
  • matter of retrieving
