A snapshot of the summary - Cognitive Neuroscience of Memory

  • 1 Turning experiences into memory

  • 1.1 What is memory?

  • How do we get to know what is memory?
    By figuring out how and why it evolved
  • 1.2 Why did memory evolve?

  • Why did memory evolve?
    To predict the future.
  • Is memory generalized or specific? Why?
    Generalized and specific. Specific for differentiating between small differences, for example poisonous berries. Generalized for recognizing more of the same kind, all wolves for example.
  • 1.3 Nomenclature of memory

  • Which two processes are known for memory?
    Formation and retrieval.
  • Which two kinds of memory are known?
    Declarative and non-declarative
  • 1.3.1 Declarative memory system

  • Declarative memory can be characterized in four ways, name them:
    1. It is flexible
    2. It is consciously accessible
    3. It is able to compare events
    4. It is memory as a relational association (vs. Unconscious biasing as happens with non-declarative memory)
  • 1.5.1 Novelty

  • Which brain area is important for processing of novelty?
    Substantia nigra
  • Why is the substantia nigra important for novelty processing?
    Because it is where dopamine is produced, and dopamine rewards the investigation of novel items, enhancing memory.
  • Tracking memory formation

  • What is difference due to memory?
    It is when some studied items will be remembered and some forgotten in correlation with respectively higher and lower waveforms.
  • What is the difference between high and low-frequency words with regard to processing?
    High frequency words are semantically processed in the rhinal cortex. Low frequency words are non-semantically processed in the HC.
