L22 Memory 1

• Outline what the hippocampus is important for:


  Explicit/ declarative memory

  Spatial memory

  Relational memory

  Episodic memory
• What is the basal ganglia important for?

  Implicit memory/ non-declarative

  skill learning
• What happens in the Morris water experiment?

  The rat learns the layout of a maze, but if hippocampus is damaged it will only randomly search.

  Therefore, the hippocampus is important in spatial memory.
• What is the relational memory theory?


  The hippocampus does not represent space as such, but more the relationships among the overlapping cues in the environment.
• Episodic memory theory:


  The hippocampus is critical for episodic but not semantic memory.
• Working memory:


  Prefrontal and parietal cortex = executive/ attentional functions

  Association cortex = storage of specific material

  Temporal cortex = associated more with visual working memory and less with spatial

  Parietal lobe = spatial memory
