  1. 3 types of Memory categorized by time
    • 1. echoic, perceptual, sensory
    • 2. working, blackboard, short-term
    • 3. long-term
  2. explicit (declarative) memory
    • everyday usage
    • includes semantic, episodic
  3. implicit (non-declarative) memory
    • memory for skills, habits, and behavior
    • neuro-motor
    • cerebellar
  4. How is memory stored?
    neurochemical equation that are linked between a collection of cells
  5. What is a memory called?
    an engram

    aka a memory trace
  6. Where is short term memory housed?
    in the frontal lobes, temporal lobes and distributed throughout the brain
  7. Medial temporal lobe areas of particular importance are:
    • hippocampus
    • entorhinal cortex
    • perirhinal cortex
    • parahippocampal area
    • fornix
  8. Where are long term memories housed?
    in the diencephalon and distributed throughout the processing brain regions
  9. Diencephalon regions of particular importance:
    • anterior nucleus of the thalamus
    • dorsomedial nucleus of the thalamus
    • hypothalamus
  10. amnesia
    serious loss of memory and ability to learn
  11. Three types of amnesia
    • retrograde amnesia
    • anterograde amnesia
    • transient global amnesia
  12. retrograde amnesia
    memory loss for events that occurred before the trauma
  13. anterograde amnesia
    inability to form memories for event that occur after the trauma
  14. transient global amnesia
    a sudden occurrence of anterograde amnesia that is also often accompanied by retrograde amnesia for recent events

    occurs for a short time period during which the person is confused and often disoriented it is often the result of a transient ischemic attack (a vascular episode)
  15. relational memory
    concept of a memory process that links events and ideas together
  16. Where does relational memory take place?
    hippocampus (still under debate)
  17. procedural memory
    • non-declarative memory (implicit memory)
    • is involved in how we do things (the processes, the steps)
  18. Where is procedural memory stored?
    Mainly in cerebellum
  19. What is important in planning and executing procedural memory?
    striatum (basal ganglia region)
  20. What is the striatum composed of?
    the caudate nucleus and the putamen
  21. Where does perceptual memory occur?
    within the specific sense area of the brain
  22. Important area for working (short term memory):
    the pre-frontal lobe
  23. Important areas for declarative and non-declarative memories
    temporal lobes and specific diencephalon areas
