LEARNING & MEMORY - Coggle Diagram

- - - - anterograde amnesia
        
        loss of ability to form new memory after brain damage
      - retrograde amnesia
        
        loss of memory events prior to brain damage occurence
    - - normal working memory
      - difficulty forming new declarative (explicit) memory
      - some degree of retrograde amnesia
      - better implicit memory than explicit
      - nearly intact procedural memory
  - - - critical for declarative memory functioning
      - important for spatial memory & contextual learning and binding
      - important for contextual learning
    - - impairs 2 types of tasks
        
        delayed matching-to-sample task
        
        delayed non-matching-to-sample task
      - impairs spatial tasks
        
        radial mazes
        
        Morris water maze task
      - impairs recent learning more than older learning
- - - - events increase probability response occur again
    - - event decrease probability response occur again
  - - - all cortex parts contribute equally to complex functioning behaviours
    - - cortex works as a whole
- - - - memory events that just occured
      - limited capacity
      - fades quickly without rehearsal
      - retrieval of lost memories don't benefit from presence of cue
    - - memory events from times further back
      - memories persist
      - unlimited capacity
      - memory can be stimulated with cue/hint
  - - - cause: changes in prefrontal cortex
      - declining activity of prefrontal cortex associated with memory decrease
- - - - cause: prolonged thiamine deficiency
        
        due to chronic alcoholism
        
        loss/shrinkage of neurons in brain
        
        symptoms
        
        forgetting
        
        apathy
        
        confusion
    - - gradual progressive loss of memory (declarative memory)
      - associated with accumulation and clumping of proteins
        
        amyloid beta protein
        
        accumulation of both proteins result in
        
        plaques
        
        tangles
        
        abnormal form of tau protein
