        where does it function at

        consolidation
        
        description
        
        stabilizes the memory
        
        how long does this take

        retrieval
        
        description
        
        recognizing patterns
      - what is it called when you have failure of memory abilities
        
        amnesia

        Skilled movements and habits
      - location in the brain (3)
        
        Frontal cortex, thalamus, and basal ganglia.
      - aka
        
        Unconscious (implicit) memory
      - is muscle memory real
        
        NO!
      - 3 phases
        
        cognitive
        
        description
        
        Focuses on actively thinking about each step of the skill, often requiring verbal instructions and conscious attention to detail
        
        associative
        
        description
        
        Connections between different steps and parts of the brain become more automatic, with less reliance on conscious thought
        
        autonomic
        
        description
        
        The skill becomes highly proficient, performed almost unconsciously with minimal cognitive effort

        how does these areas contribute to working memory
        
        these areas and their white matter are the neural substrate for working memory
      - essential for what 3 things
