Study Notes
Memory Types
- LTM (Long-Term Memory): A type of memory that stores information for extended periods, categorized into declarative and nondeclarative.
- Declarative Memory (Explicit): Consciously accessible memory, further divided into episodic and semantic memory.
- Episodic Memory: Memory of personal experiences and events; includes details about time and context.
- Semantic Memory: Memory of facts and general knowledge; does not include personal experiences.
- Nondeclarative Memory (Implicit): Unconscious memory, encompassing procedural, perceptual, and classical conditioning.
- Procedural Memory: Memory of skills and habits; how to perform actions.
Memory Processes
- Encoding: Processing incoming information and converting it into a memory representation.
- Acquisition: The initial process of gaining information, including selection (choosing relevant data) and consolidation (strengthening memory traces).
- Storage: Maintaining and preserving encoded information.
- Retrieval: Accessing and recalling stored memory.
Memory Anatomy
- Medial Temporal Lobe (MTL): Crucial for long-term memory, including the hippocampus and surrounding structures.
- Hippocampus: Essential for spatial navigation and converting short-term memories into long-term memories.
- Amnesia: Impairment of memory, categorized into retrograde (loss of past memories) and anterograde (inability to form new memories) types.
Memory Mechanisms
- Sensory Memory: Initial, brief storage of sensory information; includes iconic (visual) and echoic (auditory) memory.
- Short-Term Memory (STM): Holds a limited amount of information temporarily; crucial for conscious processing and rehearsal.
- Working Memory: Active maintenance and manipulation of information in STM; essential for complex tasks like reasoning and problem-solving.
- Models of Working Memory (e.g., Baddeley & Hitch): Working memory models describe its components including phonological loop and visuospatial sketchpad, with a central executive for control.
- Long-Term Memory: A long-term store of information organized into networks or associations.
Priming
- Priming: A change in responses to stimuli caused by prior exposure to similar stimuli.
- Perceptual Priming: Affects perceptual recognition based on prior exposure.
- Conceptual Priming: Affects higher-level cognitive processing from prior exposure.
Consolidation
- Consolidation: The process of stabilizing and strengthening memory traces; includes both temporary and long-term consolidation.
Long-term Memory Study (Rodent Studies)
- Rodent Studies: Using animal models to investigate how memories form and are stored in the brain, often involving hippocampal roles in spatial learning.
- Encoding and Retrieval: Encoding involves transforming information into a neural code, while retrieval involves accessing that information.
- Recollection and Familiarity: Two distinct processes—recollection (conscious recollection) and familiarity (subconscious awareness of previously encountered information)—in memory.
Episodic Memory (Contextual Memory)
- Episodic Memory: Memories of particular events associated with context (time and place).
- Explicit Memory: Declarative memories that are consciously available.
- Neural Substrates: The regions of the brain involved in encoding and storing episodic memories, primarily the hippocampus and associated cortical areas.
False Memories
- False Memories: Memories that are not accurate reflections of past events.
Memory Disorders (e.g., Alzheimer's, Huntington's, Parkinson's)
- Neurological Disorders: Brain diseases like Alzheimer's and Huntington's cause various memory problems.
