    Study Notes

    Memory and the Brain

    • The temporal lobe is primarily responsible for memory processing.
    • The Multi-Store Memory Model by Atkinson and Shiffrin describes how information is processed and stored in the brain.
    • Attention is crucial for remembering information, allowing us to focus on select stimuli.
    • Sensory memory initially encodes sensory information, but has a short duration and limited capacity. It is responsible for filtering out unimportant information.
    • Short-term memory (STM) temporarily holds information for immediate use, lasting approximately 20 seconds without rehearsal. Rehearsal, the process of repeating information verbally or mentally, helps retain information in STM.
    • Long-term memory (LTM) is an unconscious storage system with unlimited capacity. Information is stored for long periods and requires cues for retrieval into STM.
    • The Working Memory Model consists of:
      • Phonological Loop: Processes and rehearses verbal information.
      • Visuospatial Sketchpad: Processes and rehearses visual information.
      • Central Executive: Controls attention and shifts focus.
      • Episodic Buffer: Integrates information from other working memory components and interacts with long-term memory.
    • The hippocampus, located in the temporal lobe, is crucial for memory consolidation.
      • It is part of the limbic system, which is associated with emotions, explaining the strong link between memory and emotions.
    • The amygdala, located above the hippocampus, is primarily involved in processing emotions but is also highly activated during memory recall, especially with fear-related memories.
    • The sense of smell is directly connected to the hippocampus through the olfactory bulbs, strengthening the association between smell and memory.
    • The cerebellum plays a significant role in procedural memory and motor learning.

    Amnesia

    • Retrograde amnesia: Loss of memory for events or information that occurred before the onset of a brain injury or neurological condition.
    • Anterograde amnesia: Impairment in forming new memories after the onset of a brain injury or neurological condition.
