Study Notes
Introduction
- Clive Wearing, a musician, suffered from herpes simplex encephalitis in 1985, which damaged his medial temporal lobes, especially the hippocampus.
- This resulted in severe retrograde and anterograde amnesia, affecting his episodic memory, the ability to recall events.
- Clive Wearing's episodic memory is limited to 20-30 seconds, making him experience a continuous “present” moment.
- His case demonstrates the profound impact of memory impairment on human experience and functionality.
- Henry Molaison (“HM”), a patient who underwent a bilateral hippocampectomy to treat epilepsy, also suffered from temporally graded retrograde and anterograde amnesia for episodic memory.
- However, other forms of memory, like semantic memory (facts) and procedural memory (motor skills), remained intact in HM.
- HM's case provided valuable insights into the nature of different memory systems.
Memory Systems
- The modal model of memory emphasizes that memory functions in a sequential manner, encompassing a Sensory Register, a Short-Term Memory (STM), and a Long-Term Memory (LTM).
- The model originates from the computer metaphor, and has been influential in research, but its limitations are evident.
- The model emphasizes static stores of memory, but current understanding suggests that memory processes are dynamic and interdependent.
- The model does not account for the bidirectional nature of memory, where long-term memory influences current perception and processing.
- Furthermore, the model does not align with the complex brain structures and functions implicated in memory, such as the hippocampus, which plays a key role in episodic memory.
