H.M. Case Study
Grand Canyon University
PSY 560 Learning, Cognition, and Motivation
Introduction
The case of H.M. is pivotal in neuroscience and psychology. Due to epilepsy, H.M. was
an individual who underwent surgical removal of parts of his medieval temporal lobes, including
the hippocampus. The surgery resulted in profound amnesia, providing crucial insights into the
functioning of the memory. Despite his severe memory impairment, H.M. learned new motor
skills, leading to distinction between different memory systems. The study of H.M.’s case has
influenced our understanding of memory, systems, and the neural basis of memory, shaping the
direction of memory research.
Neurological Explanation
H.M., He suffered from severe memory impairment due to the bilateral removal of the
medial temporal lobes, including the hippocampus, to treat epilepsy. The bilateral removal of the
medial temporal lobe, including the hippocampus, to treat epilepsy in Henry Molaison (H.M.)
, resulting in severe memory impairment. The anterograde amnesia, H.M. could not create new
memories, but his working and procedural memory remained intact. The study of H.M. led to
significant insights into memory organization and the medial temporal lobe's involvement in
memory functions. It also helped to understand different memory systems, such as declarative
