2023年8月9日 · Henry Gustav Molaison, known as Patient H.M., is a landmark case study in psychology. After a surgery to alleviate severe epilepsy, which removed large portions of his hippocampus, he was left with anterograde amnesia, unable to form new explicit memories, thus offering crucial insights into the role of the hippocampus in memory formation.

在H.M.进入神经科学史之前，受到卡尔·拉什利（Karl Lashley）影响，科学界普遍认为记忆功能广泛分布在皮层中，并与智力和感知功能整合在一起[2]。 随着对亨利研究的不断深入，科学家们证实了记忆是一种独特的脑功能，可以与其他感知和认知能力分离，并确定 ...

Discover the groundbreaking case study of HM, which revealed the essential role of the hippocampus in memory formation and challenged the concept of localization of function in the brain.

Milner conducted psychometric testing such as IQ testing. She tested HM's memory recall skills and learning skills. In particular, understand the mirror task. HM was required to complete the mirror task, which is an activity where he is unable to see his hand but can see it and the piece of paper through a mirror.

2018年8月28日 · In 1955, scientists William Beecher Scoville and Brenda Milner began studying Molaison — referred to as H.M. to protect his privacy — and nine other patients who had undergone similar surgery. Only patients who had specific portions of their medial temporal lobes removed experienced memory problems.

2021年3月22日 · Hers is a cognitive longitudinal case study of H.M.’s anterograde (after the surgery) and partial retrograde (before the surgery) amnesia. The biological part of the H.M. study is the correlation between the brain damage and the amnesia, which was assumed in the 1950s, and not verified until later brain scans in the 1990s (see Corkin, 1997)

2012年1月16日 · Henry Molaison, known by thousands of psychology students as "HM," lost his memory on an operating table in a hospital in Hartford in August 1953. He was 27 years old and had suffered from...

2024年9月25日 · Results: The key finding from the study of HM is that memory is not simply part and parcel of a collection of cognitive functions which reside in the cortex, rather it is a distinct function which is localised to the temporal lobe, specifically the hippocampus. Post-mortem analysis of HM’s brain helped to confirm these findings.

The study of Molaison revolutionized the understanding of the organization of human memory. It has provided broad evidence for the rejection of old theories and the formation of new theories on human memory, in particular about its processes and the underlying neural structures (cf. Kolb & Whishaw, 1996).
