The man who constituted one of the best explored case studies in cognitive psychology, perhaps the best explored case study ever, has passed away. As reported in the Montreal Gazette:
The 82-year-old man scientists have known only as HM died of heart failure Tuesday after decades in a Connecticut chronic care home, unaware of what he gave to science.
In short, H.M. suffered intractable epilepsy for which he underwent a removal of large portions of his temporal lobes. Although successful in curbing his seizures, the procedure resulted in a anterograde memory loss resulting in an individual stuck in time. The rather selective nature of his impairment led to a huge number of investigations and information on the neuronal basis of various processes that we think of under the general term"memory".
RIP, H.M., voluntarily or not you are a lion of science.
