An infection damaged his hippocampus, + frontal and temporal lobes. He is left mainly with just his consciousness of his own existence.

lesions of certain auditory cortical regions result in an unusual phenomenon: a highly selective problem with perceiving and interpreting music, termed ‘amusia’
People with this type of damage have no problem speaking or understanding speech, or making sense of everyday sounds. But they cannot notice wrong notes inserted into tunes, or recognize even the most familiar melody. Even more surprising is that a minority of otherwise normal individuals appear to be born with the same inability to recognize tunes. In some cases, the deficit seems to run in families, suggesting a genetic component.
Brain’s ‘addiction centre’
The discovery of individuals with brain damage who give up smoking with ease could point the way to a surgical ‘cure’ for smoking, US scientists say. The particular brain area damaged – called the insula – appears to be central to the urge to smoke, a team told the journal Science.
The insula receives information from other parts of the body and is thought to help translate those signals into something that is subjectively felt, such as hunger, pain, or a craving. Dr Bechara’s team studied 69 brain-damaged smokers – 19 who had suffered insula injury.
A man with an unusually tiny brain managed to live an entirely normal life despite his condition, caused by a fluid buildup in his skull, French researchers reported on Thursday.
Scans of the 44-year-old man’s brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue.
“He was a married father of two children, and worked as a civil servant,” Dr. Lionel Feuillet and colleagues at the Universite de la Mediterranee in Marseille wrote in a letter to the Lancet medical journal.
