 Einstein's brain was preserved after his death, but this fact not revealed until 1978. The brain of Albert Einstein has often been a subject of research and speculation. Einstein's brain was removed within seven hours of his death. The brain has attracted attention because of Einstein's reputation for being one of the foremost geniuses of the 20th century, and apparent regularities or irregularities in the brain have been used to support various ideas about correlations in neuroanatomy with general or mathematical intelligence.

Preservation of Einstein's brain Einstein's brain was removed, weighed and preserved by Thomas Stoltz Harvey, the pathologist who performed the autopsy on Einstein. He claimed he hoped that cytoarchitectonics would reveal useful information. [1] Harvey injected 10% formalin through the internal carotid arteries and afterwards suspended the intact brain in 10% formalin. Harvey photographed the brain from many angles. He then dissected it into roughly 240 blocks (each about 10cm3) and encased the segments in a plastic-like material called celloidin. [2][3] Harvey may also have removed Einstein's eyes, and given them to Henry Abrams. [4] He was apparently fired from his position at Princeton University shortly thereafter for refusing to relinquish the organs. Dr. Thomas Stoltz Harvey (born October 10, 1912) is a pathologist who conducted the autopsy on Albert Einstein in 1955. ...

Disputed consent Whether Einstein's brain was removed and preserved after his death in 1955 with his permission is a matter of dispute. Ronald Clark's 1971 biography of Einstein said that "he had insisted that his brain should be used for research and that he be cremated", but more recent research has suggested that this may not be true at all, and that the brain was removed and preserved without either Einstein's immediate permission or the permission of his close relatives (Einstein, Walter Isaacson). Hans Albert Einstein, the physicist’s son, agreed to the removal after the event but insisted that his father’s brain should be used only for scientific research to be published in scientific journals of high standing.[5] Hans Albert Einstein (May 14, 1904 – July 26, 1973) was a Professor of hydraulic engineering at the University of California, Berkeley, and the first son of renowned physicist Albert Einstein (1879-1955) and his first wife Mileva Marić (1875-1948). ...

Nevertheless, when Einstein's brain was rediscovered in 1978 after being stored in mason jars within a cider box for over 20 years, it aroused considerable popular and scientific attention. Year 1978 (MCMLXXVIII) was a common year starting on Sunday (link displays the 1978 Gregorian calendar). ...

The brains of other geniuses Preserving the brains of geniuses was not a new phenomenon—another famous brain to be preserved and discussed in a similar manner was that of the German mathematician Carl Friedrich Gauss almost a hundred years earlier. His brain was studied by Rudolf Wagner who found its weight to be 1,492 grams and the cerebral area equal to 219,588 square centimeters. Also found were highly developed convolutions, which was suggested as the explanation of his genius (Dunnington, 1927). Other famous brains that were removed and studied include that of Vladimir Lenin and the Native American, Ishi. The brain of Edward H. Rulloff, philologist and "criminal of superior intelligence," was removed after his death in 1871; in 1972, it was still the second largest brain on record (New York Times, Nov. 7, 1972, p. 37).

Study finding part of Einstein's brain missing and another part 15% larger However, in 1999, further analysis by a team at McMaster University in Ontario revealed that his parietal operculum region in the inferior frontal gyrus in the frontal lobe of the brain was vacant. Also absent was part of a bordering region called the lateral sulcus (Sylvian fissure). Researchers at McMaster University speculated that the vacancy may have enabled neurons in this part of his brain to communicate better. "This unusual brain anatomy…(missing part of the Sylvian fissure)… may explain why Einstein thought the way he did," said Professor Sandra Witelson who led the research published in The Lancet. Einstein himself claimed that he thought through images rather than verbally. Professor Laurie Hall of Cambridge University commenting on the study, said, "To say there is a definite link is one bridge too far, at the moment. So far the case isn't proven. But magnetic resonance and other new technologies are allowing us to start to probe those very questions."

Scientists are currently interested in the possibility that physical differences in brain structure could determine different abilities. [7] [8]One famous part of the operculum is Broca's area which plays an important role in speech production (see below for discussion relating to Einstein's difficulties with language). To compensate, the inferior parietal lobe was 15 percent wider than normal. [9] The inferior parietal region is responsible for mathematical thought, visuospatial cognition, and imagery of movement. Einstein's brain also contained 73 percent more glial cells than the average brain. Brocas area is the section of the human brain (in the opercular and triangular sections of the inferior frontal gyrus of the frontal lobe of the cortex) that is involved in language processing, speech production and comprehension. ...

Study finding more glial cells in Einstein's brain In the 1980s, University of California, Berkeley professor Marion C. Diamond persuaded Thomas Harvey to give her samples of Einstein's brain. She compared the ratio of glial cells in Einstein's brain with that in the preserved brains of 11 men. Her laboratory made thin sections of Einstein's brain, each 6 micrometers thick. They then used a microscope to count the cells. Einstein's brain had more glial cells relative to neurons in all areas studied, but only in the left inferior parietal area was the difference statistically significant. This area is part of the association cortex, regions of the brain responsible for incorporating and synthesizing information from multiple other brain regions. Diamond admits a limitation in her study is that she had only one Einstein to compare with 11 normal men. S. S. Kantha of the Osaka BioScience Institute in Japan criticized Diamond's study, as did Terence Hines of Pace University.

Diamond and Joseph Altman (then of Purdue University) had already both discovered that rats with enriched environments developed more glial cells for each neuron. Rats in impoverished environments had fewer glial cells relative for each neuron. [11] A lifetime studying difficult mathematical and physical problems may have enriched Einstein's environment.
