Parts of Al­bert Ein­stein’s brain are visibly un­like those of most peo­ple and this could help ac­count for his ge­nius, ac­cord­ing to a new stu­dy.

In it, Flor­i­da State Uni­vers­ity ev­o­lu­tion­ary an­thro­po­l­o­gist Dean Falk and col­leagues de­scribe for the first time the en­tire cer­e­bral cor­tex, or out­er lay­er, of Ein­stein’s brain from an ex­amina­t­ion of 14 re­cently dis­cov­ered pho­tographs.

The re­search­ers com­pared the path-break­ing phys­i­cist’s brain to 85 “nor­mal” hu­man brains and, in light of cur­rent im­ag­ing stud­ies, in­ter­preted what they called its un­usu­al fea­tures. They ex­am­ined re­la­tive sizes of dif­fer­ent sec­tions and the pat­tern of sulci, or sur­face folds.

“Although the over­all size and asym­met­ri­c shape of Ein­stein’s brain were nor­mal, the pre­fron­tal, so­matosen­sory, pri­ma­ry mo­tor, pa­ri­e­tal, tem­po­ral and oc­cip­i­tal cor­ti­ces were ex­tra­or­di­nary,” said Falk, re­fer­ring to spe­cif­ic sec­tions of the cer­e­bral cor­tex.

The pre­fron­tal cor­tex is known as the seat of cog­ni­tive anal­y­sis and ab­stract thought, and is some­times re­ferred to as the “CEO of the brain.” Spe­cif­ic parts of Ein­stein’s pre­fron­tal cor­tex are “rel­a­tively ex­pand­ed,” Falk and col­leagues wrote, “which may have pro­vid­ed un­der­pin­nings for some of his ex­tra­or­di­nary cog­ni­tive abil­i­ties.”

These same brain ar­eas are as­so­ci­at­ed “with the emer­gence of high­er cog­ni­tive abil­i­ties” in ev­o­lu­tion, they added.

The find­ings were pub­lished Nov. 16 in the jour­nal Brain.

The part of Ein­stein’s cer­e­bral cor­tex—the occi­pe­tal lobe—as­so­ci­at­ed with the pro­cess­ing of vis­u­al in­forma­t­ion was “very con­vo­lut­ed” com­pared to the av­er­age, Falk and col­leagues not­ed. This may have re­flected ex­tra pro­cess­ing pow­er for ment­ally vis­u­alizing things, they sug­gested.

Up­on Ein­stein’s death in 1955, his brain was re­moved and pho­tographed from mul­ti­ple an­gles with the per­mis­sion of his fam­i­ly. Fur­ther­more, it was sec­tioned in­to 240 blocks from which mi­cro­scope slides were pre­pared. A great ma­jor­ity of the pho­tographs, blocks and slides were lost from pub­lic sight for more than 55 years. The photos used by the re­search­ers are held by the Na­t­ional Mu­se­um of Health and Med­i­cine in Sil­ver Spring, Md.

The pa­per al­so pub­lishes a “roadmap” to Ein­stein’s brain pre­pared in 1955 by the phy­si­cian Thom­as Har­vey to il­lus­trate the loca­t­ions with­in Ein­stein’s pre­vi­ously whole brain of 240 dis­sect­ed blocks of tis­sue.

WARNING FROM RAEL: For those who don't use their intelligence at its full capacity, the label "selected by RAEL" on some articles does not mean that I agree with their content or support it. "Selected by RAEL" means that I believe it is important for the people of this planet to know about what people think or do, even when what they think or do is completely stupid and against our philosophy. When I selected articles in the past about stupid Christian fundamentalists in America praying for rain, I am sure no Rael-Science reader was stupid enough to believe that I was supporting praying to change the weather. So, when I select articles which are in favor of drugs, anti-semitic, anti-Jewish, racist, revisionist, or inciting hatred against any group or religion, or any other stupid article, it does not mean that I support them. It just means that it is important for all human beings to know about them. Common sense, which is usually very good among our readers, is good enough to understand that. When, like in the recent articles on drug decriminalization, it is necessary to make it clearer, I add a comment, which in this case was very clear: I support decriminalizing all drugs, as it is stupid to throw depressed and sad people (as only depressed and sad people use drugs) in prison and ruin their life with a criminal record. That does not mean that there is any change to the Message which says clearly that we must not use any drug except for medical purposes. The same applies to the freedom of expression which must be absolute. That does not mean again of course that I agree with anti-Jews, antisemites, racists of any kind or anti-Raelians. But by knowing your enemies or the enemies of your values, you are better equipped to fight them. With love and respect of course, and with the wonderful sentence of the French philosopher Voltaire in mind: "I disapprove of what you say, but I will defend to the death your right to say it".

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
