Albert Einstein was the one to beat. Although, there have aroused numerous scientists with capabilities higher than a normal human being, Einstein is still the one to beat. Numerous studies have taken place over the course of time disproving the previously laid statements of every scientist who had worked with the brain of Einstein until the work of Sandra Witelson. She had presented a paper “The exceptional brain of Albert Einstein” in 1999, stating that “the brain of Einstein was found with largely absent Sylvian fissure which usually segregates the parietal lobe”

“Without the segregation, parietal lobe of Einstein’s brain was found 15 percent wider than an average human brain.”

        This influenced the brain of Einstein as the wide parietal lobe had accounted for his spatial reasoning, mathematical ability and 3-D visualization.

It was also inferred that this modification in brain might have brought about his “delayed speech development”. Theories have been constantly disapproved with the arrival of new scientists and new effective theories. There might be even more to the brain of Einstein; more than what Sandra had discovered.


“Words do not seem to play any roles”


Well, they certainly don’t as his brain does the work that needs to be done!



The advent of diamonds in the neurological field has brought upon a squall. A team of three interdisciplinary researchers, Dirk Englund, assistant professor of electrical engineering and of applied physics at The Fu Foundation School of Engineering and Applied Science, Jonathan S. Owen, assistant professor of chemistry, and Rafael Yuste, professor of biological sciences and neuroscience were recently awarded 1 million dollars from the W. M. Keck Foundation to develop their research on the imaging of neuronal signals using diamond nano probes. The neurons were tightly packed as in the case of Einstein’s brain and this study of neuronal signals could enhance the study of brain cells and could probably bring about changes in the theory of Sandra Witelson.



Diamonds are generally hard and are suitable for various bio medical applications and their structure explains the reason behind this. Diamond nano particles of ~5 nm in size provide a large operative surface and modifiable surface chemistry. They have unique optical, mechanical and thermal properties and are non-toxic.


These scanning electron micrograph images of (a) nano crystalline diamonds and (b) ultra nano crystalline diamonds depict the thickness variation which determines the medical applications of these materials.

The ultra nano crystalline diamonds are advantageous as they can be deposited even at lower temperatures, allowing it to be used for “micro electro mechanical systems” and “nano electro mechanical systems”; besides, these diamonds are chemically inert and are very compatible with living cells.



It is definitely not a wieldy job to visualize the functioning of entire neuronal groups while preserving the single cell resolution.

“The optically manipulated color centers in the ultra nano crystalline diamonds might be the possible solution”

This could ameliorate the resolution as these diamonds are the “world’s most sensitive magnetic and electric field probes”.

The electrical activity of the neurons can be visualized for a targeted brain tissue as these “nano-diamonds act as excellent sensors”. The activity of brain can be studied with high efficacy as the individual neurons within the neuronal circuits can be captured.



The researchers at MIT have formulated a notion that the “usage of diamonds are extremely non-invasive”. They cause no damage to the living cells as “diamonds are mainly composed of carbon”. The previously used invasive method to study the communication of neurons had proven to be harmful for the living cells as researchers used electrodes to poke the neurons and measure the corresponding electric field produced.


There is a nitrogen vacancy present (N-V) in the diamond as shown in the figure. These centers are naturally occurring defects in a diamond and can be very sensitive to magnetic fields. So, by the passage of micro waves, the magnetic fields generated by the biological sources can be measured.

Surprisingly, “these diamond nano-probes can also be used to measure the magnetic fields produced by Meta materials that are used to make super lenses and invisibility cloaks”.

The team at MIT used wave guide (as an artificial neuron) and applied an external magnetic field. When they placed the diamond sensor on the wave guide, they were able to scrupulously reconstruct the magnetic field.

“This could measure the neural signals of the brain meticulously”

“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less”.
-Madam Curie


As, the powerful woman of Science era points out the intimacy of comprehension, Einstein’s brain is nothing to be feared of, it is only to be understood. With, highly advanced technology, “Science is a play toy of every ambitious mind” and Einstein’s brain is no exception. Sooner or later, there will be new findings, immersing the theories of Sandra.

“Shine bright like a diamond”


The popular singer had written this power-ballad lyrical line for Rihanna as she had pointed out the aesthetical importance of a diamond but not much was she able to realize the monumental value of these diamonds. They are now proving to be the golden treasures in the various fields of technology.

We will get to know more secrets behind Einstein’s brain in the near future through diamond nano probe sensors.”
