Most people find it difficult to understand our world as a single space-time entity with four dimensions: three of space (length-width-height) and one of the time.
One can imagine the headache caused by the announcement by scientists that they first discovered structures in the brain with up to 11 dimensions.
The neuroscientists of the Swiss “Blue Brain Project”, using original mathematics (algebraic topology in a way that has never been used in neuroscience), have shown that the human brain does not only function in three but in much more dimensions. This is an impressive claim that aspires to illuminate the deepest architectural secrets of the brain.
The researchers, headed by one of the world’s leading neuroscientists, Professor Henry Markram of Switzerland’s Lausanne Federal School of Engineering (EPFL) and director of the “Blue Brain Project” -who made the relevant announcement in “Frontiers in Computational Neuroscience” magazine- announced that they have uncovered a universe of multidimensional geometric structures within the brain networks.
These multi dimensional structures occur when each neuron is linked to others in such a way that a peculiar geometric object is created. The more neurons involved in the same “clique”, the larger the dimensions of this geometric object.
“We found a world we never imagined. There are tens of millions of such objects even in a small dot of the brain, having up to seven dimensions. In some brain networks, we found structures even with 11 dimensions”,
As he said, it probably explains why it’s so hard to understand the brain. Obviously, if man has a great difficulty in catching the four-dimensional world of Einstein (the space-time constant), worlds with more dimensions become too complex even for the most imaginative imagination.
The new revelation was made possible by the collaboration of neuroscientists with mathematicians who specialize in algebraic topology, a branch of mathematics that describes systems of any number of dimensions.
In 2015 the “Blue Brain Program” presented the first digital copy of a part of the neo-collar, the most advanced part of the brain.
In the context of the new study, with the aid of algebra topology, multiple tests on digital brain tissue have been performed, which have shown that the multidimensional structures of the brain that have been discovered may not have been created by chance.
Experiments on real brain tissue in EPFL followed, confirming that the brain is constantly “recalled” during its development to create a network with as many structures as possible.
For years, neuroscientists have been struggling to find where the brain stores its memories. As Mr. Markram said:
“they may eventually be hiding in cavities between the higher dimensions”.
The ambitious goal of the “Blue Brain Project” is to create -with the help of a supercomputer– exact digital representations and simulations of the brain of the rodents, initially and then of man.
