The complexities of the human brain have boggled the mind of researchers since time unknown who find it difficult to comprehend it even today. As if the previous dilemma of how the neural structure responds to and how it is linked to human response was not enough, a new layer is added to what we currently know about the cybernetics of brain.
The way in which neurons connect to each other leads to a specific geometry. The complex web of neurons and their density inside the structure decides the dimension associated with that group. With the initiatives and the research efforts of the Blue Brain project, a Swiss national brain initiate to obtain digital reconstructions of the human brain at biological detail level, within a virtual brain tissue the geometry of the cliques(group of neurons) or neural structures having 5, 6, 7 and even up to 11 dimensions have been found.
A three-dimensional space or time space reality is the one in which we observe events in a linear fashion that is one after the other. But, if you are confused about why and how the higher dimensional structures serve a useful purpose then let me tell you that “they hold the mystery behind the past, present, and future events”. Not only this but also the missing link between the stimuli and response can be decoded.
Deep consciousness study tells us that all the events past, present and future occur simultaneously but our perception is only able to see the 3D space. This groundbreaking research will pave the way for the question “How brain network allows us only to live in present? And why we are not able to see past and future as well?
Whenever brain is presented with information, first the family of neurons get fired moving to the group of these families and then ultimately creating an encoding pattern to store the information and reach to the decision of what the final action is to be taken.
For the experiment conducted at the lab in Lausanne, blue brain researchers used a real brain tissue of the most evolved part of the brain-the neocortex. Upon stimuli, the cliques associated with higher dimensions arranged themselves to enclose higher dimensional holes or cavities, behaving in a highly organized manner. These ephemeral holes lasted only till the brain processed the information and have attracted several speculations, one being the storage of memory.
“They may be ‘hiding’ in high-dimensional cavities,” Markram speculates.
With the recommendations of Kathryn Hess from EPFL and Ran Levi from Aberdeen University, the algebraic branch of mathematics which can be applied to study any number of dimensions is being used.
“Algebraic topology is like a telescope and microscope at the same time. It can zoom into networks to find hidden structures – the trees in the forest – and see the empty spaces – the clearings – all at the same time,” explains Hess
Thus the researchers have moved one step ahead in analyzing the complexities of the brain which we can harness in future to fully utilize the true potential of our brain.
