It is now intriguing to suggest that microtubules can resemble the so-called “Majorana zero modes (MZMs)”, which are topologically protected degeneracy in the presence of certain topological defects \cite{You_2012}. If biology can provide a mechanism to braid those MZMs then we know that mechanisms in the brain exist which could perform quantum computing, which is remarkable. However, as mentioned before, most cognitive functions are performed on larger temporal and spatial scales involving ensembles of cells. Therefore, it is likely that MZMs in the cell cytoskeleton are important for computation inside the cell but not for higher brain functions.
