The Blue Brain Project proposes multi-dimensional neural sub-networks.

In 2015, the Blue Brain Project successfully created a digital version of a slice of a rat’s brain. The digital version contained some 31,000 neurons with around 8 million connections between them. The model has started to throw off interesting results. One proposed result is that some neural sub-networks contain such high levels of connectivity that they become multi-dimensional. Specifically, these sub-networks consist of more than the standard three dimensions. Intriguingly, however, such networks are temporary rather than fixed. They appear dimension by dimension with rising connectivity, peak and then collapse. The project leader, Henry Markram, thinks that maybe they even contain the answer to consciousness.
