There is a forest in our heads – soaring trunks and twining branches composing an entire interconnected system. A spark, a pulse, and the branches lit up as the message speeds past in less than a microsecond. This network of nerves, dendrites, axons, and somas make up our connectome. Similar to the genome, this new concept stems from the research of Dr. Sebastian Seung of MIT’s Brain and Cognitive Science Department. He has started an ambitious project to map all the connections between neurons – the nerve cells that are responsible for our every movement and thought.
