To publish the most complex full synaptic map of the brain to date, the researchers applied high spatial resolution and artificial intelligence techniques to reconstruct the complete map of the fly larva's brain.

The resolution of this map is such that it can not only visualise major highways and the cities they connect, but also secondary roads, smaller towns and even gas stations, toll booths and lighting points.  

The size of the fly's brain compared to the human brain is like comparing a grain of sand to the whole desert, but this kind of approach will allow us to understand the basic principles that govern communication in the brain and to determine whether there are alterations that may influence its functioning. There are still many grains of sand to be discovered in the human brain!
