Neural Maps show American Science at its best. But for how much longer?

If you want to explore the potential of a vast unknown region, first make a map of it. This why many of the finest minds from the sixteenth to the nineteenth century were cartographers. The human brain, with its astronomical numbers of circuits and connections, is our century’s equivalent of an unknown continent. Where the prizes( in medical research, pharmaceuticals and lucrative spin off disciplines) will go to those who have the best idea of the layout of the territory they are exploring. Which is why it came as no surprise to find that a multi-university team of American researchers have emerged as some of the foremost neurological cartographers of the year

Hannah Devlin of the Guardian reports the work of the teams from Baylor College, The Allen Institute and Princeton who have combined different techniques to create a 3-D circuit diagram of the neurons in a mouse brain. Now, there are some riders to note: this is only a tiny portion of the brain, comprising 84 000 neurons, half a billion synapses and about 5.4 km of the neuronal equivalent of wiring. Tiny numbers compared to the colossal sizes of a human brain, or that of an elephant or a dolphin. But it’s a start. Hannah quotes experts who honestly compare this work to the human genome project around the turn of the century. We need not remind readers as intelligent as ours of all the potential which that unlocked.

So: American researchers at the cutting edge. Princeton. Big research teams. “Yawn,” they said in the newsroom, “Where’s the story?” Well the story lies in the context of the consistent cuts in science funding by a certain Donald J Trump and his Administration. [2] It’s not just the money, it’s the attacks on the confidence and independence of the institutions themselves which stunt the development of a healthy research sector. And ultimately kill the goose which has laid so many eggs.(please-no more cliches!-ed) From the 1930s onwards America thrived by taking in the best researchers, and letting them work at what they excelled. Every science magazine you picked up, every episode of the old Horizon series on BBC, had an American somewhere in it. They even got to the Moon. Now there is a real danger that all that talent, all that potential will flow elsewhere. So far the EU and UK have not really go their act together. But they are waking up to the opportunity. Perhaps the first whole-brain maps will be made in Cambridge. The English one, that is.
