Billions of dollars to map billions of neurons

A lot of money is being spent right now to ‘map the human brain’. In the last month, both the European Commission and U.S. president Barack Obama have pledged to give billions of dollars to fund two separate projects geared towards creating a working model of the human brain, all 100 billion neurons and 100,000 billion synapses.

The first, the Human Brain Project, is being spearheaded by Prof Henry Markram of École Polytechnique Fédérale de Lausanne. Together, with collaborators from 86 other European institutions, they aim to simulate the workings of the human brain using a giant super computer.

To achieve this, they will work to compile information about the activity of tons of individual neurons and neuronal circuits throughout the brain in a massive database. They then hope to integrate the biological actions of these neurons to create theoretical maps of different subsystems, and eventually, through the magic of computer simulation, a working model of the entire brain.
