If successful, the project could also help explain the origins of autism, schizophrenia, dementia and depression. The scientists argue that the project would help develop technology such as nanoscale neural probes that could be used in the clinical treatment of brain problems.

Within five years, the researchers write, scientists should be able to monitor tens of thousands of neurons at once - within 10 years, hundreds of thousands.īy year 15 of the project, the researchers plan to be able to monitor million-neuron networks, the size of an entire zebrafish's brain. The plan, as laid out in the journal Science, is to begin with small-brained invertebrates and move up in brain complexity. ![]() Scientists also need tools to alter the action of individual neurons in a circuit in order to test the effects of a single cell on the whole system. To find out, Yuste and his colleagues say, researchers must be able to monitor whole, interacting networks of neurons at once. How do neurons work together in networks? What happens when the brain's circuitry breaks down? They can watch the whole brain in action using functional magnetic resonance imaging (fMRI) and other techniques. Currently, scientists can monitor the activity of a single neuron using electrodes. ![]()
