The first mapping of the human brain at the nanometer scale reveals the invisible!

Researchers have mapped all the neuronsneurons and their connections in a human brain sample. A very small sample to be exact, since it only measures one cubic millimeter, or one millionth of a complete brain. But this is the first such detailed mapping, carried out on the scale of the nanometernanometer. This is the work of a group of researchers from Harvard University and GoogleGoogle Research, who published their results in the journal Science.

From one perspective, our data set is tiny. But it doesn’t seem small, because when you dive into it, you realize that it is a gigantic forest. It’s a very small forest, but it’s a very, very, very complicated forest. “, said Jeff Lichtman, professor of molecular biologymolecular biology and cellular.

1.4 petabytes of data!

The sample is composed of approximately 57,000 cells, 230 millimeters of blood vessels, 150 million synapsessynapses, and represents 1.4 petabytes of data. This is the result of ten years of work. The sample was collected over a decade ago from a patient during a surgery related toepilepsyepilepsyand the data analyzed using Google’s artificial intelligence algorithms.

The researchers published all of their data in an online tool. These resources could help better understand the brain and human behavior and neurological disorders. However, as this sample comes from an epileptic patient, researchers do not know whether certain structures discovered are pathologicalpathological or simply rare.

A complete map of the brainbrain human with this level of detail is not yet achievable with current technology. However, researchers hope to eventually be able to map the brain of a mouse. In the meantime, the next step will be to study the hippocampal formation of a mouse.
