The information: A group led by scientists from Harvard and Google has created a 3D, nanoscale-resolution map of a single cubic millimeter of the human mind. Though the map covers only a fraction of the organ, it’s presently the highest-resolution image of the human mind ever created.
How they did it: To make a map this finely detailed, the group needed to lower the tissue pattern into 5,000 slices and scan them with a high-speed electron microscope. Then they used a machine-learning mannequin to assist electronically sew the slices again collectively and label the options.
Why it issues: Many different mind atlases exist, however most present a lot lower-resolution information. On the nanoscale, researchers can hint the mind’s wiring one neuron at a time to the synapses, the locations the place they join. And scientists hope it may assist them to essentially perceive how the human mind works, processes data, and shops recollections. Learn the total story.
