Neuroscientists have begun testing the most powerful brain imaging technology ever created, and it’s already helped them answers questions about how connections form in our most complex organ.
The new imaging tool allows researchers to probe into every nook and cranny of the brain and then use the data to produce images at the nanoscale, like the one in the video above.
A large collective of researchers at Harvard, John Hopkins, and other institutions tested out the new technology by inspecting a mouse’s neocortex, according to a paper published Thursday in Cell. With such detailed imaging, every cellular object in the mouse’s neocortex (that would be the axons, dendrites, and glia, if you haven’t had a biology refresher in a while) were distinguishable and most of the sub-cellular components, such as synapses and spines, were visible as well.
