Cortical Neurons

Largest network of cortical neurons mapped from ~100 terabytes data set
April 1, 2016

A network of cortical neurons whose connections were traced from a multi-terabyte 3D data set. The data were created by an electron microscope designed and built at Harvard Medical School to collect millions of images in nanoscopic detail, so that every one of the “wires” could be seen, along with the connections between them. Some of the neurons are color-coded according to their activity patterns in the living brain. This is the newest example of functional connectomics, which combines high-throughput functional imaging, at single-cell resolution, with terascale anatomy of the very same neurons.

"Functional connectomics" research bridges gap between function and wiring in the brain --- a major step in an IARPA project to create a roadmap for reverse-engineering the brain
The largest network of the connections between neurons in the cortex to date has been published by an international team of researchers from the Allen Institute for Brain Science, Harvard Medical School, and Neuro-Electronics Research Flanders (NERF). In the process of their study*, the researchers developed new tools that will be useful for “reverse engineering … more…
