These Stunning Images Will Take You On A Journey Through The Brain
Harvard University scientists have discovered a new world of mystery and complexity at the micro level of the brain.
A new study authored by molecular biologist Dr. Jeff Lichtman and his colleagues and published last week in the journal Cell offers a glimpse inside the neurons of a mouse’s brain in unprecedented detail.
Lichtman told The Huffington Post that 20 scientists worked on the six-year project, with the aim of developing high-resolution images of the animal’s brain in an effort to better understand this complex organ.
The scientists developed technologies that created digital models of the actual brain tissue of mice, allowing researchers to examine its detailed structural organization.
In a series of 3D graphic images, the researchers were able to reconstruct components of an adult mouse’s brain at nanoscale resolution. They focused specifically on the brain’s neocortex, the outermost layer, which makes up roughly three-quarters of the brain’s volume. The neocortex comprises gray matter, the tissue made up of neurons that acts as an information-processing center.
“The goal of this study was to help us fathom this most mysterious part of biology,” Lichtman said in a Harvard video about the research. “Our goal in this case was to do that by looking at brains and describing them at very high resolutions.”
Using the new imaging technique, the researchers collected tens of thousands of ultra-thin brain sections — each one-thousandth the thickness of a single strand of hair — on a single film strip. They were able to create images of these sections at high resolution by using new software tools to color the neural connections.
