Technique to make tissue transparent offers three-dimensional view of neural networks.


A chemical treatment that turns whole organs transparent offers a big boost to the field of ‘connectomics’ — the push to map the brain’s fiendishly complicated wiring. Scientists could use the technique to view large networks of neurons with unprecedented ease and accuracy. The technology also opens up new research avenues for old brains that were saved from patients and healthy donors. (...) - by Helen Shen, Nature News, 10 April 2013

Whole brain cellular-level activity mapping in a second

Whole brain cellular-level activity mapping in a second | Didactics and Technology in Education | Scoop.it

It is now possible to map the activity of nearly all the neurons in a vertebrate brain at cellular resolution. What does this mean for neuroscience research and projects like the Brain Activity Map proposal?

In an Article that just went live in Nature Methods, Misha Ahrens and Philipp Keller from HHMI’s Janelia Farm Research Campus used high-speed light sheet microscopy to image the activity of 80% of the neurons in the brain of a fish larva at speeds of a whole brain every 1.3 seconds. This represents—to our knowledge—the first technology that achieves whole brain imaging of a vertebrate brain at cellular resolution with speeds that approximate neural activity patterns and behavior.
