My friend and colleague Dharmendra Modha’s new paper on the network architecture in monkey brain has just been published in the Proceedings of the National Academy of Sciences. His blog is here. For those with access, the paper itself is here.
Congrats to Dharmendra and Big Blue!
This is one of the crowning efforts in neuroinformatics. Read about it here (with links).
The Krasnow Institute, HHMI and the Allen Institute for Brain Science announced a grand challenge project today–to create better tools for image analysis.
The organizers hope the DIADEM Challenge—short for Digital Reconstruction of Axonal and Dendritic Morphology—will lead to innovative solutions to a frustrating problem that has slowed efforts to create a functional atlas of the brain. Neuroscientists agree that a systematic characterization of neurons with their dendrites and axons is essential, since these tree-like structures are highly correlated with the electric activity of, and precise connections between, neurons and are thus linked to the functions of specific brain circuits. But scientists currently spend weeks—and, in some cases, months—tracing the intricate neuronal processes by hand, using data supplied by imaging studies.
