Does anyone know what they mean by a "grid"? Different neurons can have different numbers of connections and they connect all over the place, not just to their immediate neighbors.
I read and reread the first page of this paper and I can't figure out what they're saying. What's new here?
- nooneelse 15y agoI'm no domain expert, but I think by talking about individual neurons your comment is focused a bit too spatially small. The pathways described in the paper involve numerous axons hooking up widely separated neuron sets. I.e. for a computer analogy, this isn't showing the scale of internal wiring for a chip, or even cables on the scale of hooking the motherboard to a hdd. It is showing the wiring on the scale of 'from one rack in a sever room to another across the room'. Or, for a highway analogy, not the housing subdivisions, more the freeways. I just got answered over on reddit by someone who did a thesis on tractography; they seem to be open to more questions: http://www.reddit.com/r/science/comments/rl1y7/diffusion_spectrum_imaging_reveals_an_orderly/c46qbdg http://www.reddit.com/r/science/comments/rl1y7/diffusion_spe...
