Researchers at Harvard have develped a device that allows them to slice brain tissue ultra-thin and then scan it with an electron microscope in order to create a complete mapping of the cell kinds and connections in a mouse brain (wired story here). The resulting map is called a connectome…very cool. This kind of research is exactly what we need in order to move forward in our quest to fill in the theoretical place-holder term ‘brain state’.
On a related note it also brings us one step closer to being able to end our relience on real animals to do chemical manipulations/lesions in. If these can be simulated a lot of animal suffering could be stoped.
