Imaging Neurons



From Wired:
Masses of Neurons Coordinating Movement

Understanding neuronal connections could shed light on psychiatric disorders like schizophrenia that scientists believe arise from "wiring" problems.

"Our ultimate goal is to create automated systems that will take a sample of brain tissue as input and generate its 'circuit diagram,' a list of all its neurons and their synaptic connections, said Sebastian Seung, an MIT professor.
