Methods For Investigating Connectivity

The excitable axonal membrane is specialized for the propagation and conduction of the nerve impulse. Via synaptic connections with dendrites and, to a lesser extent, neuronal somata and other axons, axons are the chief means of "information transfer'' within neural networks.

The organization of connectional systems has been investigated by a variety of experimental techniques, mostly in animal models. A large body of work has been devoted to simply mapping the complex interconnections of different structures. Much of this work has utilized extracellular injections tracer substances, which typically cover a tissue volume of 0.1-2.0 mm in diameter.
