Nanowire Tetrodes

This would be great to use to find out exactly how neuroplasticity recruits new neurons and how axonal growth connects up neurons.
I emailed the professor letting him know what this could solve on neuroplasticity and neurogenesis.

The tip of an electrode, one-tenth the width of a human hair, with 18 nanowires drawn off from it. Each nanowire is one micron long and 60 nanometers wide (six-thousandths as wide as a human hair).

The project appears blandly nondescript. "Nanowire Tetrodes."
But what it seeks to do -- develop a wire so thin it can harmlessly penetrate the cell of a neuron to listen to what happens when a rat makes a decision -- could make a lot of noise if successful. Such knowledge could form the foundation for all kinds of therapies.
