"Jan. 18, 2013 — Activating and deactivating individual nerve cells in the brain is something many neuroscientists wish they could do, as it would help them to better understand how the brain works.
Scientists in Freiburg and Basel, Switzerland, have developed an implant that is able to genetically modify specific nerve cells, control them with light stimuli, and measure their electrical activity all at the same time. This novel 3-in-1 tool paves the way for completely new experiments in neurobiology, also at Freiburg's new Cluster of Excellence BrainLinks-BrainTools."
This is pretty awesome. Many of you may not know about research they are conducting in how to manually stimulate the brain to potentially cure psychological disorders(such as depression). Learning to manipulate individual cells with accuracy may allow us to potentially re-wire the brain to improve or even eliminate chemical imbalances.
It's been a long day, so I'll leave this one up to you to decide the implications. All I'll say is, yet more awesome science.
