 Scientists Use Drugs And Light To Control Mouse Behavior

Coming soon to a government near you.

No longer do test subjects have to be connected by wires to have direct brain stimulation applied. In a recent breakthrough, scientists from Washington University School of Medicine and the University of Illinois have developed a new method of delivering drugs or light stimulation to the brain of a mouse, using remote control.

Using a less than hair thin electrode implant is allowing the scientist a less invasive way of experimenting with direct neural stimulation, and remote behavior control.

So now, the mouse controls the mice

Scientists have successfully altered the neural networks of laboratory mice using a wireless controller; allowing them to study the effects of neural stimulation without invasive procedures and without test subjects tethered by wires.

The tiny implant, smaller than the width of a human hair, let the scientists determine the path a mouse walks using a remote control to inject drugs and shine lights on neurons inside the brain.

Neuroscientists have until now been limited to injecting drugs through larger tubes and delivering photostimulation through fibre-optic cables, both of which require surgery that can damage the brain and restrict an animal’s natural movements
