Controlling Brain Wiring With the Flick of a Chemical Switch

With the flick of a chemical switch, researchers can now
exert unprecedented control over the activity of molecules
that help wire the developing brains of mice.

The new technique permits researchers to use drugs to switch
the molecules on and off as precisely and reversibly as a
light switch controls a lamp.

Current genetic and chemical manipulation techniques are more akin to eliminating entire electrical circuits or breaking the light bulbs in the
lamps.
