Researchers use LCD projector for mind control

The Georgia Institute of Technology have managed to use inexpensive components from ordinary liquid crystal display (LCD) projectors to control both the brains and muscles of tiny organisms such as worms.Hang Lu and graduate students Jeffrey Stirman and Matthew Crane are the people who is using LCD projectors to control the brains and muscles of tiny organisms.Hang Lu is an associate professor in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology.To control brain circuitry they are using red, blue, and green light from the project. They use the light to move the organism.

Fibrosis, if it becomes severe, can lead to stiffening or thickening of portions of the heart, which can contribute to irregular heart function and, eventually, heart failure'.
