Hairless lab mice, 1975.

MIT is building mind-control helmets for mice, hoping to eventually have domain over brain functions in humans in order to control disease. An excerpt from a Discover article:

“Christian Wentz from MIT has designed a hat that wouldn’t look out of place at a horse race or a royal wedding. It consists of two circuit boards and an antenna, and it’s being modelled by a mouse. Wentz has wired the hat directly to the mouse’s brain and he can use it to control the animal’s behaviour with flashes of light. And most importantly, he can do it from afar.

The wireless helmet is the latest innovation in the exciting field of optogenetics, where scientists can use light to control the behaviour of both cells and entire animals. The typical set up involves loading cells – usually neurons – with a light-sensitive gatekeeper protein. When the protein sees the light, it opens up and allows ions to enter the neuron, making it fire.

By introducing the proteins into the right spot, scientists can switch on specific parts of the brain, or even individual neurons. They can turn on aggressive or sexual behaviour or make animals walk in circles. The technique promises to revolutionise our understanding of the way the brain works. It could even help to develop treatments for diseases.”
