Controlling monkey’s brain by ‘light’!

Scientists have been able to affect the behavior of a primate using optogenetics—a technique by which genetically modified neurons are made to fire with light!To control the electrical firing of a neuron, scientists use a virus to deliver a gene into brain cells. The gene is designed to produce a light-responsive protein.Depending on the type of light-sensitive protein used, this genetic modification will either activate or silence a neuron in response to a specific color of light, delivered via optical fibers inserted into the brain.

The seven-year-old field of optogenetics has given neuroscientists a more precise tool to examine the connections between the groups of neurons that set up neuronal circuits. These brain circuits control behaviors such as movement and emotion and, when faulty, can lead to diseases ranging from depression to Parkinson’s.

The behavior studied in today’s published report is quite subtle: two monkeys were trained to purposefully move their eyes to a target on a screen when given a cue. But when the relevant optogenetically ready modified neurons were stimulated by light from optical fibers inserted into their brains, the neuronal circuit responsible was sped up, and the monkeys were able to complete this task faster.

Control stuff by brain waves..!

Firstly,I guess you need to know more about the brain waves.The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment (such as an EEG), measuring electricity levels over areas of the scalp. The combination of electrical activity of the brain is commonly called a Brainwave pattern.

Find the more info about this here… You may also google it… 😛

Coming to the main topic by using these brain waves we can control the objects….You can understand this more easily by checking this video out….

So,in other words we can say that we ourself are controlling the television set without remote.But,only with our thought..!!
