Scientists believe that the Transcranial Direct Current Stimulation (TDCS) is a new process that sends electricity to the brain that boosts memory, focus, energy, and vigilance.

The jolt to the brain also may even allow for people to increase their learning capabilities and even learn new skills. These positive effects are only a few of the cognitive improvements that can happen for the human brain.

Apart from these benefits, researchers posit that implanting a chip that can deliver electrical stimulation can also possibly clear away depression and prevent cognitive decline.

Moreover, the TDCS implant can also transmit sound to the brain for deaf people, and allow for blind people to see with the use of a tiny video camera that captures motion.

Unlike the precise approach of a scalpel surgery, the TDCS jolts are more in-line with a shotgun to the different parts of the brain, says neuroscientist Michael Weisend.

A broad beam is sent along the brain to a specific region they are trying to target. While the approach is inaccurate, test results have shown that the techniques are safe, having been tested on more than 500 people.

The technique is capable of improving memory, pattern recognition, and a person's attention span. He adds that people learning new skills learn faster than people with no electrical stimulation.

While the future looks bright for the brain and its uses, the key will be in unlocking how the brain works.

Professor Gary Marcus says that the more they understand how the brain works, the better these devices can get.

He even talks about the possibility of placing a chip in one's head that will allow a person to directly download information into the brain, like the hit movie the Matrix.

"I don't think there's any doubt that we'll eventually understand the brain," says Marcus. "The question is how long it's going to take."
