Neuroplasticity

In Old Brain, New Tricks I read about neurplasticity and rewiring the brain. In the article, a researcher developed a way to rewire a person's brain using only a camera and a postage stamp-sized plate that is placed on the tongue. He was able to give blind people vision again. For pulses were sent through the tongue into the brain depending on the colors that the camera picks up. These pulses would be known as the sensory imput and so would be sent to the parietal lobe of the brain, which is the sensory cortex. But since the person is see this, the impulse has to some how be sent to the occipital lobe that contains the visual cortex. So the sensory cortex would need to send this information to the visual cortex in order for this to work. The best part about this whole thing is that the parietal lobe and the occipital lobe are right next to each other so they would esaily be able to communicate with each other. All that would be needed are a few interneurons to transmit the pulse from the sensory cortex to the visual cortex. Over time, the sensory cortex would grow and become stronger, soon almost taking over the visual cortex.
