We'll eventually get a hugely long tape, which is essentially the whole brain. "We essentially shave off a spiral cut as we rotate the brain on a lathe and put this ribbon of tissue onto a tape. "We do something akin to paring an apple," explains Lichtman. This machine reads the wiring diagram of a brain. As the animal grows and ages, they can also watch how the neurons change connections.Īnother technique uses the ATLUM, or automatic tape-collecting lathe ultramicrotome. By generating images of the animal's brain, scientists can see where and how neurons connect to each other. One such technique, known as Brainbow, labels every neuron in a live animal's brain a different color. Read on to learn how researchers map the brain. Researchers must collect images of the brain, turn those images into data, and then use that data to analyze what happens in the brain as it develops. Scientists are still developing the parts that might form this massive map.īrain mapping is a collection of many different tools. It could show us our whole brain all the regions, functional lobes, specialized centers, thick neuron "bundles" connecting brain parts, neuron circuits, single neurons, junctions between neurons and finally, neuron parts. A complete structural map of our brain might be similar. Google Earth shows us satellite images of our planet and zooms in to continents, countries, states, cities, highways, streets and buildings. Brain mapping also examines what goes wrong physically in the brain during mental illnesses and other brain diseases.įinally, brain mapping aims to give us a thorough picture of our brain's structure. It examines how our environment changes our brain's structure by studying, for instance, how the brain changes physically through the learning and aging processes. Now, can we look in the vision section and say, Is there a special part of the brain that detects red objects and another that detects green objects? Or does the same area detect objects of both colors?īrain mapping also looks from the outside in.
There's part of the brain that has to do primarily with vision and other parts that have to do primarily with sound.
