The human brain is estimated to have over 100 billion neurons. Each neuron connects hundreds to thousands of times, creating a dense, complicated network of over 100 trillion connections. Scientists have the obvious challenge of mapping neuronal networks in a forest where all the trees and roots look identical. To differentiate between individual neurons in a network, researchers have developed the Brainbow technique. Brainbow labels each neuron with a specific color, allowing researchers to follow the pathways from one individual cell to the next. Seen here is the Brainbow technique used in a mouse brain.
