First wiring map of insect brain complete

This will help scientists to understand the basic principles by which signals travel through the brain at the neural level and lead to behaviour and learning. An organism's nervous system, including the brain, is made up of neurons that are connected to each other via synapses. Information in the form of chemicals passes from one neuron to another through these contact points. The map of the 3016 neurons that make up the larva of the fruit fly Drosophila melanogaster's brain, and the detailed circuitry of neural pathways within it, is known as a'connectome'. This is the largest complete brain connectome ever to have been mapped.
