Map of adult insect’s brain offers clues on neurological diseases

International collaboration plotted 149 metres of biological wiring in fruit fly
The fruit fly ‘connectome’ contains a wide range of information, from cell types and synapses to neurotransmitters and network properties

An international scientific team has built the first map of an adult insect’s brain, offering a potential breakthrough for our understanding of how the organ works and why it is harmed by neurological diseases.

The project plotted the full 149 metres of biological wiring that make up a fruit fly’s poppy seed-sized brain and govern the organism’s life. It promises to boost knowledge of the human brain since the two species’ organs share many common features, including genes linked to neurological conditions that afflict billions of people worldwide.
