Largest brain map ever reveals fruit fly’s neurons in exquisite detail
Researchers now have a map of the brain of a single female fruit fly that includes nearly 140,000 neurons and captures more than 54.5 million synapses. The map was described in a package of nine papers by a consortium known as FlyWire, which is co-led by neuroscientists Mala Murthy and Sebastian Seung at Princeton University in New Jersey. It has been in development for more than four years. The map shows how neurons connect through chemical synapses but doesn't offer any information about electrical connectivity between neurons or how neurons chemically communicate outside synapses.
