2018 July 19 – Scientists at HHMI’s Janelia Research Campus have taken detailed pictures of the entire brain of an adult female fruit fly using transmission electron microscopy. The fruit fly brain, roughly the size of a poppy seed, contains about 100,000 neurons (humans have 100 billion). Each neuron branches into a starburst of fine wires that touch the wires of other neurons. Neurons talk to one another through these touchpoints, or synapses, forming a dense mesh of communication circuits. – hhmi.org
