Representative images (top) and schematic (bottom) of intact and fragmented Hb9 motor neuron synaptic boutons in young (day 3) and old (day 40) flies. The synaptic bouton size is smaller (GFP, red, top), and the number of active zones per bouton is reduced (green, Brp, bottom) in old animals compared to young animals.
