Class I ddaE neurons can regenerate from the axon stump. a An axon of the Class I ddaE neuron (cell body marked with an arrowhead) was severed 24 h after laser-mediated ablation of the neighboring Class I ddaD neuron. The site of injury (orange arrow) is located near the dorsal bipolar md neuron (dbd). b The same neuron was imaged 96 h after injury. Growth from the remaining axon stump was observed. c Out of 10 axotomized neurons, 4 neurons showed stump growth and 6 neurons did not grow from the stump
