Movie 1.

Wild-type DCV movement. A spinning disk confocal video of DCV movement in the ALA neuron in an ida-1::gfp worm. The nerve terminal (microtubule plus ends) is on the right. Kinesin-driven DCVs correspond to particles moving to the right, with dynein-driven DCVs moving to the left. The frame rate is 2 times real time. Scale bar = 5 μm.
